would some one be nice enough to give me a shopping list of what i will need to install a avic d2 in my o6 hummer? i have ordered the metra kit. i would like to leave the factory wiring intact. thanks roadkingdoc!

if you use the metra kit, you wont have to messup the factory connections. For grounding, look for a grounding spot behind the kick panels. You would still have to run the reverse signal wire all the way to the back but you can search to see if that is nessesary. I use the reverse signal to activate my backup camera. Hope this helps.

H1 H2 or H3. Bose system, Monsoon, or neither?
