Hmm. Their website at http://www.lei-extras.com/store/search.asp shows
current aviation database updates for the Airmap 300 available for 75 $
(single update, subscription is 61 $). Not sure what the problem is.

My 300 will no longer recognize that -- or any other -- database.

Without even looking at it, Lowrance diagnosed it as a "chip" problem. It's
apparently a very common problem with the 300.

They told me they can no longer obtain that particular chip. Thus, the 300
is orphaned.
