[CA11] C80/ DSM-300 Software Update Issues

[rpdeines]

C80 classic display with DSM-300, I was upgrading to V5.16 and everything was fine until I pressed reboot which resulted in the blue screen. I turned off the power, restarted and it turned on fine showing 5.16 version at startup. Will the upgrade work fine? It seemed to function fine on the trailer and I haven’t tried it on the water yet.

I tried to upgrade the software on the DSM 300 to 4.20. I tried to select bootloader 5.18 using the down arrow and got the blue screen again. Shut off, restarted and was able to use the up arrow to finally select bootloader, but it hung up at 50% and showed failed (exactly how the instructions stated in a note but didn't say that it would be fine or what to do). So I continued not knowing if the bootloader was installed and proceeded to install 4.20 where I would get the error message of failed to install. What should I try? Or just ignore the upgrade? (I’m using the installed cable for install unless I need another cable)

FYI, the compact flash card is 512 mb and I can archive and retrieve my waypoints fine.
