Bought a new ultrex SI w ipilot link. It said I had to update to newest version to see SI DI and sonar. Used a formated sd card and did the default restore before installing the sd card it loaded the new version then restarted. After restarting it said something about being invalid and encrypted it ?
Any ideas on why and how to fix it.
It's a helix chirp g2n gps SI
