I bought an e7d for the boat last year and after a few months the touch screen
was totally unusable at first startup, I would have to go through the extensive calibration to fix it. I found out about the recall
so i sent my unit in and got one back promptly but with a screw rattling around inside. Raymarine
was good to pay the shipping
to fix it. Just fired it up on the boat and they loaded lighthouse 2 on it. So far the major differences are there nicer data screens and it appears to calculate true wind
speed which isn't as accurate as a paddle wheel
I'm sure but probably pretty close most of the time.
