"NAVIGATION / RADIO REBOOTS HANGS PROBLEM UPDATE"
Hi all! I have read more than a couple of threads on this topic. Mine is on 2014 Limited. Last occurrence was probably 8-11 times in my 10 hour drive from VA to Boston. Worst was I hangs right when I was crossing the Nj-NY through George Washington bridge where there's like 12 different directions to exit! Good thing I had my phone nav to back me up.
Anyway, I took the 4Runner to local Toyota service and although they said they don't have an official TSB that addresses the problem they uploaded a new software update. When I look at the receipt, it has the "T-SB" designation on it. Ill post the picture of the software update receipt so everyone can see and maybe use it when you talk to your local service centers for fix.
So far I used the Nav/Radio today after the update on my 60 mie roundtrip to work and no problems. I will update this threads if theres any re occurrence of the problem.
I have a 2016 4Runner (Navigation Unit) with a head unit that has constantly caused a headache. It started in 2017 when the XM tuner gave out. The dealership's solution was to replace the head unit with a refurb. I think back on it now and I don't recall changing the radio ID number with XM because I got into the vehicle and XM was already working. I got several months out of it and it started either freezing/rebooting constantly or just froze during startup and constantly rebooted. The dealership's solution was to update the radio. I then spent the next several months (sporadically) with the problem returning and the radio was updated to fix it. Now, in 2018 the problem has returned and has gotten worse even as I write this. I either get the constant reboot or frozen startup/reboot. It has gotten worse since the head unit on startup sits their with a black screen (backlit at night) for at least 15 minutes only to freeze and reboot. On average, my drive to work is 20 minutes and I get 3 sporadic minutes of actual radio usage. I have taken it to the dealership again and they say their are no updates including the map microSD card. Their solution this time was a hard reset which is a fancy they worded disconnecting the battery cable and letting it sit for 30 minutes. The dealership has done this 3 times and the problem has gotten worse. Now they want to have the vehicle in the shop for "who knows how long" so they can go over it with the Toyota engineer. This problem occurs with absolutely no bluetooth device connected at all, despite the dealership constantly asking me bluetooth related questions about the problem. I'm most likely looking at yet another head unit, making the 3 unit in 2 years! Is there anyone on here who has experienced this problem that has any kind of solution. I'm to the point now where I ready to rip the thing out of the vehicle and spend $1500 on aftermarket after I blast this problem to everyone involved including the BBB. I have listed some of the details below of what has been tried by myself.
- I have a standard Verizon Galaxy S7. I have used the bluetooth maybe 6 or 7 times in 2 years. Problem occurs without bluetooth connected. Also occurs regardless of having my phone saved in the radio or not.
- I have removed the radio's permission to see my contact and text message list.
- My phone has no special characters in the contact list or texts that would cause a problem (according to toyota).
- I have tried soft resets (holding the power button) to no avail.
- I have updated, reset every app on my phone including the operating software.
- The radio has the most current update and entune app on the radio and the phone is up to date.
- I have removed the map card to force the nav to reset.
- I have played with every setting possible in the radio and tried every combo I can think of.
- This problem occurs no matter what is actually being used on the radio. (XM, FM, NAV etc.)
- I don't use the nav regularly, maybe 5 times.
Toyota Has Done the Following:
- Replaced the head unit with a refurb
- Updated the radio at least 8 times
- Disconnected the battery 3 times
I have contacted toyota corp./entune as well. I have almost no faith they have a clue what they are doing.
If anyone can help, please let me know. Thank you in advance.
