Thanks the unit only has right or left choice unlike my last unit it used two speakers.
Even techy at clarion was unaware that you could only use one speaker.
The blue tooth should come out of drivers side speaker.
Sounds like your left speakers are wired up to your right side and vice versa.
Simple to test, go to balance settings on stereo, switch to left speakers only, and if your right ones stay on, then speakers are wired up wrong.
Seems a bit daft the bluetooth only working on passenger side, you would think it would work on drivers side.
