I have a Pioneer Avic 8000nex that I installed in 2014. No problems ever...until now.

Sound cuts out for radio, satellite, iPod, etc. BUT not when I receive a phone call. Sound works fine then.

Things I've done:

Pulled the deck, no wiring issues.

Checked the Alpine amps and no issues.

Checked each speaker in the 4 doors and no issues.

NO it isn't a loose wire and you hit a bump and it cuts out. Here is what it has done:

Drive the truck, no sound. Stop and park, turn truck off and come back 3-4 hours later for Lunch.

It works! No movement of truck or anything. Then it may work for 1 minute, day, or 3 weeks and then the sound will die.

I'm Losing my Mind on this! Any ideas?

 

LATEST Progress:

Updated Firmware from 1.14 to 1.21.  It Solves the Sound issue but then the GPS will not work.

Reinstall the GPS Maps, GPS works but then the sound won't work again....Whats going on I'm Losing my Mind on this! Any ideas?
