GPS-Buddy's hardware is a 12v adapter, shown above. The company also has a version that can be permanently installed in the car instead of the 12v adapter, if preferred.

When plugged in, GPS-Buddy runs on your car's 12v power. If the unit is unplugged, an internal battery can power the device for more than 24 hours. The device also can report if it is running on 12v or battery power, allowing the owner to remotely see if someone has unplugged the tracking device.

Information is collected every second, and sent back to the service every 60-seconds.

GPS-Buddy has a GPS antenna input, and a Garmin nuvi adapter. When used in conjunction with a Garmin nuvi, GPS-Buddy leverages the GPS antenna in the nuvi. Alternatively, GPS-Buddy can be used without a Garmin unit, and the an external GPS antenna used instead.

GPS-Buddy says they have been working with Garmin for some time now, and most nuvi models already have GPS-Buddy software installed. Connect the nuvi to a GPS-Buddy, and the Where To? icon is replaced by the GPS-Buddy icon, as shown above. The company says there's no special GPS software required to use GPS-Buddy, and that Garmin owners can continue to update their GPS units using the same firmware updates Garmin posts on its website.

The GPS-Buddy menu appears to have all the same functions of Garmin's Where To? menu, but adds options for sending and receiving SMS messages, ID'ing the GPS, finding local fuel prices, and configuring GPS-Buddy.

Once installed, GPS-Buddy reports on location, speed, and various other statistics, and can be used to send and receive addresses and messages to and from the GPS. Reports are viewed via GPS-Buddy's website.

Using the web portal, it's also possible to set geo-fences -- virtual fences that can be set to send notification alerts if they are crossed. For example, you could configure GPS-Buddy to send an email alert if anyone uses your car while your on vacation, or if your car travels beyond a defined perimeter. The software can also be used to send alerts if the vehicle exceeds a defined speed limit.

GPS-Buddy leverages its built-in GPRS connectivity to send and receive emails and short messages.

GPS-Buddies can be used for fleet or consumer applications, will be available in North America sometime around March. Pricing isn't yet final, but will likely cost between $300-$400, and will also require a monthly service fee.
