Default GM nav radio and onstar install questions

Whats up guys . just got my hands on a NAV unit from an 06 H2 . part #s GM 15800001 delphi # 28032960 . this is a TNR or touch screen unit . so today i went ahead and pulled the JVC radio that was on my truck and find out that who ever installed this JVC left the factory plugs so i was able to just plug in the unit and as expected i got the theftlock message so i need to have this thing reprogram ,the same guy who go tthis for me has a tech2 he mention that when ever i wanted he could do the programing for me ... .. I need to find out what the part number is for the antena for the nav and also the part number for the xm module that i need ????????? since the previews owner removed .

look at this pictures , this is what it looked like when i pulled the old radio out ..



i need to find a smaller antena conector they installed a bigger one that wont work on the GM unit


looks like who ever installed my DVD head rest ran this cables upfront in case somelse wanted a DVD headunit ..




Looks like the door speakers were rewire all 4 are aftermarket i also noticed that there are cables runing to where the factory amp is located .
I wonder if after the NAV unit is matched to my truck since it looks like they changed the wiring how would i be able to tell if the unit is working ,i mean how do i know that the factory harness is throwing any sound anywere ????
I any of you is a stereo guy please explain if i should rewire everything to mach the stock install again .....

finally got the nav unit unlock . because of what the last person to work on this truck stereo did i have no sound . i need to find the part number for the harness that hooks in to the back of the BOSE amp since there was cables cutoff ... basicaly the last stereo shop to touch this truck wired the aftermarket radio to the factory amp and they simply left lots of cables hanging around . i also need the xm wiring harness and the gps antenna ...

I know the thread is a bit old, but my suspicion is that you do not have sound because you bought a 15800001. This radio requires a digital LUX amplifier to work. Some 03 and 04 H2s came with a LUX amp. 05,06,and 07s did not.
You probably needed to buy a 15800000 which is radio compatible with the premium non LUX amp. That's what happened to me when I bought my radio and had to return it and buy the other model, and it worked then.
The Y91 LUX RPO is not indicative of a LUX amp as most Ebay sellers tend to imply.

what i ended up doing was buying a lux amp and rewiring the harness for a lux amp . now i just need to get the TECH2 and reprogram the amp for my truck since this one was on an escalade . when you swap amps sometimes you need to tell the amp its on a new vehicle . the way to tell if you need reprograming after the rewiring is done would be to turn on the radio and if you only get sound from the front passenger side door speaker thats the way the trucks tell you you need to program the amp .

Sounds like you are on the right track to putting her back right. That is the catch with these newer vehicles with factory amps and all and trying to go aftermarket. There is nothing wrong with adding an aftermarket head unit if you get the right electronics and harness adapter module. When done that way you retain the factory amp, all factor connectors, wiring, etc. Then if you ever want to put a stock head unit back in its just a matter of unplugging things and plugging the new one in. Most places also just use a short antenna adapter cable to adapt the stupid tiny GM antenna connector to the standard larger size one versus cutting the small GM plug off. Personally I think the Bose Lux setup sounds decent enough but I'm not fond of the stock head/nav unit. I used the proper adpaters to retain the stock wiring, connectors, Bose lux amp, etc. I did however delete the useless analog Onstar and repurposed its mic and GPS antenna for my Kenwood head unit though. For that I did cut the Onstar connector off and soldered a 1/8" mic connector to the wires so it would plug into my Kenwood and I bought an adapter to change the Onstar GPS antenna connector to one that plugs into my Kenwood.
