Had battery charger on, gps on , and started engine must of shorted gps out. When battery switch goes on ,gps turns on to a blank lit screen.On and off switch doesnt work. Any idears on inline fuses on wire or inside unit itself before sending out?
No sorry. I bet that baby took a voltage spike. One should always turn off all accessories prior to starting the engine. Once the engine is started then turn on the needed accessories. I think you need the help of SH professional repair.
