I've had many Pioneer head units in the past and they have all done this. I have a AVH-4200NEX in my Fiat and it reboots itself all the time. Most high end car audio manufactures have left the market so there might not be a lot of choices left. I would say, leave it stock as too many bugs can come up with aftermarket units. Hope you find the cause of the issue as your system sounds like it's pretty sweet.

 

Our resident Audio expert is @stigs_asian_cousin IIRC, he did a head unit switch when GRC first came out. But left many things to be desired. I don’t remember if he did anything with any other head units after that. Most people on the forum just leave the head unit alone, and improving sound other ways.

 

You're Bings customer! I'm the headunit supplier lol. I provided the complete kit for your install. He did reach out not long after your install was completed and mentioned it doing weird stuff. I sent over a complete headunit replacement and he also said it was doing the same thing. Last time I spoke with him, I mentioned to try and do a firmware update. That could be the only explanation to what both units were doing the exact same thing. I have about a dozen of these units installed in other GR's and haven't come across the same issues you're having. Have you guys tried any firmware updates? Bing is a super solid guy, I'm stoked you got to have him do your system, and I'm stoked to have been a small part of it!

 

Hi
Yes, I am over the moon that Bing took on this project. He is a Great stand up Guy and his craftsmanship is top notch. The build is on his Facebook and it is work of art (inverted woofers)!! and thank you for your help with the replacement head unit and harness.
The firmware was updated from 3.04 to 3.07 and the results are the same. At first I thought it may have been a iPhone / CarPlay compatibility issue so I drove the car with the phone turned off (even before I started the car) and every drive it will stop/freeze and reboot (many times) with any music source at any volume. The new head unit takes longer to reboot than the original
And something new it has started to do -- on first start the volume may not not adjust up or down from the touch screen or the steering wheel and I need to turn the car off and on again for the volume to adjust.
Going to try the new TY14 and see what happens.
Thank You for your support
Vinnie
