I upgraded my Helix 5 Di for the Helix 5 Di GPS Combo which I received yesterday. I updated the software from version 7.520 to 7.730 via the Micro SD card. The upgrade was successful however sometimes when I turn on the unit it appears the one of the primary colors are missing as the look of all of the screens have a darker appearance. When this happens I also noticed that all of the settings revert back to the default settings. If I leave the unit on the screen seems to go back to normal after about a minute. I am not 100% certain but this seemed to start happening after I did the upgrade to the latest software. My question is can I revert back to the previous version 7.520? And If I can where can I fond that version to download?
Thanks
