Infotainment troubles

My infotainment system seems to be stuck in a loop. It comes on when I start the car, starts to load then the screen goes black and it starts loading again. Seems to be an endless crash and reboot.

I shut the car off and let it sit about 45 minutes. Tried restarting with same results. Oh, and the radio plays. I can adjust the volume with the center knob, but can't with the steering wheel controls. And I can't change the station.

Anyone else have problems?

Oh, and I don't know if it is related, but a few days ago my phone stopped staying connected. It would connect, import contacts, disconnect and then endlessly repeat. I finally just turned bluetooth off on both the car and phone.

Perhaps there is way to Boot it back to the original setting. Other than that a new unit. Good luck with it! Let us know. Sorry for your troubles)-:

I disconnected the negative battery cable, let the car sit for awhile, and reconnected the cable. Infotainment system seems to be working again (haven't tested in the "real world" only in the garage). Still having issues with phone connectivity though.

Have you gotten into contact with your dealership yet?

I find it funny how the solution for so many electronics problems is, "unplug it, and then turn it back on again."

Sounds a bit fishy... I recently stumbled upon a site which has info on the CMUs. Try getting the latest firmware package and reinstalling it into the car. You will need the files, and a FAT32 formatted flash drive. Try popping it into the USB with the car turned off and start it up. It should pull the files as it boots up and re-update the firmware.

You can find the files here:

Let us know how it works out for you!

Thanks for posting that, should be easy for just about anyone on these forums to do unless its someone not good with tech.

Should be part of a sticky.

Good info phozzy! The infotainment system has been working just fine since the battery unhook. I suspect the connectivity issues were on the phone (Samsung S6) end because I'd get an "unfortunately bluetooth has stopped working" error on my phone. However I can't explain why it worked perfectly for 2 weeks. So I paired and connected my phone to my wife's Avalon with the same results I get in the iA, phone connects and disconnects ad nauseam. I'd basically given up on having bluetooth in my car and for the last week have been listening to music from my phone via a cord plugged into the car's AUX input. Then last night a system update came through for my phone. Downloaded it and installed and now I have bluetooth connectivity in BOTH cars again! Keeping fingers crossed it continues to work.

Had the eternal boot loop issue on my 2016 Scion iA. Found a CMU unit on from a used parts dealer on eBay for $115 and directly swapped the entire unit. Definitely plug and play! Worked immediately on boot up. Part number is: DD1B 66 9C0A - Have the bad unit and was told by the local Toyota dealer that they no longer purchase new ones when replacing, but rather purchased refurbed units from a third party. Wondering if my bad unit has any value to such a vendor...??? Anyone know of a refurb vendor that handles these parts and might want to purchase mine to refurb?
