The Automatic Link is a Bluetooth 4 device that uses your car’s OBD (on-board diagnostics) port found in all cars built on or after 1996 and a connected cloud service The ODB port is generally used by auto shops to diagnose issues and get information from a vehicle’s computer, but it can also be used to gather additional real-time data like fuel levels and a car’s speed.
Once installed the $70 Automatic Link device takes this sensor data and then adds a few layers of additional intelligence and features on top. Have you been wondering if that check engine light that is on can be ignored for a little longer? The included app helps you decipher that code and offers up suggestions on what to do next (And even clear the light yourself in some cases). A built-in accelerometer detects if you have been involved in an accident and if the impact was severe enough can report the crash to emergency services with your name, and current location. Other features include helping you track down your car in that airport parking lot, and dishing up trip details on your driving (rough braking, rapid acceleration, etc) and gas mileage tracking.
