I just purchased a Lowrance

Question

I just purchased a Lowrance LCX-20C from my local West Marine store. It was used by the store in their boat. A cable described in the manual as "Splitter plug with a 25' Y-adapter extension cable" is missing. Store is not cooperating and has not yet ordered the cable. Please let me know:1. How much a new cable will cost and 2. how fast can you get it to me?Thanks for your helpAl [e-mail]
