In response to a PM that I received today from a member:
I know that I have this information in several threads, but I can't remember which ones. So I'm going to start a thread with the update title.
This is the update that has been out since June of 2011. It's for 2011 vehicles that were built prior to 6-1-2011 and have the Mitsubishi radios (RES, REQ, RBZ & RHB) ONLY. It is not for the Harman radios (RER, RHR).
This update will fix the "error occurred" that is displayed when connecting an iPod or Iphone to the docking cable. It will also fix the choppy audio when streaming audio thru BT.
Here are the instructions: Make sure that you DO NOT have any power interruptions during the update, for best results have the motor running so there are no interruptions).
You will need at least a 2 GB thumb drive. If you have files on the thumb drive, please delete them and format the drive (to FAT32) just to make sure that it is completely clean.
Download it to the thumb drive that has no other files on it and the file name is - uconnect.upd -Turn the radio on, Place the thumb drive in the center console USB connector (on vehicles with the dealer installed unit, it should be in the glove box), press and hold the Uconnect button for about 12 - 15 seconds, you should here "update started". This process should take about 15 - 20 minutes, there will be some beeps during the process. Please listen during the update for any error message that may be said by Uconnect. When the update is completed, the radio screen will go back to a radio display. Turn the ignition off, open & close the drivers door. Wait about 1 minute, then turn the key on and test the system.
**** In some cases the extension .upd won't be recognized due to an earlier chip, please make the extension .upn *******
and here is the file location:
