I imported my 991.1 equipped with PCM 3.1 Nav/Radio from the US to EU.
Everything went well, navigation maps were updated to EU maps, language changed to German, etc.
The only thing that's not working properly are the FM radio frequencies ... it still seems to be set to US frequencies (only uneven frequencies steps):
Is there a possibility to change the FM radio region from US to EU somehow e.g. via OBD2 ?
Or does someone have the exact fields in PIWIS2 to be re-coded to do such a switch?
