S21 and poor Bluetooth connectivity to car

[Caroline83]

Tech help needed please!? Desperately. I've just got a new Samsung Galaxy S21 and I can't connection the audio to my car's bluetooth. It'll connect for calls but not audio. So I can hear calls through the car but frustratingly can't listen to Spotify. I've tried pairing and unpairing. I've reset the networks. I've cleared the cache and data but it hasn't resolved. I'm completely at a loss as to what the problem is. It's worth noting that it HAS done it though. I've re‐paired the connection and it's just randomly connected. But the minute I turn off the ignition and turn it back on again it's booted me off audio and will only connect calls again. Please pass this on to your techy mates if you aren't able to help yourself because I can't stand anymore radio chat on my commute to and from work 😭 Thank you 🙏

Are you sure it's the phone ??

[Caroline83]

I couldn't say for certain either way. My old phone connected automatically without issue once it was set up.

I've even re-set to factory on my car.

@Caroline83: When the S21 is connected to your car, head to Settings > Connections > Bluetooth, and tap the cog symbol to the right of your car's system. Are you able to toggle on Media from here? If not, do you have a USB input in the car that you can try, to connect via Android Auto?

I've tried this. The toggles for Calls and Contacts are on but Audio is in the off position. If I try to toggle on Audio, it slides right back to off.

There is no USB input in my car. It's a 63 plate VW.

I've called Samsung tech support and been told to factory re-set my phone. I have no way of backing it up though without a storage device handy.
