My 510 has not synced via Garmin Express for a long time and now it's stopped syncing via my phone.
A quick search shows me that the newer models have the similar problems.
Garmin Australia have not been able to fix my issues so I'm left wondering why on earth I would consider upgrading to a newer version if they have the same problems.
TIME TO CHECK OUT WAHOO BECAUSE I'M OVER THE LACK OF RESPONSE OR WORTHWHILE SUPPORT
