As you said I installed the BC v. 4.2.4 and when I insert a sd card with this map on it in garmin folder the BC recognises this map (only this map and poi map). It is little bit strange because I had there also my other maps like Slovakia topo 2 and Slovakia Roads6 and NT Europe and it recgonises only these two maps Slovakia Topo v4 and Poi.
And also if I want to insert routes or trackpoints in BC into this map Slovakia Topo 4 which si on the SD card then this option is disabled. Any sugestions?

Plus the function BirdsEye can by used on this patched version of BC or it is only for those who have their accounts by garmin. Because it asks if my device is registred by garmin and after it discovers it is not it just generates the basic pixel map with no functionality to transfer it to my gps device, just asking, thanks.
