Remember that the Rio Car will plug in just fine at home without a docking station. Those who make home docking stations are only doing it to make it look snazzy and make it slightly easier to plug in.

To make a home docking station, you mount a car sled inside an attractive box. There's actually a lot more to it than that, but my point is that you have to use a Rio Car docking sled with a Rio Car, it's not a generic thing, it's very proprietary and specific.
