I've been stubbornly using paper maps and a compass up until now, and have decided these GPS things might actually be a good idea. I don't need it to play video, store MP3s or answer phone calls. I really just want it to show me a map, where I am on that map, and which direction it is to the next waypoint in my route. And be able to load someone else's routes. A nice bonus would be the ability to run the device on batteries, so I can use it when I'm not on the bike. I'd mainly be using it in Europe, and if the map offerings from the various brands happen to differ by a great deal I would definitely be swayed by a brand providing good maps of Eastern Europe in particular (reviews I've read of devices so far haven't talked much about the maps themselves). I've looked at a couple units by Garmin and TomTom, but so far they all seem to have a lot of additional features I don't plan on using (like bluetooth support, MP3 player, etc). Are there simpler units on the market I can look for? Or are there some very nice features I haven't considered which I should be looking at in a GPS unit?
