So i was trying to input a simple route from KBOS to KALB vis GDM. Entered all of my data, activated it but the exec button did not light up...so when i try to go to PROG or LEGS, nothing works...is there a beter tutorial han the Flight Management manual tha came with the plane or can someone direct me through some troubleshooing? Akso, I would love if anyone knows where you can get a start-up procedure that also has illustrations where the switches and buttons are you need to push/turn.  Thanks :(!!!
