Believe me or not, I couldn't get Garmin Connect Mobile to show up in iTunes last week unless I switched to iPhone-only, and then it said my device was incompatible when I tried to download it. I think that some revision happened; at least that's my story, and I'm stickin' to it. I also know that I read in either my paper manual or somewhere online that the Edge 25 did not support Bluetooth with iPad, only smart phones, though it may have been in reference to some other feature than uploading.
In any case, yes now I've synced, and as soon as I recover my health, I will take a ride and try uploading through my iPad rather than my PC. Seems that my touring issue will be solved!
