The tite says most of it. My phone has worked in my car via bluetooh since I got the car in 2016. Suddenly, it has stopped working. Not entirely, mind you. The phone still pairs with the car and I can still pay music over bluetooth. All my contacts are still there, it's just that the car displays "No Cell Service" but when I check the phone, there is plenty of signal strenght and I can make calls from the phone.

2016 Toyota Tacoma, iPhone XS. This problem just started on Friday and I've briefly troubleshot it by unpairing and re-pairing the phone, rebboting the phone, rebooting the car stereo unit.

Just checking to see if anyone here seen this type of behavior before? Any advice?

Thanks

ETA: I've googled it but didn't really find anything helpful.

Any recent updates on the phone?

Thanks for the reply. The phone has the latest updates but they were applied long before it stopped working. It worked on the way to work Friday morning and when I got of work and back in the car it didn't work.

I would also have suspected updates and software conflicts. I see that doesn't seem to be a problem, but there could be a problem lurking in some other app that changes a setting, etc.

Maybe your car's computer needs an update. I had some trouble with my Mazda talking with Android, and an update to the car's computer cured the problem.

Delete from truck and re aquire. I have an XS and only had to re do once so far. Mine had lost it's pairing. Mine is on a 2012 Lexus CT200h.

The phone sounds most current, the vehicle not so much. See if there are updates available for the vehicle. They can get a little flaky with wide generations.

The update being needed was my experience w/ 2013 Camry, phone was older. Dealer swore it was phone updates and not the car, but it took several weeks of various delete and retry before they would order an update memory stick for the car. That worked.

This works for Android, probably Apple as well. Power off and then restart your phone. No workie, delete your vehicle from your bluetooth on the phone and re-pair. Still no workie, then delete the phone from your vehicle, and re-connect.

Its something to do with Apples BT, it's a bit flaky with some non apple BT connections.

My Plantronics office headset has triple connectivity, Voip, hardline or BT. Whenever I leave the office with the phone and get out of BT range when I re-enter the office its a crapshoot as to if the Apple BT will see the plantronics unit. Sometimes I have to tell the PT to reconnect to the BT and it will take a few attempts.

iPhone BT does the same with a BT headset, and with a standalone BT speaker I have, you never know if it will connect, in the case of the Amazon speaker it stopped connecting for over 6 months, would'nt pair no matter what.

Does it on my Harley as well, slow BT connection or it connects right up. Generall going to the menus and forcing the connection works.

Thanks for all the suggestions. I ended up having to delete the phone from the car,and the car from the phone. After adding them both back to each other things started working again.

Yep, my brand new 2017 Outback would mute the front speakers for about 5-10 seconds, three or four times a day. The dealer didn't have a clue. Over time, they replaced, the radio, a module and the underseat amplifier. They wanted to pull out the dash to replace the wiring, when I said NO. I knew if they did that, I would never get rid of the rattles. About this time, I noticed, that the muting was also what happened, when I got an e-mail or a text but without either . Again, the solution was apparently to uninstall and reinstall the phone. Now, if it acts up, I uninstall and reinstall.

Thumbs up!

You might have a bad bluetooth module. I had a 2014 Mazda 6, it had to be replced 5 times in that car

I just started having issues the other day when I updated to iOS 12.1. It was fine with 12, but 12.1 caused an issue (just came out a few days ago). The music would work, but would not show the details on my cars screen. Also text messages stopped working.

I deleted my phone from the car, deleted the car from my phone, and repaired. Good as new.

I have to do this a couple times a year in our Camry. The system Toyota uses is not the best. The GPS maps is junk.

happens on androids also. Googles play services is known for fudging up apps, then they comeback and patch all the issues. 3 weeks later issue a new GPS release and restart the patching process.
