Oh - I didn't mean to imply he answered your question - just that he's a treasure trove of more than you ever wanted to know

The Edge 500 will work with Ant + accessories - so if you already have a sensor, you're good. The Edge 200 (which looks exactly the same) will not because it doesn't have Ant + built in.
