I have what I think is a Mark 2 or 2a (how can I tell?) with a 20 gig disk and I'd like to sell it to someone who'll actually use it. Here's a picture:

Included is the unit, an original Rio remote (needs a battery), the install CD, the original manual, a car sled, and an old-school db9 serial cable. No power adapter, but those are easy to get.

The About screen says it's running version 3.00-alpha3.

If you're interested, let me know!
