Black screen / stereo JBL stock unit

Hey guys. 2022 premium. I went through a river crossing last weekend and about a week later my head unit is just not working with no warning. I checked grounds and fuses and there all good. Anyone have this happen?

I did notice I’m missing a plug on my inner fender leading to firewall. I’m assuming water got in there and curious if there’s electrical connections in there I can feel a wire. Thanks.

 

Unrelated to your JBL HU but you need to check all your fluids for water intrusion in lieu of differentials etc.

 

With power to the truck on, have you tried holding the Volume button in for 15 seconds?

 

Not 15 seconds I can try when I’m off work. So far if been told to unplug it and replug it in. I’m just stressed there’s some type of electrical connection where the water gets in to the firewall and corroding a connection. I don’t even know if I can access inside that hole besides removing the cowle

 

Are you able to see the backup camera when the shifter is in Reverse?

 

yeah

 

Here are 2 things to try which is worth a shot.

Awesome thanks for the link

 

Please let us know if it fixes your issue or not.

 

None of the tests have fixed it. Looks like it’s going to warranty

 

Glad to hear you are still under warranty.

 

Did you end up getting a replacement under warranty? My JBL screen went black about a week ago, also 2022. Like yours, the backup cam still displays but nothing else. I’ve tried disconnecting the battery but will try the reverse thing shown in the linked video. Unfortunately I’m just past my warranty at this point.

 

No what I ended up doing was buying the Sony xav9000 from trail grid pro since it since it’s plug and play. I like it a lot better than the OEM. Of course it had some quirks but it has way more customizable options and wireless CarPlay. Plus the volume can be way louder now as well. That’s the route I would look up. I got the 9,000 and not the 9500 because I don’t need a huge ass screen in my truck lol

 

Good to know. I tried the stuff in that video above and neither fix worked. Sucks that such a major component as a head unit would fail after only 36K.

 

I know. Whole reason I bought a new truck was to not deal with constant issues and then boom radios gone after a few months. But like I said the Sony is a major upgrade so I’m not too upset anymore.
