[CA] [CA11] Upgrading from SL70 to ev200 and E127’s

[markdd3880]

Hi Chuck
Back to the lake!
Just checked the firmware versions on the system and the ev100 and the I70s require updating. Looks like the ACU is up to date as I am attempting to solve the 30 degree difference in the onboard compass heading and that being displayed by the system.
Deviation is at 7 degrees.
When I attempt to update via wifi on the E127 it tells me no updates are available for any of the products but when you look at them on diagnostics they are indeed out of date.
Is it actually possible to update these devices via the mfd and wifi or does it have to be done from a card.
Many thanks
Mark
