Matt,

Q1. Would you consider a separate speed transducer necessary in place of using GPS for speed over ground instead.
A1. I don't believe that a speed through water sensor would be applicable to this installation. Speed though water has value in the following craft:
- systems feature an autopilot which is designed to use speed through water data to optimize the autopilot's performance in handling leeway forces
- systems feature an autopilot which operate at trolling speeds
- sailing vessels seeking true wind data

Q2. If opting for the above and relying on Axiom GPS, does the 9" / 12" come with a GPS antenna? If not which extra parts will I need to order.
A2. Axiom MFDs feature an internal GPS receiver utilizing an GPS antenna which is also internal to the MFD's housing. Please click here to view a FAQ addressing when an external GPS sensor may be required. In such cases, a Raystar 150 GPS Sensor would be recommended.
