2014 Head Unit will reset itself randomly - Fuse issue?

I have a 2014 Limited with JBL sound system/head unit. It will randomly reset itself when I am driving. Wondering if this is a simple fuse replacement or if there may be a bigger underlying issue going on? I have had it since last July and LOVE it, but I find the resetting of the system an annoyance. I will replace it with a newer one if needed and it is possible, but figured I would start by seeing if anyone else has had this issue and or resolution. Thanks in advance!

 

Just went thru the same thing with my 2016 non-JBL unit. Didn't want the hassle of taking it somewhere and paying somebody to tell me they can't figure out what's wrong with it. So, I just replaced it. Wanted something with CarPlay anyway. Couldn't have been a fuse though because the replacement works flawlessly. Went with a Pioneer 4600NEX:

Did you have to make any mods for it to fit?

 

You need to replace the faceplate:

If you go through Crutchfield, you can get everything you need for a fairly painless install. There's no reason to have to modify anything or cut any wires.

 

Yeah here's the link same product just add all the extra wiring and it's a breeze. Plug and play

Just be wary that the unit you may be purchasing does not have stand alone navi.

Before replacing it, try reseating (and maybe cleaning) all of the connectors on the head unit. Could be some oxidation / corrosion on the pins causing intermittent connectivity issues.

 

Sounds like it is a known issue with Bluetooth (in doing more research) and that a software update would resolve - now down the rabbit hole to find the software.

You freaking ROCK! I found an older site (wayback machine) but it was a deadend! Thank you for this! @hvac guy

 

I had the same issue with my 2016 trail premium. I switched back to the original SD card for the map and no longer had any issues. I suspect my updated SD card map failed.

 

I did see the SD card could be a culprit but I am going to try the updated software first and see what happens! Will do SD card if it doesn't resolve. Did you get the SD card from a dealer or able to get it online? @KCSilverTEP
