Thanks. I understand the differences in connectivity. if i get the ant device, i will need the ant + iPhone key to use my ipad to control the trainer. will my cadence and hr be picked up with the ant+ iPhone key, or will i need to have my garmin on to get this information if i go with the Bluetooth, then i don't need the ant adaptor, as my ipad will connect via Bluetooth. but then for cadence and hr, i will need Bluetooth devices to get this information to my ipad.
