Cnfhbr, at the present moment I thinking more about some other software platform to build my maps, instead of Garmin. If someone wants to make personal legal proprietary maps with locked (protected from export) data and expiry period there are good quite affordable legal software solutions for this. For instance, CarryMap by DataEast (this is not advertisement). For a very affordable price one can legally produce executable map files with locked and protected data with expiry date set for many mobile OS. And the technology to build these maps is much simpler than that for Garmin img ( GPSMapEdit + mp2shp + MPC, etc.).. I just go ArcGIS->CarryMap with all louts, topologies preserved. Of course CarryMap maps are simpler than Garmin (no routing, no 3d..).
