[CA] [CA11] Replace i70 with i70s?

[Srah1953]

Thanks for this. To ask the question a different way, if I attached the i70s to the exact same connections where the i70 was when it worked, will it automatically work?
The original i70 appears to have got water damaged when I was unwell for a couple of years and wasn't in a position to maintain the boat, although it has been suggested that the units are waterproof, but the backing was not properly sealed (by me).
Thanks
