a97 display comparability with E66056 transducer

Question 1) I am planning to purchase a a97 pt n# E70233-US and have a transducer PT# E66056 already installed in the boat, is this transducer compatible with the a97 display.

2) Purchasing a EV-100 power autopilot PT # T70154: are there any communication cables or linkages that are required to connect this to the a97 display.

3) PT# T70154: Is this a complete kit or do I need to purchase an additional linear actuator to feed back engine position (engines are two F115 Yamaha)

4) Will be installing the a97 display on center council under a canvas T-Top do I need to install a separate GPS antenna?

Thanks for your assistance. or sugestions
