I'm having more problems now, actually after the last update or upgrade the system has been taking longer to show charts or the fish finder. Sometimes when I go to the home screen and choose an icon either charts or fish finder the system freezes where I can't scroll across or down. Then it finally decides to open charts and the hour glass/Timer shows three times and only half the screen shows up. Finally I get the whole screen and try to zoom in or out and stalls again.
I would like to delete the last upgrade and go back to the previous, is that Possible? The new one starts with 19 not sure the rest of the ID, don't want to search now afraid i might loose this post. I really don't want to send this unit to the repair center and wait a month, is there an exchange program/
