Hi Lou,
Unfortunately, LXe requires a separate airport database installation that hasn't been available for many years.
However, SeeYou for PC can transfer waypoint files to the LX7007. They would be used as the "Turnpoint" database, not the "airport" database, but that is fine. The LX7007 supports waypoint files of about 600 points - if I remember correctly. SeeYou for PC can be used to open a current waypoint file and sort by distance, select the nearest 600 points, then save a file with those 600 points. Then SeeYou for PC can transfer the file to the LX7007. If you need, help, give me a call. I charge for support like that, but it should take only about 30 minutes. I charge $60/hour.
Best Regards,
