You need to patch the firmware in gpsmap64 in order to use new maps.
And when that is done you could just as well surf around and find FriPro v5...
Strange that other unlocked maps are working like a charm for ex. Garmin TOPO Finland Suomi v3 PRO, Garmin TransAlpine v4 PRO and REGIO EESTI TOPO V1.7
