Final verdict on NAV please!!!

[SUT_KID]

Thanks for the reply. I have sifted through the info on this topic but see 2 differnt answers. I have a 2005 HUMMER H2 SUT with "Y91" in the glove box. I have read through the strings here and have learned that this may not mean FOR SURE I have the LUX amp. WHat is the easiest way to know for absolutly sure? I have also heard 2 differnt part #'s stated as the "correct one". If I find out for sure I have the LUX amp (which I am 75% sure I do). Do I need part # 10377531 or part number 10377287 to simply plug in (in addtion to the GPS antena install) and retain the steering / onstar controls etc. without re wiring or cutting wires? Please clarify!!!!! Thanks!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

The way i determine is to took at the AMP. Physically they are different. This is a LUX amp, part numbers dont matter as much as physical appearance. An AMP that looks like this one, will never be a basic AMP, it will ALWAYS be a LUX.....

The non-lux amp is more of a boxy shape....i couldnt find a photo of it, but it is not as long as the lux version.

the 10377531 nav unit is for the lux setup. If you have a GM tech hook a Tech II programmer up to you H2 He can tell if you have the lux amp. The tech II can "see" the lux amp but it can't the see the non-lux amp. As linda said visual inspection is the surest way to check, but that may not be so easy to do on a H2.
