Nav Help!

[09gmc5.3]

Hello i recently bought a 09 gmc slt . And had 08 gmc slt with nav but the sytem i bought it of a guy from ebay and worked perfectly fine. And took it out and put it on the 09 the sound controls could not control it was just loud . So my question is do i need to buy one that really fit on the 09s because its has the bluetooth option or not?

My guess is the lack of volume control would be a programming thing that a dealer should be able to sort out for you. As for the bluetooth, my '09 Silverado has it and still has it with a aftermarket NAV radio, so it must be linked more to the onstar system.

 

(still have yet to understand why "the old" GM choses to make headunits so reliant on programming, and lets face it, theft-lock is a JOKE, I've had the GM factory NAV, I don't like them and have found some aftermarket headunits do much better)

But when i took it to go get it unlocked the guy said about some rpo's but i dont have the vin number that this sytem came off

I don't know anything about the Bluetooth system

 

I have read that there are "TWO" different AMPS for the trucks.

There is a "LUX" amp and a "NON LUX" amp.

The NAV unit has to match the type of amp or you get the problem of being unable to control the volume. (like you are having)

it has nothing to do with the bluetooth, you cannot use the 07 and 08 nav radios in the 09 and newer but you can use the newer one in the older ones, we have tried different programming at our dealer but can not get it to work just end up getting the 09 nav
