I think GPS's for vehicles are very handy to have. I just bought my 4th GPS, a Garmin 60CSx. This one is fantastic and the memory can be expanded to 2 GB. That means I can load the whole State (Texas) with detailed maps and not just a few counties. My old ones, I had to load up the area I needed before hand.
Paper maps are not much good unless you know where you are or have the knowledge to tell. The GPS will tell you where and in what direction to go. If Mr. Kim would have had one, he would have knew where his car was and in what direction and how far the town was that he was heading to. It might have made a difference.
I normally run my GPS in Offroad mode, because I want to know how much farther and how long will it take. "Are we there yet"? Turn by Turn is nice if you totally do not know the area or where the address is you want to go.
I'm not sure about this new GPS with the colored screen, but the others do not like cold temperatures. I tried to use one in WY one winter, but I could not see the LCD display unless I warmed it up inside my coat for awhile. GPS's like the Street Pilot are nice to have in your car, but it is not portable. The 60CSx does both, but the screen is a little smaller and is non-touch. What I do with GPS's, portable types are better for me.
Once you learn to use it and trust it, you will wonder why you had not purchased one earlier.
