Finally made time yesterday to run the update process as described. Everthing seemed to go well until after being directed to remove flashdrive and pressing the ok prompt. The screen went black and i waited at least 30 mins for it to boot back up. It did not, so I powered it off in another 20 minutes. The unit was connected to the nmea2k network at the time, with no other systems running. This am got on board, flipped breaker power on, went up on bridge pushed power button and still black screen with a audible humm coming from MFD??? Can I reboot or perform a factory reset with no home screen? Should unit be nmea2k connected at attempted time? Thanks in advance for any help!
