Lowrance has completely abandoned the aviation line of GPS receivers and no longer supports Jeppesen updates for the Airmap line of GPS receivers. I personally called the company in Tulsa, Oklahoma and received absolutely NO support from the technical services. I certainly expressed my displeasure at the company decision to no longer provide support. I took my Airmap 1000 overseas and installed the international database and very recently returned to the US. Upon visiting the
LEI Extras I discovered I could not download an updated US aviation database. I'm unable to locate my previous US database file either to at least make some use of it again in the US for aviation. I called Jeppesen and was told they only provided the unformated aviation data to Lowrance whereupon the database was structured and formatted to make the *.at5 file to be read by the GPS. They weren't much help as they don't create the database file, only the data. Lowrance would not offer anything to allow users to continue to personally update the devices either.
Anybody out there have a copy of the latest Jeppesen aviation database file (JepAmr0706.at5) to send me. I don't know if I can get it to work on my SD card but I would certainly like to try!
