Having enabled ONLY the 2 OVERLAPPING maps (CN EU NT in internal memory and GR-map in external SD-card) I can Search and Route (this is done with the detailed GR map on ext SD-memory - CONFIRMED!!!) without problems or other conflicts. Not to mention that when I enabled only one of them Searching and Routing was possible w/o any problem AT ALL (only the EU map routes "MY CAR" through a pedestrian road -because the map is not updated- close to my house in Athens and I use this to identify which of the 2 maps is used for searching+routing when both are enabled, SMART EH?!! So when both are used the pedestrian way is shown as pedestrian way i.e. CONFIRMED that the GR-map on the SD-card is used/takes PRIORITY !!!!
After a 2nd thought, perhaps catyman is correct (when both overlapping maps are on the same memory - external or internal)
