Okay, I ordered the pdim installed it. Asked dealer to program for me. Said they did it. Plug in Android - nothing. Plug in iTouch - nothing. When they are plugged in, they can both charge.
Brought it in second time and they replaced the radio. They said this should fix it. Long story short they said it didn't work, iTouch disappeared (claimed honest mistake, told me to call back Monday), and the Android still can't be recognized.
Is this anything other than a failure to know how to program the computer properly? Any way to eliminate all other variables (bad PDIM module, bad wiring job)?
