Their "BirdsEye Satellite Imagery" is very much out-of-date. I paid for a subscription last night and found the first image I downloaded to be 6 or so years old. The area of my interest had changed a lot since the "BirdsEye" image was taken so it's really useless unless you are doing historical studies.
I contacted Garmin regarding this and their response, in a nut shell was "sorry about that but that's what you get". I told them the image was really useless and I wanted to cancel the subscription and asked for a refund. No can do was their response.
Is Garmin in such financial trouble that they would loose a customer over something like this? Well, in my case they have. So long Garmin.
