OP welcome.
There are loads of features of the car that are appealing, but ultimately this comes down to choice.
Speed comes to mind
amongst others.
In regards to Bluetooth. The best way I have personally found is to leave the music streaming and just get out the car and lock. Go about your business. Come back and get in. Within 30 seconds to a minute. Your music will be playing again. 😆
Note: Just make sure you do not end the process on your phone. If you do. Get back in the car. Wait for complete Bluetooth connection and then just hit play from your choice of app.
By the way, what handset are you using?
