Hi Justin,
I was wondering if you still have the same problem and whether you could find a solution to the problem. The same problem happened to me almost around the same time as you post your question here. Before going to dealer, I search the web if someone else had this problem, and I noticed the exact same problem with the radio unit/navigation unit had happened with the Lexus cars, and some Toyota cars ("they didn't mentioned specifcally about Toyota Corolla"). Here is the link to it

So I decided to take my car to Toyota Dealer and explain them the story, and after they gave me a 3 weeks appointment, I took my car there 3 weeks ago, and after 1 hour waiting, they guy comes back and say this Unit needs to be replaced, and told me you just went over your warranty by extra 5km. Anyway, I asked this is impossible, this looks to me just a Firmware issue, that could be resolved by flashing the firmware. Long story short, he basically told me this is what we are supposed to tell you from Toyota "You need to replace your radio Unit". Well, I don't know why Toyota doesn't take care of their own customer anymore.
Other approaches I took to fix the problem - but still no lucks
- I did unplug the batter for 5 minutes and plug it back and nothing happened.
- Search the forum and found that there used to be a way to update the Firmware ( you could make your own USB ) but the files were removed, here is the link [Can't send link due the being a new member, you can search it in the forum , use keywords Entune Audio headunit software update]
- I saw Josh Video, and I have to thank him for posting this Video, as I think after two months searching, I still have one option left before make a more expensive decision and go and buy a new unit or get a after market Unit :/ That shouldn't really happen.
Could you please update if anyone find a solution to this rebooting loop problem?
Thanks guys
