Ok so the message that Tischer posted on their website about it not working on early versions of CIC was false in my case. My car is one of the first 09s (build date of 09/2008)
I downloaded the 2013 maps, got my FSC code and uploaded via glovebox USB no problems. I now have 2013 maps. A lot of 3D was added in my city. Here are some pics:
