Just as a FYI for anyone that has the Kenwood system with the ipod connector. I had problems where my ipod(s) stopped working with the system. They would play but the system didn't recognize the Ipod and you couldn't use the Kenwood controls to pause, etc. I went to the dealer. They couldn't figure it out. They hooked me up with the vendor who installed it and it couldn't figure it out and suggested I called Kenwood. They ran me through this process up upgrading the Kenwood software to no avail.
I figured it out when I tried to connect the Ipods to my computer to download something; it didn't recognize them!! I prompt rebooted the Ipods and then took them to my smart and the Kenwood has been recognizing them every since. I called back Kenwood customer service & vendor to tell them the fix and told them I was surprised they never suggested it in the first place!!!
Rebooting typically solves 99% of all computer problems; how come I didn't remember that!
Kenwood DNX5120 (with nav system, dvd player, etc. but no rear cam). It was suggested I needed the software update and boy was that a pain! That didn't fix that problem either. Like I said. I was surprized no one else suggested rebooting the Ipods and it just didn't dawn on me until I connected them to my computer and tried to download something to them.
