Upgrading 8612052D10 to 8612052110

Did you have any issues upgrading or were all the wire connectors the same? I'm considering doing the same upgrade at some point. Does the navigation require any sort of antenna that isn't included in the base model, or is it part of the head unit?

 

There are some old discussions in this section that discuss the change. I did this replacement in my 2012 C2. It was PnP. Used an antenna for navigation. According to the old discussions, Nav is choppy if you don't. Also, you have to replace the left steering wheel button circuit card to signal the voice recognition, if you want to use it from there. The car screens (Energy Regen etc.) in the touchscreen radio require patching into other wires, which I did not do. The system has been working fine and I can initiate calls by pushing the steering wheel button and using voice.
