I recently bought a 2010 VW Polo and it had the RCD 310 stereo which I know supports Bluetooth. I’m almost certain my car doesn’t have the Bluetooth module since the car doesn’t show up on my phone. Some people say that the Bluetooth module is underneath the seats (or at least that’s where it would go) but there’s nothing there, not even a space for it to go. I have noticed that in the passenger footwell where the bonnet catch would usually be is a door where something could sit in, could it be possible that it would go there?
