One question I ask myself is if the FR 965 will have the same problems as the FR 955 in recognizing free third-party maps
I installed 3-4 different maps on my 955. Some of them I used befor on my F6 did not work at all and watch froze. Then some maps just disappeared, depending on how many I had installed. Plenty of free space. If I remove one map, another suddenly appeared again. This is a known problem with 955 since the release, search the 955 forum.
