I received an email to update my Edge 530 software from 5.10 to 5.50. I went and downloaded the software and placed it in the "garmin" subdirectory of my edge when it was plugged into my PC. I then proceeded to reboot my Edge 530 and when it came back up the Garmin Expressed searched for new software but did not find it. The file was call gupdate.gcd again under the garmin drive on my Edge. Am I doing something wrong if so please advise. Thank you.
