Thread: Humminbird & Navionics Maps

What you do is run the map card in the unit till you are ready to do a recording or snapshot. Then you swap cards(mapping with a blank) Do the recording and when done swap back! Make sure you push the lock tab too lock on the map card so you don't accidentally record or write anything too it and screw it up!
Way points and tracks will stay in the unit till you do a " export all Nav data" or a "Save track"
If you are just marking waypoints and not takeing snapshots turn off the record feature so it wont write or try to write to you map card!
This is where the 900 series has an advantage! 2 card slots!!
Good luck You will Like it!
