The treadmills at my gym have 30-pin ipodiPod connectors so you can control it and watch video on the treadmill screen. However, the new ipodsiPods don't have the old 30-pin connection, but have the smaller lightning connector.
Converter cables are pretty cheap, but I'm concerned that the video playback won't work through the converted cable. Some googling doesn't see to give a clear answer, and I'm not sure if anybody has actually tried it, but I'd like to clear it up before I order the converter cable and try it myself.
Has anybody connected an ipod nanoiPod Nano to a treadmill and been able to successfully play back video?
