My Contour 200i does not appear on my iPod\ iPhone as a device to connect to!
Check that your Contour 200i Air is running the latest firmware to ensure you experience the best from your product!
It's likely that your Contour device has just performed an automatic software update over the internet. Switch on your Contour and you may see the front LED flashing red for 20-30 seconds. If so, wait for the LED to turn a static white colour and you should then be able to see the Contour device listed on your Apple device to connect to.
