I like the Garmin nuvi line. The screen auto-adjusts for day and night, but can be set manually. I bought it with North America pre-loaded, then bought Europe as an extra. Later discovered it would have been cheaper to buy it with Europe pre-loaded, then add North America. When I finally read the on line owners manual, I discovered it could do a lot more than get me from point A to point B. Among the optional accessories is a language translator with voice. The nuvi also accepts jpg and mp3 files. For leisure travel without a computer, this means that I can scan word documents (with stuff like addresses, hours, recommended must-sees, suggestions from FTers), save them as jpg files, then zoom in and read 'em right on the nuvi. Some models have bluetooth capability, but of course they cost more.
