I don't know how practical it would be mounting on the left. I have a feeling there'd be too much glare on the screen and I'd have to rotate the phone so much to avoid the glare that I wouldn't be able to see the screen then...
Either way, between the (2) req'd parts from ProClip, it's getting in the $50 range.
I'll position my phone to the right side of the center console and see how it looks (and feels). I have a feeling it will be too far away for my preference.
