Hi,... i fitted my car whit a rearview miror whit kompas.
noui have a problem with the readouts.
when i drive north the mirror indicates "SW" i ink this stans for South/west.
do i have to calibrTE THESE mirors in any way.
it's a miror out of an E90
on the bottum site of the miror there is a smal buton(looks lie a sort of reset button)
when i push it it gives a readout in the numbers 1 to 15
what do's these numbers mean.
anny one now
