For me TransAlpine v4 PRO works in BaseCamp without problems.
In my EDGE 800 after unlocking with GIMGUNLOCK v.0.3 there comes up a message: "Map is not authenticated", but nevertheless, the map is shown in simulation mode on the device. Routing not checked yet.
According to my impression, there are less POIs and less information in the POIs (no Tel.-Nr. e.g.) in comparison to Transalpine 2012 Pro.
