Got mine. Not too bad. It doesn't block the screen that much (if the cd mount screw is up). It blocks some of the radio controls, but it's not too bad.
The only thing I was a little disappointed in was attaching it to the disc drive. You have to really tighten it, and you can hear the plastic bent. I thought there would be felt or something on the attachments.
All in all, definitely a great $20 phone mount.
Couple this with the Waze app for the iPhone, I don't even miss not getting the nav with MFT.
