Last night I went for a ride to the supermarket, 8 miles each way, with Live Track enabled. I was nearly home, when the 530 displayed a text from my wife "Are you stuck?". I replied "No" and carried on. When I got home, she showed me the Live Track on her iPhone - it was stuck at the supermarket with a spinning circle. I loaded the Live Track link on my PC browser and it was the same, even though I had already ended the ride. I definitely had had a good Bluetooth connection to my phone and a mobile signal, because I received my wife's text, and she received my reply.
On my commute this morning, it failed in the same way, but only after 0.48miles. Again it is stuck with a spinning circle, even though I ended the ride some hours ago.
I've used Live Track on every ride for the past two years and this has never happened before. Is something broken at Garminland?
