Ive got it and use it with this
Bluetooth OBDII OBD2 Diagnostic Scanner, Scan tool check Engine Light CAR CODE READER for ELM327
Its abit of a gimmick if you ask me the fact that its Bluetooth means the connections not great and Ive never tryed it with fault codes
Its good for a tenna (buy the time youve brought the adapter and the pro vertion) but If you want something permanent and does the job properly buy a ScanGauge
used on a mk1 zs180
