Best mount

What add ons? I like Pro Clip for small things like iPod, phones etc.

 

For my Sirius receiver, I put some velcro right below that little storage door on the bottom of the center of the dash board.

 

I used velcro and mounted my XM receiver on the carpet in front of the storage door in the center console. You can see it here. I use a remote to operate it.

 

For larger stuff RAM makes super mounts. Used in airplanes, motorcycles... and even my own cars!
