Pioneer AVH 3700DAB Radio Power issues

[mavisnderek]

Just recently, my Pioneer radio (with SatNav addon) has stopped turning on with the ignition. To get it to work I have to switch on the Motorhome's Auxiliary power. It used to be fine, even after I had a new head unit fitted last year. Any thoughts out there?

Try the fuse in the ignition live feed.

Thanks for the reply,but would that be the one in the engine compartment (F03) or under the dashboard (F36) see attached, Cheers.

Check for an in-line fuse around the radio iso connector and check for voltage there when you turn the ignition on.

it will either be a red or yellow cable. One is permanent live (usually yellow) and one will be the ignition live (usually red).....

Different manufacturers cause confusion using by switching the red and yellow.

What year is the van?

Do you have any issues with anything else that F36 supplies? Although it says it’s Bat+

Are there any more Key+ fuses in the dashboard fuse box that you’ve takes the screenshot of?

The 2006-2014 fuses would be as below

Pulled out the radio and noticed the yellow cable from the ISO connector wasn't attached to anything. Dug around in the wiring and found the female connection it had detached from. All working fine now thanks for pointing me in the right direction
