Annoying problem on today's ride - the garmin wouldn't consistently read the speed I was going, resulting in some hilarious moments where it couldn't decide between GPS or the wheel sensor and then told me I was going 120 MPH. Wheee
Anyone come across a problem like this before? I'm guessing it's a dodgy connection with the wheel sensor... it was reading cadence just fine, and I swapped the battery for a new one and was still getting the problem. The arm was as close to the magnet as I could safely get it - closer than I'd usually have it in fact.
