Thanks for the update John. Good work finding the issue with BT 5. Last year I bought Dual Sim version of the S9 plus first before returning for a single sim. Pretty sure the s9 plus duo wasn't BT 5....Anyway it seems that there are now 2 things to watch out for if you want to connect via RSAP. Sigh.
Nope, that can't be right.
Bluetooth 5.0 was also on S9 single sim, and those work without problems as premium phone on Volkswagen/audi/skoda cars
Something must be wrong with your S10, are you sure you got a single sim version?
RSAP is the most cool technology for cars. the car has internet for trafficinfo and other stuff, the phone has much better signal,the phone navigation app is not disturbed during incomming calls and your 4G is shared with everybody in the car
