2003 Yukon XL Navigation

[plaparoo]

I have a 2003 Yukon XL with a OEM 6 cd changer/radio/xm unit. I do not have the Y91 option. Can I install a newer OEM Navigation unit to replace the current unit? If so, does anyone know which models are compatible? Will I also need to install a seperate CD player?

You might need to make a minor wiring addition or two to the connector (I think this is necessary only if you wish to add the Y91 amp to your truck but I could be wrong--which of course would mean you would need to get the Y91-capable nav unit), but yes, it is possible to install the OEM nav unit; just make sure that you get the one that's for the non-Y91 vehicles (I forget which model number it is, but a search should get you the right number). You'll need to install a separate (slave) CD player/changer if you wish to listen to CDs while operating the nav, since the nav requires the map DVD which loads in the same slot used for loading music CDs...

There is a GM Delphi radio that is compatible with the NonLux amp trucks such as the Suburban and Yukon with the Bose NonLux amp. There are a few reputable folks selling NonLux and Lux radios and complete packages with the separate CD changer ala the Denali on ebay.
I bought mine from RadioBoy
Here are the radio part numbers you need, or you can go the Lux model route with the amps and CD changer for a complete system.

Non-LUX touchscreen # 10397545, 15120706
TNR Non-LUX Amp 5600 series BOSE amp

LUX-Y91 touchscreen # 15230099, 10377531, and maybe 15118439

Fortunately I just had to swap out a touchscreen Nav radio for the stock unit in my YXL Denali and it was pure and simple a plug and play affair.

Here is the place to go to get the info, you will see a couple of threads about Nav radios and the 6disc changer install
