Here is my problem. The software on my Garmin 2010C is version 2.14, current version is 5.9. The largest data card that can be used is a 64MB Garmin #101-10226-12 or -02, the software update is bigger than 64MB. All I really need is to be able to transfer data from the card to the chartplotter. Garmin no longer supports this unit and has no suggestions, has anyone had this problem and found a fix?
