Was just wondering if any one owned one of these and had any comment to make about it. How does it interface with the RioCar, PC, etc... I am consideriing purchasing one but was wondering if it was a necessary component even though I already own the in car units.

PS - Would like to mention that the Rio Central would be a slam dunk for me if it also played DVD's. An all around player to replace my DVD, CD, etc.. would be great and save me some space!
