I have an iPhone 4s and a Garmin Edge 510. The 510 will not sync rides on a daily basis, I've turn off auto upload as it never worked for me. The Edge does get weather updates from the iPhone though.
Recently I was in Spain for 4 weeks and the upload function worked every time without failure! I even turned on auto upload and it worked for 3 weeks without a failure.
When I came back to Ireland it reverted back to failing each time. Please help me. I dont have a PC so cannot connect my Edge 510 to upload my daily rides. This is so bad, its the only reason I bought a 510, because it allows bluetooth connectivity.
Has anyone else experienced this, espically anyone from Ireland, where it works elsewhere? I've since tried my Edge 510 in England and again uploads worked.
