OK I got my GPS working, Thanks.
Now i need to get my transducer working. I was told to look at the cable going into the back which right in, but there is only an orange piece of paper with no info on it. I am replacing a Furuno GP-1650WDF GP 1650 WF with c-map it was bought and installed 2005 to replace an older Furuno GPS. We used the existing transducer and it worked well with the new one. The transducer has a speed wheel on it. Any ideas on what it might Be ?
