Delphi XM "Roady"
Here's a nice close up of the Roady. I especially like the small size, 30 presets, adjustable volume, and the fact it doesn't need any other electronics (ie: amplifiers, satellite decoders, or tuners.

Faults with the Roady include:

Small buttons are hard to use with heavy gloves.

It is not waterproof (so far none others are either)

Mounting bracket is flimsey.

Limited number of lines of info truncates artist and song titles.

It interferes with my Garmin GPS's satellite reception.
