does the clock on the cd player get reset too ? everytime u start the car ? i mean does it reset itself to 12 : 00 everytime ?
confirm this...if it does reset then i have the solution...and also if this does happen...ur installer was an idiot to begin with....
basically what he did wrong was connected both the "red" ignition and "yellow" power to the "Yellow" power wire from the harness.,... whereas the ignition wire should be connected to the proper ignition wire from the harness(grip) at the back... which means yellow to yellow and red to red... the harnesses(grips) in question are the factory harness and the pioneer pre harness...
