I used the Delorme software and GPS receiver for years before I, for some reason I can't remember, I switched to Microsoft Streets & Trips w/GPS) (Actually, it had somehing to do with buying itfor $10 at an auction). It has a pretty blue light in the receiver, but the Delorme software was far more accurate than the Microsoft. I was going to buy the Delorme software, but it isn't compatible with the MS receiver. The laptop sits nicely on the fold down console of the F250 on a sheet of rubbery non-slip shelving material.
