Garmin not showing Birdeye.

Have any of you had any trouble with your 320 not showing the Birdseye images that you've downloaded to it when you turn it on? I've had mine since the first of the year and it's worked flawlessly unitl now, but on my last 2 trips to GA it has failed to show the Birdseye images that are on it upon start up. I called Garmin the first time from the woods and got a guy that was really helpful.....talked me through a master reset I think he called it. When it loaded up the maps on power up, the Birdseyes came right up. Happened again last weekend and I did the reset thing and it loaded them again, but you lose all dogs on your list so you have to enter them again which is a pain of course. Just wondered if I was the only one to experience this trouble. Thanks.
