I would guess that it is not an original factory-fit one, and no changes have been made to the ISO connections.....
Fitting one in a car that did not have one ex factory, requires addition of a switched +12v supply on ISO A4, and to stop odometer from blinking this supply needs to be switched on via time delay switch about 4 to 5 seconds after ignition on.
You probably currently also don't get the trip info....
