Important note: All units that utilize the OBD diagnostic connection in the vehicle to perform software activation or other software settings can only be used in one vehicle. The OBD unit reads the VIN when used for the first time, thus preventing use in another vehicle. For this reason, OBD units are excluded from exchange or credit.
