In another post I stated that I had a question about my hummingbird 899 si graph.
The answer as I found out and have accomplished is as follows:
Press Menu Twice to bring up main menu
scroll over to Setup using the 4 way cursor key
cursor down to user mode
change user mode to Advanced
cursor down to Local Time Zone
cursor left or right to your correct time
Hopefully if this happens to someone else this will give you some more help with your hummingbird SI.
