JBL No Audio (Volume non adjustable)

So today i was unfortunate to have my 4runner stop giving any audio. I was pulling into get gas and the audio dimmed as if i was getting a call (i was using the aux). Didn't look at my phone until i finished getting gas. When I was done I realized it wasn't a call and that my head unit volume control and steering wheel control stopped working.

- I've never messed with wiring since I am not confident in doing so. No new electronics have ever been installed to give someone a reason to touch my wiring either.
- I tried what other have done. Restart the vehicle multiple times, changed the radio fuse, and flicked the key to start when running to reset the head unit and still nothing.
- Took it to a dealer I have decent confidence in and they were unable to determine the problem. They requested I drop off the 4runner next week and take a loaner car giving their audio specialists a chance to do a thorough investigation.

I've searched online and the forums to see if anybody had this issue resolved since it seems common, but usually people are lucky enough to get it working after a restart.

Does anyone have any other suggestions? I know one guy hear had a blown amp and i think that fixed it but he never posted if that fixed his issue. I'm upset I'll be without audio for a week or longer depending on the issue :crybaby::crybaby:

Before I have someone say I might have been bumping it too loud to blow something, i always have the volume at 25-35 out of the full 60+ volume.

It's a defect with the JBL head units, I've heard of people swapping the HU out to fix the issue. Mine always worked by flicking the key to the start position and restarting the head unit
 
So the cheapest option would be to just replace the head unit?

I really wanted to upgrade the entire sound system add nav & bluetooth, but not something I want to do now.
 
This happened to me a couple of days ago and I just turned the vehicle off at the next stop sign and restarted it. It worked fine after that and has not messed up since, hope that helps.
 
Thanks man. Hopefully the dealer can offer a replacement unit for cheap. If not I will have to look into a kenwood or pioneer with nav. I know a lot of members feel like the jbl sucks, but I was pretty content with it

Yes, cheapest option is to replace the hu, however, you can add an aftermarket hu and keep your stock amp, you just need a PAC Tato converter
