didn't try it yet but it arrived in good condition
Tested on my car and it working ok , the procedure to connect by BT is as follow connect the OBD scanner in the obd plug , switch on the BT in your device and check only if viecar appear in the list , but don't connect to viecar , open application in your phone , Viecar , torque , infocar ...... and go in the settings , connection mode , choose BT , and seach viecar , connect to viecar obd scanner, now you phone is connected with viecarobd , turn on your car no need the engine only display , and wait untill the viecar device is connected to the ECU , thats all , Enjoy!!!!!
