Thought I'd ask a specific question as I only want to do the install once. Has anyone installed a 5120 with the iP300v from Kenwood and hooked up a 4th gen nano? Have there been any problems playing audio AND video? I'd like to get movies from my nano to play on the HU. Kenwood is releasing the ip301V to combat the earlier issues that the 300 cable had but doesn't list the 4th generation as a compatible model. Thanks in advance.
