h-bird 597 hddi help

after i updated, my unit sticks when i try to go to GPS screen. i can only switch between DI & sonar views without trouble. any suggestions?

thanks

I would first restore factory defaults...

If that doesn't help, you may need to revert back to your previous software version and then reload a fresh copy of your newest version from HB and try the update again...

If you do not have a copy of your previous software, you will need to email Greg telling him which version of software you need...
