Adding a C95MFD to Garmin GNX20 Instruments

I recently purchased a 35ft C & C that has pretty new (less than one year old) Garmin GNX Instruments and transducers. I would like to add a C95 MDF and a P70 Auto Pilot. I'm pretty new to this so my question is..Will all of these "speak" to each other? If so, do I need any converters or adapters of any kind?

Thanks in advance, Don
