[CA] [CA11] eS78 freezing after upgrade to LH III, charts not showing after downgrading

Welcome to the Raymarine Forum Gregg,

After populating the microSD memory card with the raymarine_atom-3.8.105.upgrade.iso file and then updating the MFD's software, this microSD memory card should be removed from the MFD's memory card reader, the raymarine_atom-3.8.105.upgrade.iso file should be deletedfrom the microSD memory card, the ray_mfd_AtomCartographyRX5v1_22.upgrade.iso file (contains the base word maps for Navionics, C-Map, LightHouse, and Weather) should be copied to the microSD memroy card, the microSD memory card should be inserted into the MFD's memory card reader, and finally the MFD should be commanded to check the card for updates. After the updates have been completed, it would be recommended that the MFD be commanded to perform a Factory Reset (HOME->SETTINGS->THIS DISPLAY->FACTORY RESET).

Finally, should one not find the performance of LightHouse 3 on an eS/gS-Series MFD, then the MFDs software may be downgraded to LightHouse II v19.03 as long as the system does not additionally feature an Axiom/Axiom Pro/Axiom XL MFD. As with the recommendation to perform a Factory Reset when upgrading from LightHouse II to LightHouse 3, it is similarly recommended that a System Settings & Data Reset be performed if downgrading from LightHouse 3 to LightHouse II.

BTW - the release of LightHouse 3 v3.9.x may occur as early as Monday or Tuesday of next week. Accordingly, should you not be using the boat this weekend, then you may want to wait for this update rather continuing with this process.
