Vehicle Bluetooth connection issues

[userKCOkg8Dkva]

This is the second S25 ultra I'm setting up they both have issues connecting to my car's Bluetooth. It'll connect show as that on both my car and the phones connected devices list but it won't stay connected it'll bounce back between the car and the phone so it's impossible to talk to someone. Android Auto which I love automatically turns on the Bluetooth so it's an issue. I have a 2019 GMC terrain SLT, IDK if that matters, Samsung IT told me to buy a Bluetooth adapter like for cars that don't have Bluetooth but I had, have no issues connecting my S23 ultra. Anybody else have this problem?

• Forget and re-pair the phone and car.

• Check for software updates on both the phone and car.

• Disable Android Auto auto-connect feature.

• Reset network settings on your phone.

• Test with another Bluetooth device in your car to see if the issue persists.

• If needed, consider using a Bluetooth adapter or reach out to Samsung support.

I've done all of those every single step you recommended. At this point it's in Samsungs court, I'm not overpaying I'll stick it out with the S23 ultra a while longer and I really love the 12 gigs of RAM too SMH

Recently upgraded from my s21 to an s25 and now android auto will not stay connected to my 2021 Honda Accird with wireless android auto. Once the android auto is paired to the car it works fine, until the car is shut off and turned on again. At that point it says it can't find any compatible devices and when I try to reconnect the phone it says the device us not compatible with Hands Free Link. I have to delete the device and pair it all over again. If I pair the phone fir calls only, not connecting the android auto, the phone stays connected OK. Nevef had this issue with my s21.
