Re: GPS Power

The routing features of the Quest woud be great in a car, but not really
needed on a sled. If you're going to use this on more than one vehicle, one
being a car, then I'd say you bought one of the correct units.

The 60C can be bought online for around $330 US, but it has no routing.
