There are two major types of these adapters： USB and wireless Bluetooth adapter
iCarus software supports both types (since v0.3). To select your adapter click "Settings" icon of the interface
and then click "OBD settings" button.
We highly recommend to use Bluetooth adapter - you can buy one in our online Shop. It is also included to the iCarus M2 Standard package
