I have a complete system with Cerbo GX running 3.70 24&25 in my RV. Yesterday my system lost connect with the wi-fi. When I returned to my RV and went into the Cerbo settings via my Touch 70, I went to the wi-fi page. I was unable to enter a password. When I touched the rectangle to prompt the keyboard to appear nothing happened. The system appears to be working fine otherwise. I attempted to revert to version 3.70-24 and still nothing. I also downloaded a new firmware version onto a thumb drive and attempted to reboot via this thumb drive and nothing………
