Updated my maps to the 2017 maps from
Bimmercoders
Very good price, plus they had a code discount (I believe it was "mike", but not sure). So basically for 26 $ I have new maps. Got the code within an hour, had a couple of small snags, but they were on the ball right away. very pleased how everything went. Maps are OEM and they show in the Navi about.
I know one can hack some codes to get updates, but In my case it's not worth it to risk brick my CIC for 26-30 bucks...
