When I upgraded it crashed at startup. Then I deleted and re-installed and problem was fixed.
For commercial users & motor boats this might be a very good product. If you go from A to B.
But for me who sails in rocky waters among islands I very much miss detailed info on rock depts in shallow parts of the map. For me there is a huge difference between a 2m that I will hit and a 4m that I can pass. Lack of detail might be related to C-Map. More detailled info I get in alternative map products.
