Well PND isn't listed which is DAB. What we need is the same again for a standard satnav ZN1 with DAB to study. Whether it's missing a unit or whether it's under software control and you just don't have the DAB aeriel wired in the back. The manual above shows the dab in at the back of the unit, strange that you would specify the unit by two codes. So may be it's under software control but nothing is connected into the back of the unit or its like Sky TV it's there but not working since you didn't pay for it. Little bizarre that they run a cut down hardware variation of the unit.
You have the 8ZH aeriel the same as me so that is the dab aeriel. I can't see they would wire the car differently, too much hassle.
Here are my codes but I don't think they use the PND code against the ZN2... That's why we need to see someone else's codes now with DAB and ZN1. In the last resort go into the engineering menu of the infotainment unit when you have the obdeleven and carefully looking around to see whether there is a DAB toggle.
