Do I have a defective Entune unit?

That doesn't seem right at all. I would go back to the dealer. Mine has never done that. I've had it since 2/28.

 

I've had mine for about two weeks now and today it rebooted several times during a 25 minute drive. Are you still having your issues or did you discover what was causing it? Wondering if it's a simple fix or if I need to take it back to the dealer for a repair or new unit.

 

Mine is doing this and also forgetting all of my voice command training and asking me to do it again. Maybe @Prius Team can help with stopping our systems from resetting on their own. My local dealer was no help.

 

I had the same problem that you described with my 2016 Prius Four. I visited my dealer but it took over six months for Toyota to create a software fix to repair my navigation system. More info on this and other 2016 Gen 4 electronic issues posted here: Did Toyota delete the mph/kph selection in the speedometer of your US 2016 Prius?

 

I have a 2015 Prius 3 and my bluetooth/Entune System has never worked. I was told by Toyota I had to have WiFi off on the phone when I get in car. I pair with car, try to make a call and it may or may not go through then No Bluetooth Connection pops up. I was told to turn car off, open and shut door and try again. Dealership has not been able to fix and of course you sign a service completion order before you can get the keys to your car ONLY TO FIND OUT IT STILL SAYS NO BLUETOOTH CONNECTION. I'm exhausted over all this nonsense. I've made 15 payments and also after accumulating 2 1/4" liquid in DampRid found i had mold in the radiator core. It cost me $130. It is not covered under warranty because mold is an environmental issue. Honestly folks, this green car has been a nightmare and I hope you never experience any of these problems.

I am having the same issue, is there a fix for this yet?

 

Mine rebooted multiple times on the drive to work yesterday. Nothing like using smart phone for guidance and you don't realize there is no sound being sent to speakers. I finally turned BT off on phone and used built in speaker.

 

I'm coming to the same conclusion as you. I don't have Nav or engine on my UK Business Edition, which is similar spec to your three, but my Nexus 6 has two good front facing stereo speakers. BTW, I'm using Waze or Google maps for the nav.

 

I had some occasional issues with my head unit and deleted the entune app from my phone. Then I had the dealer "reflash" my system. When I reinstalled entune everything is good.

 

I think I fixed the issue , for me it was the text notification (the one that pops up in the middle of the screen). I switched that off and haven't had it crashing since.

 

i had same problem deleted paring on phone and car then shut both off for a few mins then turn both on and repair
when phone asks u to allow text messages u must cancell that.then bluetooth will work fine on phone,i di it and works great.amazing a simple fix for all that frustation.

 

There's a lot of discussion about reboots in this thread. In my case, the dealer's solution was to replace the head unit. After the replacement, I haven't seen any problem.

 

there have been several firmware updates released for the Entune system to fix random reboots. The dealer flashed the latest update on my car in February and I haven't had any reboots since.

 

I can not get the Bluetooth to work with music and my iPhone. They told me I needed a new radio. Yesterday they put in the new radio and the Bluetooth still did not work. I knew replacing the radio would not work. Now they tell me they have to order a module and that will fix it. I have my doubts.

 

Not being a pro in regards to this, it would seem that the software in the Entune units in your cars were outdated when they were sold. Meaning, they needed to be updated with current software versions. It seems this is an issue specifically with Toyota cars. If it happened to me, I would insist on an update for the unit and if that doesn't work, a newer unit. Sorry that all of you have had head unit issues. Mine has worked fine for me. But I have a 2015.
