One of the reasons that we went with the DeLorme is that in its newer
versions it is actually very easy to use. When trying to find the
route, you can just enter the lat/long in the destination window in
virtually any format and it figures out what you mean and sets the
route. We do use it in the motorhome on the big dash but have a Jotto
Desk that we can put in and out of the toad (or any of the other cars)
in just a few seconds. On an articulated mount, the Jotto Desk can be
positioned to put the laptop screen in easy view of the driver and the
voice command function means that you don't need to be fiddling with
keys while driving.
