I have connected my old iPod mini to the MMI using the provided AMI cable (with dock connector) that came with the car. However, there is a bit of lag when moving the next track or previous track (about 2 seconds).
My previous A3 (without MMI but iPod connector in glove compartment) using the very same iPod was a lot more responsive.
Is it due to the MMI itself being slow or just the old iPod?
Is reading from an SD card more responsive?
