Engadget just gave some interesting information about some GPS units which act a bit differently. These were originally spotted by the Inquirer at the Computex trade show in Taiwan this week.

BT-318...a Bluetooth GPS module from GlobalSat which has an optional GPRS modem that’ll let you get online with your PDA or laptop (as long as they have Bluetooth, too). The other is Aqik’s new GPS locator for automobiles, which comes with a built-in GSM cellphone so that if your car gets stolen all you have to do is send the locator a text message and you’ll instantly get a message back with its exact location. And since it’s also a phone you can even secretly call it up and listen in on the thieves enjoying your automobile.
