| Okay, I just bought a boat and right away upgraded the trolling motor to a terrova.  After spending the money on the trolling motor, I didn't want to chunk a bunch more money down on a fishfinder just yet, and, since everything on Minnkota's website said it would be compatable with the fishfinder 160, I decided to get the universal sonar option on the trolling motor and use the adapter cable for Garmin fishfinder.   
  
Now that I have it ready to rig up, I found the adaptor cable that I bought doesn't seem to fit the fishfinder.  The head is a lot smaller than the socket on the back of the fish finder.  But it clearly says on the website, and on the package of the adapter cable I bought, that it is compatable with the Fishfinder 160.  Anyone else dealt with anything like this?  
  
I don't really have the money to go buy another fish finder right now.
