I think you emailed Avmap and found this out already. Avmap stopped
updating that unit about a year ago. Apparently the datacards or the
programming machine had become so old that the cards wouldn't update
anymore. They don't even have any old datacards laying around anymore.
I tried to call another company that saves stuff like that but they
went out of business last year.
