My boss gave me the RDS Radio out of his 2003 GMC Sierra Truck, I have a 2003 Chevy Trailblazer. The radio he gave me is a stock radio, but it is also the upgrade version of my stock radio. These 2 radios were only made 1 day apart from the same factory. I have inslalled this just fine, required same hook-up I have. My problem is that is is locked. Anyone have any idea what buttons to use to unlock this? My boss never put in a code. Took it to the dealer, they said leave it with them all day, will probably be very costly and take a while to do.
Any help would be appreciated!!!

"Starting in 2000 on the Venture, there is a data line between the radio and the car's computer. The VIN is assigned to the radio. If it doesn't match the VIN in the computer, the radio auctomatically locks. The dealership must re-assign the VIN using the Tech 2 device, as alluded to above. If the radio is an upgrade (CD when you only used to have cass, for instance) there is some additional programming required to make the computer see the new radio RPO code.

And yes, certain functions are lost if you remove the factory radio. It has more affect in some GM vehicles than others. GM has done an excellent job of making it difficult for people to go with aftermarket radios. Personally I think they look like crap in most vehicles anyway, so I won't shed a tear. Unfortunately, the process of swapping radios seems to be a mystery to some dealerships. Part of it is because there are compatibility issues between years and models but part of it is ignorance or lack of training on the part of the mechanics." (Written by someone on another forum).

I hope this helps. I have personally not dealt with this so I really can't provide you with many answers. A friend of mine is a service manager at a GMC dealership. I will ask him and see what he says.
