Hi My car is A6 C7 2,0tdi avant 2011/12 Can someone help me with this: I just call audi dealer here in Finland and i told that i want to upgrade my car mmi radio plus to mmi navi low. They told me that this is impossible because they can not parametrize used mmi unit with navi option to my car.. So what i do, i think Kufatec can but their option(2229e) is too much. Will used mmi navi low unit work in my car if i find unit with same option?(cp can be removed by dealer they said) What about if used mmi low unit has more option than mine...? i just got BT,mmi radio plus, parktronic front/rear. So lot of to think, what should i do?
