I spoke with the Garmin rep at the Sportmans Expo. He said that starting in Feb/Mar there will be an update available for at least their Echomap users that combines Navionics and their existing maps to create what he calls "best in the business" mapping. I expected this to happen since Garmin purchased Navionics. Either way, he said if you have an Echomap Plus from last year, you'll get a "free" update to the new system. I think it's called "Lakevu G3" vs "Lakevu". He showed me the differences on the screens at the show and it was significant on the mapped lakes. I guess more lakes with 1' contours. I'm not sure if it'll increase the number of lakes mapped or not. I didn't ask about the offshore differences.

I'd post a link, but I can't yet...
