Help Needed with Navigation Yukon XL 2003

Ok, my apologies for probably having this question asked before but I am in need of a direct answer before I invest some money and loose it. I have a 2003 Yukon XL that has the bose system with XM radio. I have verify that it is not a Y91 or Y92 but a UQ7 which my understanding is that is a NON LUX Amp.

From what I have read all indications point to me getting a replacement unit that is also a NON LUX Amp unit such as GM part # 15108421 (2004) which is the old knob style or # 15800000 (2006) which is the newest touch screen NON LUX amp.

I called a good friend of mine from back home who is the service manager at a local GMC center to asked him if it was possible to do a swap of units to have the navigation system. His answer kinda surprise me because he said that they tried one time to do this and they did everything possible and it would not work. He said it had to do with the software on the vehicle.

So now I find myself asking for your opinion on what is the real answer to the project that I want to accomplish. Can any of the two units listed above be use to upgrade/replace my current system to a navigation system. Is it pretty much a plug and play? Or does it involved major overhauling such as replacing harness and who knows what else. Your thoughts are greatly appreciated.

You might want to ask that question over at chevyavalanchefanclub.com; although I'm fairly sure that it should work on your '03 (you might need to connect the VSS wire to the nav unit); as long as the nav unit (either non-touch or touch) is programmed to work in a non-lux setup (it is possible to reprogram a lux nav unit to work in a non-lux setup but that would require a bit more work than just getting a non-lux nav unit to begin with), you should be able to install it in your ride...but again, you might want to ask at the website I just mentioned.

Well I have finally upgrade my system to a touchscreen unit gm#15800001. Yes you can have a LUX unit convert it to a Non Lux Unit. I am very happy with the result everything works great. Plus I got everything for under 500.00.:)
