I have attempted via garmin express and garmin connect mobile to upload courses to my Garmin 510 and every time I try i get a transfer error. The firmware I have installed is v3.5 and I cannot update this at all because somehow the install will not fit on the internal memory. I find this incredible since I have restored the device to factory settings.
Does anybody know why the 4.2 firmware will not install on my device and why despite this I can't upload a course to my device?
The device was working fine a month ago and now one of the only features i care to use has stopped working.
I have retired the device from garmin connect and re-established it to my account and this didn't work? Im all out of ideas
cheers
