GROM SmartScan(TM) Bluetooth OBD II Dongle currently works with Android and Windows phones and tablets only.

Not all OBDII Dongles are equal. GROM SmartScan(TM) Diagnostic Tool works on all vehicles with an OBD2 port. It supports most existing protocols, including CAN protocols. Check supported OBDII protocols under Specs tab.

By law all Petrol cars in the EU made from 2001+ and Diesel cars from 2004+ should have the OBD2 port located around the drivers area. In the USA all cars were forced to have this port from 1996 onwards, therefore some earlier EU cars adopted this before 2001/2004. For vehicles pre 2001/2004 owners should check to see if they have this port. 

GROM SmartScan(TM) OBDII scan tool will allow you to fix simple problems yourself. With SmartScan OBD2 Tool you can find out why your check engine light is on before visiting the mechanic.
You will be able to read and clear diagnostic trouble codes (both generic and manufacturer specific DTCs), turn off the Check Engine Light and display current sensor readings using your phone or tablet (with the appropriate app).
