transfer maps to new phone
on my old phone I bought some Kompass and some Freytag & Berndt Hiking maps.
I did backup them on the old phone and tried to import them on the new phone.
The Kompass maps seem to work. But the Freytag & Berndt Hiking maps through this error: only files in the same format can be imported in a batch
How may I transfer these maps to the new phone?
