Gfirkser Posted April 13, 2020 Report Share Posted April 13, 2020 Pioneer Navi X930bt Hey, I recently had a battery replacement and the main fuse had blown in the process. Navi unit is showing no signs of power and I've checked the car electrical fuse box for any broken fuses. None found. Any troubleshooting I'm completely overlooking here? Does the pioneer Navi have its own internal fuse? Quote Link to post Share on other sites

AVIC-X930BT_InstallationManual040511.pdf What is a "main fuse"? You need to check check that both power wires have 12VDC (red=switched, yellow=constant). They would be on two separate circuits - so two fuses. A voltage/multi meter would be useful. However, I suspect someone screwed-up when replacing the car battery. Maybe + and - wires got switch or shorted. You don't normally blow a fuse when properly replacing a battery. If something did that, it could easily of fried sensitive electronics.

Ya o have to check if power is making it go the unit and then if the unit is toast. I just want to access the fuse first. Quote Link to post Share on other sites

All double-din units mount the same, but the trim removal for each model vehicle will be different. If it isn't obvious how yours is removed you'll probably need to post question on some forum for your specific make. Quote Link to post Share on other sites
