unlock 03' head in an 02'?


Recommended Posts

I currently own an 02' Olds Bravada. I want to add XM radio but dont want the look of an aftermarket head. I installed and 05' H2 head and it worked for a while then the unit LOCKED. I have talked to lots of people and get different answers as to whether or not this type of change can be done. The 02' does have the bus II controls but the problem lies in the VIN numbers not matching. Even my dealership couldn't unlock the H2 head with a Tech II. Any advice?

Take it back to the dealer, have them hook the Tech 2 scanner to your vehicle. When the Tech 2 first powers up, it asks you to "Build" the vehicle, in other words, what kind of vehicle are we working on?

 

The tech's mistake is that he is putting in "02 Olds Bravada" - have him build it as an 05 H2. Then go into the radio menu and choose the "Clear Theftlock data" function. Once this is complete, unhook Tech 2, key off, key back on and the radio will reset.
