I have had my Airmap 500 since last January and want to get my first
database update. Checking the Lowrance Extra's Website I find that since
September LEI requires installation of Microsoft Net Framework to
unlock Jeppesen Database Updates on the Customers SD/MMC card. After
6-hours to download Microsoft Net Framework 1.1 (About 24Mb) on my
dial-up and then another hour to download the Database, I tried
unsuccessfully to unlock the database on the card. The GPS does not even
see the Aviation Database. Tried three times at $35 a pop on my credit
card. Lowrance says they are looking into it - since Saturday. They say
nobody else has had any problem.

Any pilots out there that have had problems downloading/unlocking GPS
database updates from Lowrance?
