I apologize if this has been discussed. A quick search did not yield any results and I wanted to find out if there are any interference issues between MS 900 and the Edge 500 like the other cyclocomputers. Currently I have a Blackburn computer that thinks I'm riding 144 mph when I turn my MS 900 on. I'm thinking about getting the Edge 500 with cadence sensor and the heart rate strap. Anyone out there using the same combination with/without any interference issues?
