Nav reboots while driving and electrics semi shut down.

jsoltan · 12-17-2013, 05:45 PM

While driving in any gear and at any speed the nav screen shuts down and reboots and the car cuts out momentarily. At the same time key fob doesn't open door locks. Battery changed out to OEM in last 12
months. What could this be?

Sounds like a loose connection from the battery to the fuse block.
Schematic attached, with the suspect connection noted.
