Hey all,
I purchased this unit for my 2015 Toyota Corolla S-Plus in December of 2020 from Amazon:

It has worked perfectly for me since. Maybe a handful of times YouTube or Sirius XM app will shut off - but over the course of 2.5 years owning it, this didn't bother me at all. I have never updated it or done anything to it.
Last weekend I had been driving for about 2-3 minutes. I was running Sirius for music and the unit abbruptly cut out and was skipping on the last note of the previously playing song. At this point, steering wheel controls were also gone, which made sense - the unit appeared to be off.
I got to my destination 5-6 mins later and attempted shutting off car and turning back on, but nothing. The unit wouldn't come on.
Yesterday I checked all relevant fuses and they are all fine. I probed the harness coming to the back of the unit and it is grounded and receiving 12v-14.8v both constant and on car start.
Pressing the RST Button and holding it, the buttons will light up / blink a few times but then nothing after that. I consulted the manual but it says nothing about how to use the RST button. It sounds like all you do is hold it for X time and the unit will reboot. I also attempted totally disconnecting all power to the unit and waiting about 10 minutes, same results.
I noticed there is an SD card in the side of the unit - is it possible that this holds the OS? I am wondering if something on the OS itself is corrupt or something along those lines, but I have no idea. Is it possible to do a software / reformat without the unit being powered up? Like can I just flash some bootdisk and attach it to the unit?
Also worth mentioning, when I pulled the unit out from the dash all the way, I noticed that my ground wire was dangling there. So I'm not sure if it became disconnected when I pulled the unit out from the dash OR if it somehow became disconnected while driving - if so, could that potentially be the root of the issue I'm seeing now?
Just wondering if this is salvagable, I really dig this unit.
Thanks everyone
