O.K. I'm sorry to be such a pain but I'm wondering if I need the 787 since I'll be sharing the GPS info with the Humminbird 997. Does anyone know if there is a unit available without a transducer or GPS antenna installed? I'm guessing the interlink box will allow me to share the GPS puck I already have. Just trying to buy the right thing for the least amount of money since I've invested so much in the main unit.

Thanks,
Buzz
