Has anyone heard if GMC is working on a fix for the I phone volume problem? Every time I get into the truck the volume gets turned way down but doesn't go back up after you leave the truck. So the volume is so low you miss your phone calls and text's.
Bought some 3 light led strips and wired them into the 3rd wire (gray) of the white colored plug under the dash closest to the driver’s seat. Works great.
