Hella Gutmann identifies mega macs X as usable as a PassThru interface. Consult its PassThru installation guidance and the vehicle maker’s supported hardware and software requirements for the intended operation.
See Hella Gutmann PassThru devices.
Vehicle coverage, functions, vehicle-maker approval, operating system, driver version, subscriptions and security authorisation must be checked for the exact vehicle and job. Follow the vehicle manufacturer’s programming procedure and specified stable power supply. A J2534 interface does not by itself supply OEM software or guarantee every function.
