My Edge 1030 worked perfectly until Garmin updated the software to 6.2 and subsequently 6.4, now my HR and cadence sensors fail to connect on start-up and drop out if I pause for more than a few seconds during a ride. That however is not the main issue, which is this: This is a Garmin forum but nowhere can I see a reply to any of the posts from Garmin offering help or support with this issue, which they have created. I'm not sure which is more annoying the dropouts or the complete disregard for their customers who spend hundreds of pounds on their products. They haven't even bothered to reply to the support email I sent 7 days ago. Garmin get your house in order!!
