Thanks for the information. I don't think I can use the older method since I'm on Windows 11 and the browsers are not compatible with that older software. When I look on Garmin's website about the driver, it says: "The light will be an amber color by default (this is normal), and will turn green when a card is inserted and is being read by the programmer." Unfortunately, the light just stays amber. I don't think it's the card since it works in the GNS 430 but it has not been updated in years. The card is silver. If the card is bad, I guess if I purchase another card (which I was planning on doing anyway), it may work with that. Otherwise, maybe the Garmin reader is bad. I've seen other reviews that say it doesn't recognize the card but never read where they have found a solution. I just don't want to keep going down a rabbit hole that is not helping. I'll try Garmin support next.
