I keep losing the channel presets on my AVIC Z2/3, not anything else. I program them in and after shuting off the truck I lose them, not all the time just sometimes. I've checked the connections and all seams good. I tried to duplicate it by disconnecting the 12V constant power but that turns off more that just the stations camera, eq, sub and more. All I lose when this is happening is the channel settings they revert back to channel 1. I've reset it a few times with no help..

Anyone ever have this or any ideas..

Any help is appreciated.. Thanks

I believe there's an inline fuse on that wire. I think its a 15amp. Or has this always been the case because that means you wired it wrong.

It's wired correctly, it's been in my truck for 5 plus years with no issues. All of a sudden the stations will not stay programmed, if I disconecet the constant 12V wire not the ignition you lose more than the stations, the eq settings, camera and sub imput turn off. That's why I can't seem to figure out why just the stations go away and it doen't happen every time I shut it off, just sometimes..

Sounds like an internal hardware problem with a memory IC
