XC90 2012 CarPlay and Bluetooth

[sugerbear]

Purchased a roadtop 8.8 inch CarPlay unit and ripped out the pop up RTI screen. It’s working amazingly well and means I have a relatively cheap CarPlay unit that can connect to my standard Volvo stereo (when I say “well” I have to twiddle the source knob to CD and back again to BT to get the phone to connect to the car, but it does work, otherwise the roadtop plays sound through its built in speaker).

So the question I have is that the car stereo and the roadtop should be able to connect via Bluetooth but the stereo needs a PIN for Bluetooth and it seems the roadtop unit doesn’t support PIN entry (have asked the roadtop co if a software update is coming but they haven’t responded yet).

So the question is.. finally.. is there way to remove the need for a pin from the standard stereo for Bluetooth (and if so how).

I’ll post some pics of the unit when I can work how to upload them.
