...hooked up to a GPS receiver? Is there a way to output a GPS moving
map
to something like this?

No. There is not an aviation handheld GPS out there which will directly
drive a screen like this. You would need another computer to interpret the
raw data from the GPS and then draw the map on this LCD screen. There is
stuff out there like for IPAQ palm computers and such.


The price is certainly attractive... And -- if it were possible -- you
sure
couldn't beat the size of the moving map!

You might as well go get a used cheap laptop computer and display your
moving map there. But you'll have cables everywhere and the laptop screen
isn't readable in the sunlight. Just use the map on your GPS.
