Hello - Navigation experts, i'm looking at a 2004 C230K , it has a navigation , however it does not have the CDs and the navigation is not 'setup' .. How much would it cost to activate the nav (install the CDs ...etc), any feebacks on the COMND nav for 2004 seems like it is CD based

 

In other words, where can i shop for these CDs OR DVD, and can i install myself?
