Posted this on the I-pilot Forum , So I'll try it on this one ? maybe a real dumb ? but to save me some Money ?anyway here goes,

I have a 55lb PowerDrive V2 on my boat now, thinking of getting the i-pilot for it $400,
do away with the foot control, then maybe if the money gets better next year get an 80lb Terrova, Will the setup on the PDV2 change over to the Terrova ?? or will i have to get the Terrova with the i-pilot ? thought maybe there was away to save some money if it would somehow work.looking at $400 now & $700 next year plus battery 24volt,If, or $1400 plus battery,
Thanks
