So I decided to mount my Zune 8GB mp3 player in my car, since I have 74 miles of commute per day. I found that being that I had chosen the 8GB Zune, there were no real holders I could find that fit that player. After some research I found Proclip, they had two great features, 1, it's custom to your car, meaning no suction cups, and they are also custom to your device. It's a 2 piece system as shown here:
The mount I chose the center mount one of two made for the Mitsubishi Lancer:
I then Chose the device holder for the Zune 8GB, of which they also have 2 options:
The most impressive part of these mounts is that they are custom to almost all devices and makes and models of of cars. They also don't require many screws into your car. It fits between pieces of your dash.
If you want a professional looking mount that is easy to install this is your best option. Give them a try.
