Just trawled through the new Mercedes Me conditions and services. There seems to be additional services for E Class 2016 and C Class from June 2017. It looks to me that the C Class gets as an option the remote park assist (the one from outside the vehicle) from June 17 model - I am sure you'll need the 3d camera, auto and keyless as per the E Class. This wasn't available as an option previously. Other new services are Dictation, In Car Office, Internet radio, Filling Station prices, Parking space availability forecast !
