From the launch screen menu titled ROUTES, you arrive to screen menu titled Routes created by TS12 and yours if you do so. You have on this screen the possibility to Create Route whit globe button, and Edit Route whit wrench button. Than if you click Mojave Sub you have 4 choises with the possibility to Create Session with pencil button , and Edit Session with wrench button. Question: What is the difference or purpose between those two screens. What is the purpose of Editing the basic Mojave Sub Division while you have four divisions of Mojave. Also I have tried the Create Session with the pencil button and it does not work. Is my question can be answered with the 240 pages Instruction Manual. Thank you for your help. Guy
