I've got the new Lakemaster MN 2.0 chip and the Lakemaster Contour Elite Software. I uploaded all of the waypoints tracks and trails from my unit into Humminbird PC. I then studied a single lake (Medicine) and identified several hundred targets (waypoints) and about 30 tracks (Lakemaster has you create Target Areas using tracks). I then exported the lakemaster data to Humminbird PC and merged with my existing data. IN total, I had about 1900 waypoints and 51 trails.
I deleted all data from my 797, my interlink and my 997 (multiple times) and loaded my data to my 997. When I would turn on the 997, the unit would crash and reboot. I then went back to Lakemaster Elite and reduced my targets to about 200 and deleted ALL of the trails. I merged the data again, deleted all data from my hardware and then uploaded again. Same result.
It wasn't until I only loaded the 200 targets(waypoints) for Medicine Lake that the unit finally performed ok. It behaves like a memory limit issue... Screen painting with the Lakemaster chip on my 997 is EXTREMELY slow!.
