I installed a cd player in my 2001 tahoe yesterday. It worked fine with the key in the accessory posistion but when I turned it to the on position it would shut the sound off but the cd player would still have power. I talked to a stereo shop and they told me that I have to get a relocation kit and an On Star interface. Apparently the stock cd player runs the air bags and the On Star. He said I have to get the relocation kit and install the stock cd player under the seat or in the console because it has to be powered and left in the tahoe. Is all of this true? Is there anyway around it. The On Star interface is $149 and the relocation kit is $70. Any help on this would be great.
