    Has anyone heard of any of these factory 7inch HU’s going bad?



    I had a JL amp installed and have had nothing but problems (over a multi-month time frame). At first the passenger side would cut out. Took it back to the place a couple times and they couldn’t duplicate the problem. Then yesterday the driver side started cutting out. I took it over there while it was doing it. The guy said they are going to try replacing the line converters, but also could smack the dash above the HU and the speakers would come back on. He mentioned that it could be the HU going out as well.



    Any thoughts?

    Loose wiring by that shop, or connector not fully pushed in.

    Sounds like he's trying to make it not his/their problem. Bad install, on their end.

    That's what i thought too, but couldn't really call BS without knowing about failure rates of the OEM

    I've never heard of one of our Entune units actually failing. There were some minor software issues that were fixed with updates.

    On the other hand I have seen MANY terrible stereo installations at "professional" shops. The radio is easy enough to pull out yourself. Pop the trim off and take a look for yourself and post some pictures. I would advise against messing with any of the wiring as that would now make it your problem and not theirs anymore. If you see butt connectors and crimps, find another shop to do the repair work.

    I have read that there has been a few, but don't know full details on them. If it was a true failure, or not.

    No, they are probably talking about these: https://www.amazon.com/Shrink-Solder-Sleeve-Crimpless-Connectors/dp/B01M1032A7

    I'm not a huge fan of them, but they do work when used properly. If they didn't get the solder to melt and flow completely that could be the source of your intermittent connection.

    My head end is flakey and has been replaced without solution. Toyota radios are generally understood to be “ok” but not great. Unfortunately getting all the integrated services to work in an aftermarket unit is complicated.

    I would check the harness behind the unit since you get both sides flaking.

    But I have simply given up trying to fix my radio and just use my Ham radio (which you don’t have music on while transmitting). My thinking is my decision to put in the factory JBL was a costly mistake not to repeat. Next time I will get the worst option available and throw it out as the dealer gives me the keys and install a full on system from Crutchfiels, if I can find one that supports all the steering wheel features and, more importantly, Bluetooth to the phone.

    I had a similar situation after I upgraded my speakers and added an amp. The issue is the aluminum wires that Toyota uses. They don't solder well with copper wire. My installer changed all the wire from the headunit to the speakers and amp to copper and I haven't had an issue since.

    Good luck.
