My 03 Boxster has a CDR 23 unit fitted. The manual says FM frequency steps
are 100 kHz. Trying to set a freq on mine the increment is 200 kHz.
e.g trying to set 107.0 it goes from 106.9 to107.1 and this continues throughout the freq range. I cannot find anywhere I can change this 200 back to 100..
Any help would be appreciated.
