As of January 2011, Raymarine will increase the warrantee to 3 years on all products purchased from now on. All that is necessary is for the purchaser to register the units within 90 days of purchase online at the Raymarine website. The URL is http://www.raymarine.com/warranty. That is a great deal in my opinion. When looking at new electronics, that could make a real difference. By the way, the AC Boat show is the 1st week of February.
