Hi Paul,
Excellent!
I think you are correct - no immobilisation - just tracking and alerts. But at least it means there are now 2 or 3 ways to track the car: The Lexus app (for those with say post 2019 vehicles - when it works...), the ODB tracker/geofence and then the police, through tracker, can use the battery powered VHF tracker device too.
Of course we are all desperate to get the actual CANbus fix via this CAN blocker ECU....
Paul
