Jeff and the crew at KarTunes installed a Kenwood car play deck in my 2011 Yukon. I asked that they use an existing USB connector in the cigarette lighter socket, but when it turned out to work inconsistently, they diagnosed the problem, and spent over an hour routing a new line to my iPhone and correcting the issue...at no charge to me. I'm a big fan and a very satisfied customer. These guys know their business. I highly recommend them.
