I know this is a old topic, but my problems seems at least partially new.
Bought a nuvi 205(t), updated the firmware, installed a SD card with maps.
Then things got weird. I can search for some Street names, while other street names are not found at all. (tested different routable maps)
Taking frikart.no for example i can find Munich with its local name “München” and it has no problem listing some streets:
But the perfectly displayed “Lothstraße”, not in the list and comes up emtpy on name search “Loth*”:
What exactly is going wrong here. Any advice is highly welcome
Edit: I am also having some weird rendering issues, something seems wrong, even after factory reset.
