I did the same thing as Shiftz33, except that I hard wired the power to the cigarette lighter so that it could still be used as a power source. Also, I wrapped the AUXV2 in bubble wrap to insulate it. The dash top gets pretty hot in the sun, and I didn't want to have to do the job again in case something overheated. Micro circuitry can't take extreme heat well, I believe.
