Looks as if Apple is trying to force you to buy their plugs etc. Problem is that this does not help you with the supplied Jag connector. I would simply change to a more accommodating case and dump the Apple bumpers (albeit that they tend to make the 'phone slightly larger - mostly in depth).

It's the voltage that has changed.
Devices that would charge the older-style iPod/iPhone (pre 3G iphone) basically used a Firewire 1394-style pinout (12 volt). Apple abandoned Firewire starting with the iPhone 3G and went to a standard USB style charging setup (5 volt). It's lower voltage than Firewire, so it doesn't charge as quickly, but Firewire was never a popular format to begin with.
So newer devices that use the 5 volt charge input cannot accept the 12 volt charge input that older speaker docks and in-car entertainment systems attempt to provide. They can still pull the data since those pins are the same, but the voltage is too high for the iPod to accept. As a safety feature, it "rejects" the 12 volt charge instead of accepting it and burning up the electronics/battery.
Similarly, the USB cable that jagular used is compatible with either since it's input is 5 volt by default. A device that operates at 12 volts can accept a 5 volt charge - it'll just be slower to charge.
I'm no Apple Genius or engineer, but when manufacturers struggle to adapt to proprietary technologies from VERY popular companies like Apple, parts departments have to answer a lot of questions.

I believe the standard Jag connector has only 12v and connects to the so called FW 12 v power pin on the connector which will not charge devices designed for 5v.
Whether or not an Apple device that uses the 12v feed will charge from the 5v pin seems to depend on the device and year. Some do, some do not. However you are more likely to find 5v devices that will not work with connectors that are only provided with 12v.
I hope this clarifies this for you (I have designed a number of systems to connect to Apple devices in the past!!).

This is excellent information. Jaguar is clearly responsible for keeping their equipment up to date if they want to claim compatibility with another manufacturer's device. Jaguar should supply the correct new cable free of charge unless the spec change occurs after the date you buy your new car.

In my mind, Jaguar stepped on their crank by trying to be accommodating and supplying a cable in the first place. They should have just said, "Here's the interface, hook your device to it."
Just my opinion, thanks for listening.

Ipod cable connector provided
Thanks members. I just acquired my 2011 XF Premium and researched the reasons for no Jaguar proprietary cable being provided. After calling Jaguar USA my dealership in Bellevue WA was contacted the same day and authorized to provide the Jaguar cable connector at no expense. Dealership sells them for approx. $100 US. Thanks again for the information.
