No power to radio and nav system after battery replacement

[jaydog82]

Hi all, after leaving my 2012 Alphard sat over the Xmas period I found that my battery had discharged. After a jump and a charge I have got it going again (battery is only a year old). I thought all was well but I have no power to the radio/nav system which means I also have no reversing camera.

 

I know there is a window reset trick after battery replacement (which wasn't needed) but I wonder if there is something similar with the radio and reversing cam????

 

I cant find any youtube vids or related topics on here  Please help

Hello jason maybe a daft question have you checked fuses as you might have blown one also if no luck try asking north star conversions

I would go along with the blow fuse check. Maybe the jump start blew it. I think its in the passenger bay fuse box. Depending on your head unit, the rear camera will be powered from that. If its an aftermarket head unit, then they probably took the power from the same cable as the head unit
