Hey there not sure if this has been posted in here or not but I could not find an answer here. I did find a post on a challenger forum so I'm copy and pasting for ya'll. Hope this helps! It did on my RBZ 430 head unit in my 2011 Dodge Ram 1500 Sport. My Iphone 4S and 3GS both will work from the in glove box USB connection and I can control my iphone(s) with the steering wheel controls. I ran my truck the whole time I was doing the update just to make sure it had power to finish the update. Hope this helps. Ensure you download the right file for your vehicle. I am also certain that this update is only for 2010+ dodges (dont quote me on this).

Alright guys, here are the instructions.

1) First check to see which version of software your Uconnect came with. On my Patriot the module is behind the glove box and is easy to get to. I am not sure how easy this is to access on other vehicles.

Look at the SW number on the module. If you have SW 43.01.10 or 43.1.30, this update should work for you. This is where you find the SW number:

2) Download the file:
For US mid-large vehicles (Wrangler, Durango, Grand Cherokee, Town & Country van, RAM), download this file (http://www.mediafire.com/?ym7cudem8c9lb96)
For US small vehicles (Compass, Challenger, Patriot, Caliber, 200) download this file (http://www.mediafire.com/?ygm74est6j6pj19)

For Euro large vehicles, download this file (http://www.mediafire.com/?qbjepsjq2g5jcjj)
For Euro small vehicles, download this file (http://www.mediafire.com/?mp2zbywzdmd2o87)

3) Put this file onto an empty usb drive

4) Plug the usb drive into the vehicles remote USB port (NOT on the radio). It should be either in the center console or glove box

5) Press and hold the Uconnect Phone button for approx. 15 seconds, until you hear Software Update started

6) Wait until the update is completely finished (about 10-15 minutes or so) During this update, the radio will beep over and over (you can turn this down with the volume ****). If after about 5 minutes you hear "This file archive not compatible with this vehicle," than either you used the wrong download, OR your radio does not currently have an update available

This update is only for 2011 vehicles built prior to 6-1-2011. It will also work on some 2010.5 vehicles. The Uconnect module PN needs to be looked at, if the PN ends in "AF" then it will work. The Uconnect module needs to be an "AF", "AG" or "AH" PN.
