Bluetooth problem.

Hello, so I’m driving down the road talking on the phone on Bluetooth it just suddenly disconnected from Bluetooth and would not reconnect, I get home and had to delete my phone then re pair, I’m thinking this is an iPhone problem hopefully. iPhone XS Max on iOS 13.4.1.

 

I loaded the latest iPhone update last week and 2/3 of my calls in the truck get dropped now. I've tried removing and pairing the phone but it didn't help. I have an iPhone 8 plus.

 

I had to turn off Bluetooth, restart my phone and then re pair phone to truck. Definitely iPhone problem.

 

Yup same thing is happening to me. After the update my calls just drop.

 

I have the same problem on the regular.

 

Called the dealership today. They will load Entune updates on Tuesday and I'll report back on effectiveness.

 

The update at the dealership didn't change anything. I spoke with Verizon and they suggested a Network Reset. The Network Reset seems to have worked. My iPhone is an 8 plus. Hope this helps.

 

This just started happening to me last week.

 

What does a network reset entail?

 

general settings>reset>reset network settings

Seems to have worked for me but YMMV.

 

Did a network reset, deleted and repaired the phone. Now it still doing it. Once the call is dropped, the headunit restarts.

lost.

 

Fixed!

Found the answer on a 4Runner forum.

Turns out the headunit’s memory is flooded when it tries to sync all the contacts (if you have a lot 200+) and then perform another task (phone call, gps) and it crashes and restarts.

Solution: Delete the phone, on the phone Bluetooth settings, turn off contact syncing, then re-pair it.

If you want to add numbers into your headunits 4 favorites.
Add those numbers to your phones favorites, and select “contact syncing” “favorites only” on your phone.




Hope this helps!

 

I tried your solution. Works so far. Thanks

 

One more addition to potential fixes if you are still having an issue.
Co-worker (F250 owner) said his phone calls started doing this all the time, but only on the way or from work.
Turns out his apple AirPods were the culprit. Deleting them from his phone (AirPods still in vehicle) and his issue was resolved.


I will say, I have also done this and the issue is gone.

 

I'm back to square one. Dropping calls again at the 2 1/2 minute mark.

 

Exactly where I was.

I deleted the AirPods from my phone and the issue stopped

 

I don’t have AirPods and have the dropping call problem so I don’t think that specifically is the issue. Maybe multiple Bluetooth devices paired to the phone?

 

My problem is still there as well, mine is usually the same spot on the highway I take home from work everyday, it will disconnect from Bluetooth entirely and not do anything. I have to wait until I put it in park, delete my phone on Bluetooth settings and re pair. It’s a massive PITA.

 

I feel you man. It is PITA and frustrating as the same time. I think it’s tundra head unit. My phone works fine in other car.

 

My issues began the day after I loaded Apple update 13.5.1. I spent 40 minutes on the phone with Verizon. We tried several things before we deleted the last Apple update. It seems that it is working well now.

 

Fortunately I have not had this issue (yet - knock on wood) but I do have another question. Is anybody else annoyed by the limited volume on Bluetooth calls? I listen to the radio on about 20, but Bluetooth calls are so faint, I have them turned up to 55-60. I have tried turning my phone volume up but that hasn't helped. Of course it is MUCH worse if the truck is hot and the A/C is blowing harder (and louder).

 

My issue started as well immediately after I downloaded the latest iPhone Update.

 

What iPhone do you have? What iOS version do you have now? I have an X with iOS 13.5.1, which I believe is the latest without getting beta versions. I am not seeing these issues.

 

iPhone X with 13.5.1. If anyone finds the fix that works, let me know. It is very frustrating to be dropping calls all time time and the headunit resetting.

 

I would try for a replacement under warranty.

 

Try to updating the software from below. After I updated the software, it seems like it working. I was on a called for about 5 mins and it didn’t dropped call.

This has never happened to me. Though I ve never owned an iphone...problem solved.

 

Deleting the link to my Airpods has worked so far. Crazy this is the fix.

 

Same problem again. Apparently the Airpods were not the problem. This is so frustrating!!

 

Also having this problem and it's seriously pissing me off. Toyota headunit is a piece of shit

Bluetooth and Alexa(BT connection) both drop after about 30 seconds everytime
