You almost have to look twice to see it, but it does light up at night. The USB port is located in the middle rear of the top console tray section. Look again, you may have missed it. It is there in all 2011-12 430 and 730 radio models, like my 2012 430N RHB model. I wish the console USB port would allow accessing files via a thumbdrive, like the one on the lower right of the radio head unit. I understand the console port can only be used to plug in a device such as an iPod (which I do not have). However, the port does not self-power devices so you will be on device battery power only.
And I am still not happy that the 430 and 730 radio Gracenote software does not have current updates, does recognize any music artwork issued since approximately April 2012 and artwork uploads from the original CD only (very slow copy process) - not from iTunes, Roxio or Nero mp3 file formats. But then, not having the album artwork may not be that big a deal - it is just another example of poor software design and support of the GC media systems by Chrysler. Chrysler will no longer allow Gracenote to provide the formerly "free/anytime/online" software updates, but instead refers you back to the dealer to do the updates at a "nominal cost" (I was told $19.95) for the update and shop time (I was told 1 hour minimum charge) for the installation/reflash. Personally, I will wait at least 1+ years until I need to have my GPS maps updated at the same time. I have already found multiple errors with the 430N Garmin GPS vs my 3-month old portable Garmin unit (which is very accurate and up to date). And not being able to make any route changes, check addresses or make HDD changes while the vehicle is in drive is a PItA (ie: you cannot even do it when you are stopped in traffic, at a light, side of road, etc). Best luck.
