2003 Yukon Denali Navigation Radio

but you cant get anyone to sell one new....i looked. The dealers tell you there are none to sell, and look at you like you have 3 heads. They tell you even if they had one, it wouldnt work in your vehicle....such lazy liars they can be.


Can you give me the part numbers for everything you got ??? Please

Um8 NAV Head Unit----- #15204335,15204334--------------$1500
Nav Disk--------------- #15105609------------------------$200
GPS ant--------------- #15207447,15135178---------------$75
Mic--------------------#25705367------------------------$45

AUX harness---------- #15312903-------------------------$25
AUX CD changer-------#15055250-------------------------$180

thanks!!!!!!!

I have a 2003 Yukon XL Denali and want to upgrade to the navigation radio but have access to both part# 15204334 and 15204335. Anybody know what the differences are? Thanks.

If you have an '03 Yukon Denali, you dont neet all the parts listed above from gable74. I dont know what the difference is between the two part numbers you listed, but I replaced my '03 Denali with 15204334 (Radio); 15105609 (disc); and 15207447 (GPS antenna). It took less than 20 Min. to replace, and it works great.

thanks sprague.

what did you need the mic and amp for??? My truck has the 6cd bose in ti. I was hoping this could be plug and play. also, when you installed the in dash cd played in the lower dash, did you use the dash peice from a factory truck. you mentioned in another post you did some plastic work

The AMP was needed for my silverado because it doesnt have the "LUXURY" AMP thats needed for the Navigation radio to perform correctly. This AMP is found in the Denali's, Escalades, and Hummers. The MIC is not really needed, but to gain ALL the abilities that the new AMP will be able to provide, you can install it. To understand the MIC's function.....read the NAV operation manual.

I just put a Nav Unit from an H2 in my 2003 Tahoe. The whole install was very easy. It works fine, but I want to add a GMC cd changer so that I dont have to remove the nav disc. One question:


Where does the GMC cd changer plug into? The back of my nav radio does not have anymore plugs.

Thanks,


Chris

Anybody have a #15207447 GPS module for sale or know who has one in stock? GM has a 2 month backorder.

It plugs into the the [_] connector that's next to the main plug connector. There is an AUX connector next to the main plug, that is where you plug the cd changer into.

The easiest way to get the antenna is to get a VIN # from a vhicle that has the NAV as OEM equipment on it (new or used car). Then take that VIN into the parts dealer and tell him you need it quick. This will put a special case order on the part and you will receive it in less than 5 working days. Thats how i got mine, and it worked perfectly.

Also, on the CD changer question....you will need to pick up a wire harness (i posted the model # a few posts back), and make a few changes to it. When and if you get that far, let me know and i will walk you through it. Here is a pic of my set up in my 2003 2500HD silverado LT.

Ok, I had the dealer unlock the theft lock and the GPS works and I can hear the woman's voice that navigates. Their is no sound from the radio or cd player. My Tahoe has Bose and Onstar and the plugs were easy. The guy at the dealership said something about the unit being for a truck with XM radio and since I dont have XM, it wont work. ???

http://files.automotiveforums.com/gallery/watermark.php?file=/500/164003PICT0018.JPG

That is false but i'm not surprised given that it's a guy from a dealer. I don't have XM and the unit works fine. I get perfect sound and I have the monsoon amp in my car. Not bose.

Send me your E-mail, and i will send you the manual in .PDF form. By the way, i got mine up and running as well. It was a little trickier to do it in the Silverado, but i got it!

Can you email me that manual too?

ChristopherGDempsey@hotmail.com

JeepGuy...you need to upgrade your AMP and make a few wiring changes at the AMP harness. You need a bose "LUXURY" AMP like the ones found in Denali's, Escalades, and Hummers. I have some part numbers posted above. I had the same problem as you, then i got the right AMP and fixed the wires at the harness, and BINGO!

Here is the manual.........
https://www.mygmlink.com/pdf/go2content/manual/US/en/cadillac/2k04escalade_nav.pdf

Anyone have the wiring schematics for the Nav unit?

for which harness? there are 2 on the NAV and one at the AMP.

The main harness that provides power to the nav unit.

Hi all,

Took a lot longer to replace my console than I had planned. The first one I ordered never had the front part shipped, which left me mid project in serious dis-array...

Anyway, I ended up getting a new 04 Escalade console, complete. I've already sold my nav setup in favor of an alpine setup, but have some parts someone here may be interested in. I bought a new console, complete with wiring, amp, mic, 6disc changer, etc. It's never been in a vehicle.

The amp is 15054675. The changer is 15055250. Rear audio controls 15767145. Mic 25705367, and auxillary wiring harness (can't find a part number), but it connects everything in the console (amp, changer, lighter plugs, etc).

I don't check this forum every day, so if you're interested, email me at meeksebay@yahoo.com. If I don't get any takers in a few days, I'll probably put it all on eBay. If someone here wants the stuff, I'll sale it all for $600 shipped. Price a few of those parts, and you'll see it's a pretty good deal, especially all in new condition.

Thanks,
Josh

pacethis - How does your door chime and things like that work with your new Alpine setup? Does everything work as if the stock unit is in it? I have a Colorado with the new data bus setup and would like to install some sort of nav unit. I don't have the Bose sound system.

You'll need the right adapter. Mine was from Circuit City and like $70 or $80. It does an okay job with door chimes, power retention, etc...but not perfect. Occasionally, the doors don't chime, or chime for several seconds after doors are closed. Power retention sometimes stays, sometimes doesn't, occasionally stays even after truck has been locked. It does work fine 99% of the time though...

By the way, if you're going to install a nav unit anyway, I'd highly suggest going the factory route. It's going to be a better product for the money. Since you don't have the bose setup, you'd need the new amp, and maybe the speakers (I sold all the speakers from mine, including sub, for around $100). The right amp will cost you $300-400 (I have one available as of now) and you can get the nav hu on eBay for ~1500. Maps, etc will cost you another $200. All in all, it's not a cheap venture, but it is a nice setup.

I just decided I didn't really need nav, so I went with an alpine mp3 deck. Put the money towards a new console and some other things...

[QUOTE=jeepguy44]I just put a Nav Unit from an H2 in my 2003 Tahoe. The whole install was very easy. It works fine, but I want to add a GMC cd changer so that I dont have to remove the nav disc. One question:


So you didn't have any problems installing tha nav radio from the factory 6-disc in dash rds radio?

I could be wrong, but doesn't a GM vehicle with the factory-installed OEM nav unit also have wheel sensors (or similar) which help aid vehicle navigation tracking when the nav unit isn't able to pick up a GPS signal while the vehicle is in motion? I mean, the nav won't be able to accurately display your vehicle location onscreen if your vehicle is inside say, a tunnel...not unless it's psychic.

the vehicle (all gm 2003 and up) have a VSS wire (vehicle speed sensor). This wire is connected to the HU harness when the NAV unit is installed. This is what tracks your position when the GPS signal is weak or unavailable (which is almost never). A version of this signal is also what controls your AVC (auto volume control). So when you go faster, your radio gets louder and when you slow down, it turns the volume back down.

Almost never? Ever driven through a dense forest of redwoods? Or in a long tunnel? Not trying to be argumentative, but there are places where the GPS antenna may not be able to pick up a strong enough signal...or any signal at all. Yeah, I know you said "almost"...;)

Gable-

I've got the appropriate Bose amp now and my console is pulled apart. What are the changes you made to the harness so that it would work? I'll be trying a few things but any help would be appreciated.

I have the factory nav factory installed in my denali. there are plenty of times the nav systems gets lost.... or doesn't know where I am.

well, when i installed my GPS antenna i did not put it in a stock location. Maybe thats why i get better reception, i dont know. Sure, i mean for Gods sake if your in a concrete tunnel, your NOT going to get a signal, but in dense forest, fog, even inside my garage sometimes i get a signal. Maybe im just an anomoly. Jeepguy, send me an E-mail to "gable74@hotmail.com" and i will get you the literature you need to finalize your hookup. I was having some E-mail issues last week, but it seems to be fine now....so shoot me an e-mail and we will get you str8.

I'm been looking into getting a NAV system for my 2002 XL Denali...Here's the question, Can I upgrade my radio system to the GMC Integrated Nav Radio?

Thanks,

Hi all,

I've decided to put out the parts on eBay. If you want any of them, just bid. I'll give free shipping if a forum members wins any of them.

These parts might come in handy if you're planning on doing the nav install...many people run into problems with the stock amp and need to change to the new style. Get it here much cheaper!

I just wanted to say thanks for all the accurate information that I've found reading these posts. I have a '03 Sierra Denali with the factory Bose, steering wheel controls, rds, remote cd, onstar, and xm radio. I bought everything on Ebay except the antenna which I had to order from the dealer. I took the head unit to the dealer that I installed in my vehicle and they could not unlock it the first time. Then after providing a vin from a 04 Escalade which was equiped with the navigation, they quickey unlocked the head unit and everything works perfectly. I only have one question. Where do I mount the gps antenna? Now I know that the '03 Sierra Denali truck never had the option for this navigation sysytem, but the Denali Suv had that option in '04 which uses the exact same dash. I can't find anyone at the dealer that knows where to mount it and they will not let me take one of their new Suv's apart to see how it is mounted, at least I asked and they laughed? The antenna bracket looks like it will rest on something but I can't see anywhere to mount it. For now it's just sitting on the top of my dash to get a location. Does anyone have a picture of the mounted antenna? Just to let everyone know, I tried to order the antenna from Gmparts online and a few days later they rejected my order. I did what I read in one of the posts by providing a vin from a vehicle know to have the navigation system in it. Gm now has a new part # for this GPS antenna module is 15135178. It took only five days to get a new one, but I had to pay full retail of $90.50

I am selling my factory Delphi radio (15184933) that I replaced with a navigation radio if anyone is interested:

well, i changed to a nav head and changed the amp, and still no sound, apparently harness changes are needed, if anyone can help, i would appreciate it!!

just a note to anyone reading this,, if your going to try to do this in a silverado,, dont buy a brand new amp! you need one that is programmed, just in case this is not ridiculous enough already!

Do you mean that an existing amp that doesn't seem to work, can be re-programmed to work? I'm at the point where I have the navigation unit installed, and am having the typical audio issues that several here have written about.

Well, my latest understanding is that it not only has to be the upgrade amp, but has to have been used with a radio or nav unit that would be used with that amp, i guess if you are putting it in the type of vehicle that would use it you wont have the problem. if you are doing the rewire job for a vehicle that wouldnt, you have to have a lux amp that had already been in a vehicle,, i can tell you i wish at this point i did not even start this project, for the money i tossed so far, i could have put in the top of the line alpine, and not had any of these problems,, cest la vie.

In other words, if that was not clear, if you have the wrong amp, it wont work at all, and if you buy the lux amp, brand new,, guess what? it might still not work! but supposedly and its a big if,, if you buy the lux amp and it has been ina vehicle,, then it will work, oy vey.

Hi,

Can you post all the wiring harness schemes please? That would be really helpful.

Thanks,
GC

I have an 04 suburban with the bose system, onstar, xm, dvd, the works. As was true for everybody else, the dealership does not provide any helpful information. I spoke with a guy at a dealership, finally, that was actually helpful. He told me of a website www.jpcustoms.com that packages a factory nav upgrade kit for about $2200. It is expensive and I think I could do it for less. If I go out and purchase an integrated navigation radio from ebay, will all the functions on the steering wheel, rear controls, onstar continue to work properly? It sounds as though the only thing that will not work as great as a factory install is having the wheel sensors. I am all for having factory equipment as well. In addition to getting the head unit only, I believe I will need the wiring harness to add the 6-disc changer down below.

This thread has been extremely helpful. The only thing unanswered for me, will my bose amp work?

I dont frequent this forum much anymore so sorry for the delayed responses. I have 10 Luxury AMPs that i have personally tested that i know for a fact work with the NAV radio. I will sell them to anyone who E-mails me for less than $200 each. I also have one listed on E-Bay right now. On another note, this install is not nearly as difficult as some would make it seem. It is a bit confusing sometimes, but well worth it in the end. I have had mine running for about 6 months with no problems. I have full pictures, Documents, schematics and details on everything dealing with this install from the Head unit, AMP, to the 6 CD changer. Send me an e-mail if you need help (Gable74@hotmail.com) and i will do the best i can for you. Just be a little patient with me as i am helping quite a few people do the same MOD to thier vehicles. Here is a good post to read with pictures and some details.

I have to agree with gable, who has helped me immensely with this, it is not at all difficult if you have all the info going in. Mine has been working fine and I am quite happy with it. It was difficult and frustrating for me because I did not have all this info up front, thankfully gable saved my butt, and the nav system works great! thanks again!

That's like what I did. Except I have a 2002 Pontiac Grand am GT1. The unit works, but for some odd reason, it stays in night mode all the time when the car is on. I got mine from a guy who visits the another forum I frequent. He got it from a wrecked '04 Buick Rendezvous. I paid $500 for it. I couldn't pass this great deal up. :)

Anyway, what it doesn't have is the right gps antenna. I am trying to find out what the part # is for the correct gps antenna that hooks into this unit. I saw your unit on ebay and sent the seller an email asking what the part # was and he did not respond. So if you help me out here, do you know what the part # is? I am having a difficult time finding it. It's very frustrating. :(

Here are pics of the unit:

Hey your 02 gran am gt1 is plug and play for de nav unit. please let me khow

Need a recap please. I have 04 denali, xm, onstar, bose system etc. I opted not to get the nav system at the time of purchase. I have just purchased a nav system off ebay that came out of an 04 denali. Simply plug and play and should be good right? It should be linked thru my Onstar yeah? You mentioned a gps antenna, I thought this was the same as the Onstar one? Anything else I need to know before I install? I have the manual and the dvd coming with the head unit. Any help would be great. Thanks !

You WILL need a separate antenna that mounts under the dash. It does not integrate with the Onstar system. With the Denali, you most likely already have the Y91 audio package necessary to do this. You can check the list of codes in the glove box to check that out. And then, you will need to bring it to a dealer to get the theft lock removed. Hopefully you can convince them it is not a stolen radio, as some dealers are pretty strict about how and when they do this.

Cool, Thanks. Does the dealer have to unlock or can any car audio place unlock it? I know I need the dealer to plug it into the TECH 2 scanner..

Any place that has a Tech 2 and the instructions for removing the theftlock can do it. I'd be surprised if your neighborhood car audio place had a Tech 2, as it would be of very little use when it comes to installing aftermarket car audio equipment.

Can anyone post some links on what is needed like someone did previously? The links are no longer active on ebay and I was curious on what I would need to do this. I read about a microphone and I have one on the overhead console I think for onstar and another one that is above the driver seat roof. I have a 2003 Chevy tahoe with the bose setup except I dont have the xm radio built in. Will the amp work from this and does anyone know where the amp and the sub is located?

thanks for any input.

Ok after I was looking on ebay I think my radio might be XM also is there anyway to find out if it is?

I hate dragging up an old topic, but I just purchased a 2005 Sub with the NAV system. My wife and I drove several Sub's and Yukon Denali. We liked the Denali system set up with the six disk below the nav/radio and above the drink console. I am trying to get the dealership I bought the truck from to install the six disk as if it were in a Denali, they say it can't be done. My wife is nuts about having a unit look like it was factory. The dealer says it was not an option on Chevrolet. My thought is that they are the same unit, someone should be able to get the disk head unit and slip it in the "hole" above my console and then cable it to the nav/radio unit and it should work, RIGHT??? If that is correct, anyone got a part number for that 6 disk unit and maybe the PN for the cable harness if needed? Thank you so much in advance for any and all help.

Yes, the factory six disc changer CAN be installed in the lower pocket on the Tahoe / Suburban. Here is a link to where the changer, wiring harness, and installation instructions are sold brand new with a warranty. http://www.jpcustoms.com/store/customer/product.php?productid=16701&cat=354&page=1

I did this install in my Tahoe even though I use my IPod 95% of the time plugged in through the aux DVD input. The install is fairly easy except for a little cutting you have to do to the pocket and behind it. I used a die grinder and it cut the plastic like butter. If you screw up the bezel can easily be replaced. You can also find the changers on E-Bay but you will still need the wiring harness and instructions for the connections. All the changer controls show right on the Nav screen and it sounds great.

Thank you for the information. I was scrolling back through some of the other info and I may have gotten this from another link, but is there a way to tell which nav/radio head unit I have without tearing into the console mounting area. I saw there were two or three version out there, one with touch screen, one without, and maybe one that doesn't have a connection for the changer. I have the nav unit that is touch screen and when I click the disk button on the face, right now it says no disk because I have the Nav disk in the single cd slot. Is there a part number in any packets that I can look up or look my unit up by VIN to see which head unit I have so I can "blast" the guys that were telling me it can't be done?

Thanks again
Marc

There are touch screen and non touch screen units. Each version is either a standard bose unit or a bose luxury unit that uses a different amplifier. The lux bose unit is only found in the Hummer, Escalade, Denali, Etc while the standard bose radio's are in the Tahoes, Trailblazers, Yukons, Etc. The changer DOES NOT connect to a plug on the back of the radio. It has about eight different wires that must be spliced into the existing radio harness. The changer can be installed on any Nav radio regardless if it is Lux or non-lux, touch screen or non-touch screen. Hope this helps.

I'm not sure if this has been covered already, but you need to be very careful when buying a nav off of e-bay. When buying the nav unit, you need to be sure you buy one that is made for your type of vehicle. Navs for Tahoes, Yukon's and Suburbans require the nav for a premium amp. Navs for Denali's, Escalades, and Hummers require the luxury amp model. They are not interchangeable. Also when buying a used nav you need to have it reprogrammed at the dealer to match your vin #. Factory new navs do not require the tech 2 reprogramming from the dealer. The new navs should be plug and play.

I'm in the process of changing the nav in my 04 YD from the INR nav to a TNR (touch screen). The other day the dealer even made a mistake and ordered the wrong nav for my truck. They ordered the TNR for the Yukon when I needed the TNR for the Denali. They look exactly the same but they can't be interchanged.
