  Alright truth is that the dealership you talked to is correct. There is an external antenna that needs to be installed as with any gps product. Also you do have to have the radio programmed in order to unlock it. The new radios built by denso have a data recognition of the VIN number stored in the radio and it will have to be programmed to work with the vehicle also ... Read More

  Sounds like you got an excellent deal. I've been on the hunt for a leftover 07 or 08 Silverado/Sierra, ext cab 4x4 with the 5.3 Flex fuel engine. Found a few leftover 07 recently and dealer quotes were $500-1000 above invoice. Haven't really followed up since the rebates are still $2000 for 08s and $3000 for 07s. GM card rebate is still $1500.

  Alright here's the scoop. All chevy's with factory nav have the Bose System from the factory and that is factory amplified sound system. The reason the sound is not very loud is you are missing the amplifier that is normally amping up the outputs from the nav unit. To fix this problem them there is one easy way and that is an aftermarket 4-channel amp. And the back up camera is ... Read More

  So what your dealership is saying is that you need to buy the nav from GMC directly or actually any GM dealership and they will do the install? There is a security system that is tied into the radio and I would believe that the ECU would probably have to be reprogrammed so that the truck knows the stock unit was replaced with the nav unit. Course depending on your relationship ... Read More
