I HAVE A PROBLEM WITH MY AVIC-D1 UNIT, DURING NAVIGATION THE UNIT WILL BLANK THE SCREEN AND THEN REBOOT LIKE WHEN YOU FIRST START THE CAR, ANY ONE HEARD OF A PROBLEM LIKE THIS? I CONTACTED PIONEER AND THE CUSTOMER SERVICE REP THAT E MAILED ME SAID TO CALL SO THAT I CAN SEND IT IN, I CALLED AND A WOMAN TOLD ME THAT THESE UNITS THEY DO NOT REPAIR, AND THAT I NEED TO BRING IT BACK TO WHERE I BOUGHT IT FROM FOR AN EXCHANGE. HAS ANY ONE EVER SENT THEIR UNIT IN FOR REPAIR? PLEASE SHARE ANY INFO YOU MAY HAVE ON EITHER SITUATION, THANKS

I would check the power and ground wires first, does it do it when you are parked or when you hit a bump? Try running a temp 12v wire to see if this solves your problem.

i dont believe it is a power problem, because while the unit cuts out and reboots, i am listening to xm and the xm radio never cuts out even for a second, while everything else is going on, thanks
