Concox OB22

The OB22 plugs straight into the OBD-II port and begins reporting immediately. There is no wiring, no dashboard removal and no installation appointment, which makes it ideal for leased vehicles, staff cars and any fleet where you cannot modify the loom. Because it reads the vehicle bus, it also surfaces engine data a hardwired tracker cannot: fault codes, coolant temperature and battery voltage. The trade-off is that a plug-in device is easier to remove, so choose it where convenience matters more than theft recovery.
