OBDII Connectivity allows the device to be powered through the OBD port. That also means that it automatically connects when the car turns on. Unlike some products this is not tied to a vehicle, so you can use the same device in almost any car built after 1996. Connecting to your Droid platform or iPhone mobile device is as simple as pairing your device with a new Bluetooth connection.
Have a look at some of the applications listed below and you'll find out just how many uses this device has. It will save you time and money by monitoring the health of your engine so you can approach service proactively instead of after the CEL comes on. By clearing your own codes you can also avoid a costly trip to the dealer after performing your own maintenance.
