This latest GPS tracking device from Navicom is small enough to be placed on a keychain, but features full-on GPS capabilities. The C-TRAC GPS Personal Tracker has unlimited GPS tracking/locating, an E911 emergency feature, and even a push-button concierge service akin to GM's OnStar (!!). Other features include a two-way speaker phone, programmable buttons for one-touch dialing, a USB port, and 256k flash memory. Each unit costs $480 if you get it directly from Navicom. The price includes an unlimited 1-year GPS service, which sounds like a pretty good deal. And it has a software interface that looks like Google Maps via some cheesy Hollywood movie.
