I recently hastily bought and installed a 2012 2nd hand USA region RNS-510 E unit loaded with 2015 Australian maps. But street names aren't showing and cannot be selected when entering navigation points and no routes can be calculated, although the map displays fine.
Is there a compatibility problem with this setup. Do I need to update the VAG com codes (everything else works OK). Can the firmware be updated with oz region firmware?
