i-pilot questions.......

I have the itch for an i-pilot. Will order one soon with Cabela's deal going on right now. Questions:

1. What is the difference between the PD V2 and the Terrova w/US2?
2. Is the optional foot control nessary?
3. Will it plug into the motorguide receptacle I have now?

Thanks for your help.

The Terrova is a larger/stronger motor. You can use the foot pedal with the Terrova and i-pilot, the Pd v2 doesn't have a footpedal with i-pilot and an optional foot pedal won't work with i-pilot installed. You can change either the plug or the receptacle, your choice.
