 Yes it is possible to retrofit CCC in E70 in case if it come with no nav from factory.
You will need to buy CCC navigation from ebay. Technically you need only the screen and main module (CCC module). You also will need two cables - cable to connect display and CCC module (I will tell you how you can use your original existed cable if you do not want to buy new one). Another cable is the FAN cable, but I can also tell you how to build one your self if you want.
