I’ve tried a few automobile GPS devices in the past and usually been disappointed, mainly by the absence of a voice command that talks me through directions before they are needed. I bought a Garmin StreetPilot C340 recently and have to say it is simply astounding. It’s plug and drive — you plug it into your cigarette lighter, wait a few minutes till it acquires satellites, answer a few set up questions, type an address into a touch-screen keyboard and hit “go”. It’s like having a perfect navigator beside you.
