I have a Garmin iQue 3600 (Palm OS) which I have had for over a year; but I don't use it very much.
It mostly sits in the cradle next to my computer at home.
So, I'm looking to sell it off.
It came with the car kit, so it has a car charger, a very good dashboard cradle that holds the device very well.
It came with a flip cover that covers the screen.
The cradle at home connects to a computer (USB) and an external power source (so it can be plugged in without a computer).
It also comes with the discs containing maps.
It is no longer available from Garmin, but here is a link to the Garmin description of the device:

I looked on eBay, and there are some that have sold in the past few months for $142, and a couple for over $200.
So, I guess I'd be willing to go with the $142, plus shipping.
