The old style 12 pin connector was used when Apple still used the Firewire system. In 2010 Apple went to supporting the USB profile and is when Uconnect changed their system to support USB connections also. There isn't a connector to go from the Firewire to USB, it's 2 totally different communication types.
Chrysler radios with the USB on the faceplate don't have the chip needed to play Apples media files, the Uconnect module does have it though. The radio mounted USB connector is used for charging phones, playing audio from a thumb drive and downloading pictures & audio files to the HD. No, the USB does not discriminate between devices but the device that the USB connection is made to has to have certain chips & SW in order to play various files. Such as the USB connector in your 2012 vehicle can play older phones (other than Apple devices) stored media files but as of 2012 the phones have gone from supporting the ability to be used as a "Mass storage device" which is the same as a thumb drive to supporting MDP files which are not supported by the Uconnect system. So you can't play newer phones media files in a cabled connection. Only by streaming thru BT.
The pre 2011 vehicles Uconnect system does not support the USB communication signal so the only way to get the similar connection as in your 2012 vehicle is to change out the Uconnect module to a newer part (such as 05091959AA) and add the optional USB / Ipod cable (82212160). It would be a simple unplugging, removing the old module, mounting the new module, plug it in and run the USB cable to the glovebox or center console (which ever you decide on).
Hope this info helps you out.
Sorry, are you saying ithe input for your NAV is not USB compatible? I'm really surprised they'd have designed a product that could only be serviced by one platform. Who approved that?
I use the cable that I charge my iPhone 5 with in my 2012. (Just remove the cable from the plug part. It reveals a standard USB connection that I plug directly into the NAV console (switch on bottom right flips up to reveal the port, and there's a second port in the front wall of the well between the front seats). They are all standard USB ports and do not descriminate between android, apple or windows products. Just be sure your NAV is set to the correct input and all should hum.
But if it isn't USB, then a trip to Radio Shack or any descent computer store should hook you up quickly.
