I have a 03 silverado that I hook up a ego talk bluetooth to the factory radio according to the directions. It seems to have a draw on the batterey when the truck is off, I'm pretty sure that it is wired correctly, but does anyone have a wire diagram for the 03 Silverado non Bose but w/ OnStar?
Thanks in advance
There is no switched 12 volt wire on that radio. I am not familiar with that bluetooth module, but if you got all of your connections at the back of the radio, your unit is probably staying on all the time. There is one fuse in the fuse box under the hood that is a switched 12 volt source. I have no idea what it is labeled but I know that there is one.
