I just picked up the Gen2 12 touch but i cant figure out how to upload the smf.exe files I havent recieve the insight chip yet but i have tried there demo and it doesnt allow me to upload any file but Sl2.exe files. Does that program not support side imagining? I can view the overlay playback on the unit so i dont see why it wound not work on the pc. Also do you know what the Xls.exe files is when at the end of the route it asks if you want to create a structure map? If you could please tell me what software I need, and how to get the structure scan files to playback on my computer. Thanks ive looked everywhere cant find anything about it I tried to install the sonar viewer from Lowrance but it doesnt seem to work on windows 7 any help is greatly appecated
