I am going to be going a different route on my backup GPS. If anyone is interested in a very lightly used Airmap 100 with all accessories, plus the bonus of "StreetMap" software (including marine/street and waterways databases), shoot me an email off board. Ebay seems to be selling them in the $150 range without the extra software, so I will sell for $150 with it plus free shipping. First Come, First Served. Oh...I bought a database update only a abit over a year ago I believe, so it is relatively current by used GPS standards, and Lowrance still does the updates via diskette.
