Hey I have a Jeep Grand Cherokee 53 Plate (2003), I dont have a sat nav CD and I found one online here , but im not sure if it will work, the sat nav unit shown is the same but im worried that the 2011 CD wont work on my 2003 Car, Or is it the case that 2011 is just the year in which the maps are up to date as of the CD. Here is pic of the unit in my car if it helps: here (pics)

I would be very grateful if someone can tell me if the disc will work or not.

Thanks
