Haven't had any experience with the new I-drive, but from the current, I can say I-drive has nothing to do with the video system. All it does is switch the audio from the rear DVD player so it can be played through the vehicle speakers. Having said that, all we're interested in is power to the monitors and the input of a video signal coming from the rear DVD drive or whatever source you may have. The X5 setup looks horrible (the ones that stick out from the back seats) and the Invision system still takes a little getting use to as I prefer the integrated look.
