A53 car Bluetooth connection

[HerrTaffy]

Hi, 

I have an issue with my A53 phone and my car. I'm connected via Bluetooth not the android app. When I use the car to phone someone it calls but uses the phone to speak not the car. I have to tap the phone and select the Bluetooth device to use. 

How do I make he car the main Bluetooth device to use.

Cheers Greg

@HerrTaffy: While you're connected to your car, please try heading to Settings > Connections > Bluetooth > Tap the cog to the right of your car's system > Calls, and toggle this option on. You may also wish to consider utilising Android Auto via Settings > Advanced features > Android Auto, as this is specifically designed to provide an hands-free service while driving.

So I've finally found the answer to my question. The car doesn't have the android auto. I've found that the phone is connecting but using the phone rather than the cars speaker and microphone. I found that there is a microphone switch on the car display. This transfers the sound and mic to the car settings.
