Even with an outdated map, a good GPS system will be useful. You can still see if you have the right direction and how far you have left to go. (My old system couldn't display maps and play music CDs ... so very often i would listen to music and just get the limited infos ... still good enough for much of the time.)
Cellphones: Depends on the type of phone you use. I use tomtom on a PDA phone and that's just brilliant; but I guess I wouldn't want to bother with a regular phone and a mini screen, really. I like seeing the map ... |
