How often are Birdseye Satellite Imagery Maps updated?

Just curious if anyone knows how often Birdseye Maps are updated?  I just went to use it for the first time and when I mapped an area of my neighborhood I was surprised to see two trees in my backyard that came down in a winter storm 7 years ago and my old white Dodge Ram in my driveway that I traded in 9 years ago.  I planned to use these maps for hunting and hiking, but I'm wondering what value they'll be worth if everything's nearly a decade old.

  • The Garmin support response wasn't very helpful.  They said that there are unpopulated areas where there isn't much change that don't get updated as often.  I live in a Seattle suburb that has more than doubled in population and with new infrastructure in the last 10 years, so I'm calling BS.  Anyone else noticing this with their Birdseye Satellite Imagery maps?  Do you find the maps fairly current?
