I have installed the 123Tune + (great product, makes the car run really well) and can connect using my Android Mobile Phone via the App using Bluetooth. However, I have an Android Head Unit (Android 10, Bluetooth 5.0) in the car that won't connect. Please see image. It says 123Tune + wants to turn on Bluetooth (even though as you can see Bluetooth is already on). It seems to recognise the distributor (I assume that this is the %1$s that it wants to pair with?)
When I select Allow, it says "Turning Bluetooth on" but does not connect after that.
