I just upgraded my 2007 RRS Factory Nav disc to 2011 - 2012 Nav disc. Cost was $199.00USD plus Shipping for the disc itself. Get it from here:

Installation is simple:
0)
Start your vehicle and leave it running through the entire process
1) Save your driver's seat position to memory if you already haven't (see your vehicle manual on how to do this).
2) Move the front of the seat all the way up (it will only go up about an inch or two)
3) Move the entire drivers seat all the way forward
4) Look underneath the front of the seat and you will see a bunch of wires and a DVD player
5) Change the lock switch on the right hand side of the DVD drive (when facing it) to the unlocked position
6) Push the eject button on the left hand side of the DVD drive (when facing it) to eject the old DVD disc
7) Remove the old DVD Disc just as you would any other slot load DVD disc
8 ) Insert the new DVD disc, label side up, just as you would any other slot load DVD disc. The player will grab the disc when it is part way inserted and draw the disc in, DO NOT FORCE THE DISC IN. If the disc doesn't go in smoothly you either A) Haven't removed the old disc or B) You have a disc player issue or C) Your vehicle isn't running.
9) Once the new disc is in the player change the lock switch on the right hand side of the DVD drive (when facing it) back to the locked position
10) Return your drivers seat to its original position by pressing the appropriate memory button (1, 2, or 3) that you saved its position to in step 1.
11) On your NAV screen you will see a message something like "Please wait while the data is loading" and a green line. This will take a couple of minutes to complete. DO NOT TURN OFF YOUR VEHICLE OR TOUCH THE NAV BUTTONS while this screen is showing.
12) Once the message from step 11 disappears and the map screen shows the "Don't enter data while driving" message press agree and your new maps should appear
13) All Done
See the attached pictures for what you should see when looking under the front of the drivers seat and what the 2011 - 2012 maps look like on a 2007 RRS.
Works like a charm.
