A:
I don't know about a vent-mounting, but if you're willing to sacrifice your CD player, there is a magnetic mount holder that I use and really like: "Scosche - MagicMOUNT CD Car Holder for Mobile Phones" (Model: MAGCD2 SKU: 5867869). It holds my phone really well, and if your CD slot is high enough you won't have to look too far down to see it. The mount is not hard to install or remove. You do have to attach or install a little metal plate on or in your phone to make it work, of course.
