[QUOTE="zane, post: 20503, member: 540617"] Ok, heres the deal....... GM's "Theftlock" Radio's are equiped with several electrical add on's that relate to the rest of the vehicle. The main concerns here would be with the SCV circuit that adjusts the volume to compensate for road noise. Also, removing the radio will cause it to be useless if ever installed again. There is a code that you can program into your radio that will allow you to disable the "Theftlock" feature however, so that should take care of that issue. Refer to your Owners Manual for the proper instructions on setting this code for your car. Basically, I "borrowed" my fathers 97 Chevy Silverado 2500; which has the premium "Theftlock" AM/FM/ Cassette/CD system. Did a little snooping under the dash- and there are quite a few more wires coming from the back of the radio than would appear on a typical- 4 speaker, standard power, Preout unit. None of the wires appeared to be interlinked with the Airbag system in any way durring a brief inspection of the main harness. Again, based on this- I think the SRS is not going to be an issue for you. However, GM specifically warns (in big bright red letters!) of adding aftermarket audio/visual equipment to the factory system due to its integration with the vehicle. While I believe that all you need to do is program your "Theftlock" code and disable the system to remove it; without knowing which specific radio and the layout of your cars main power wiring harness, I would still discuss this matter with a GM technician before attempting anything. take it easy, -zane [/QUOTE]
