Navigation upgrade?
I just got through doing a GPS upgrade for our '04 Tahoe; simple plug and play and I've got navigation.
Can I do the same with upgrading from a stock AM/FM radio to COMAND in the C32? Is it plug and play? I see a ton of COMAND's on ebay but I can't really find info on what is involved in doing a total retrofit.
Can anybody post some details, or point me to a good source?
Thanks!
