Mike, the solution I'm using for just the problem you are talking about,
being able to see things in the cab while driving, is a pair of glasses with
progressive lenses.  Makes the dash and things on it come into sharp focus.
But, if you don't already wear eyeglasses then that idea won't help.  I do
have a GPS with the 4" screen, a Pioneer, and I can see it fine when mounted
on the dash.  BTW, I haven't mentioned the Pioneer unit in the current GPS
thread because I'm totally unimpressed with it, especially the software.
Fine in town but the database for minor things like parks and camp grounds
is pathetic.  But the price was good!
