The device will not pair with my car.
This is common and a rule of thumb, if you have a high-end end car, you will need a high-end phone. For example: A low end Mercedes does not pair with low end phone and in some cases not even with an expensive phone. Many car manufacturers offer a very limited list of compatible phone models. If Bluetooth is very important to you, it’s best to check to see if your car is compatible with the phone you’re interested in using, before the frustration starts building. If you have a super car, well, some just don’t have Bluetooth. Throw the phone in the boot (if it has one) and enjoy the drive! If your phone does not pair with your car, there are other options.
- Bluetooth speakers
- Bluetooth earbuds
I have to restart my phone every time to get it to connect.
Turning off Bluetooth Scanning, will usually correct this problem. This feature is buried in Location > Improve Accuracy in an advanced portion of the menu in Android. Bluetooth Scanning is not needed to connect to/or pair to a device. If you are still having issues, forget the pair, restart the phone and pair again with the device.
Bluetooth drops connection.
Several factors can cause this problem.
a. The Bluetooth radio is failing. Turn it on, does it stay on? Do the same with WiFi, does it stay on? If they turn back off right away on their own, the phone may have experienced a hardware failure.
b. Too many devices connected. Depending on what Android operating system you’re on, age of phone, and phone’s processing power, you may have too many devices connected. A computer usually can handle 7 connections. Some say limit it to 5. For your phone, best to keep it as simple as possible. If your phone is dropping connections, eliminate one at a time until all connections hold. Now you know what the maximum is for your phone.

Another thing to consider is Android Auto. If the car is compatible it will work with Bluetooth. A USB connection is an option on phones that are not compatible with your car. Beware that some streaming apps will not work unless the phone is compatible with the car’s system.
