I have the mobile ease and I love it! The sound quality is great and it is sooo easy to use. I have it installed in a nice place too, in the blank spot somewhat behind the steering wheel to the left of the center cluster (I hope I explained that right). The mic is installed at the very top most corner part of my windshield (not on the headliner or the plastic column next to it). If you look at the very top, there is a bit of tint and it is concealed by that.
My husband works at a dealer, so I am not sure how much it cost. He also installed it himself, so unfortunately I can't help with that either :wacko:
