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 with
GPS speed which isn't as accurate as a paddle
wheel I'm sure but probably pretty close most of the time.
