Pairing a phone to a car

One thing I would add ... There should be a list of paired devices on the phone, If so it would be best if you "UnPair" any devices listed on the phone as well as the phones shown on the Car. To Unpair a device from an Android Phone go to Settings, Bluetooth and there should be a list of paired devices - at the right of each paired device is a "Cog" icon click on this and click on the unpair option, repeat for any other unneeded devices.

Sometimes paired items get out of sync and both sides need to be removed to re-pair

 

Uninstall Your Phone Companion App

Phone Companion refuses to pair with my Essential PH-1, I've tried all the steps provided by MS my last step is to reset my phone and PC biy I would like to uninstall Phone Companion first and reinstall it.

 

Pairing a phone to a car

Remove the device from the cars Bluetooth list. Restart your phone. Go to the Bluetooth settings on the phone and set it to Pair. Set the cars Bluetooth to pair, they should find it each other.
