Is the chartplotter connected to the autopilot via NMEA wires? I would start by checking that out....it is the way that the chartplotter gets info to the AP.

well, used boats are always an adventure. Like STxFisherman said, first amke sure the Furuno's NMEA data out is connected to the AP16's NMEA data in. next check the manuals for both and make sure as many of the sentences that the ap16 will look for are turned on to transmit on the nn2 display. Is the AP16 giving the no data message whn you try to put it in the track mode?

AP16 in "Auto" steers the course when the "Auto" button was pushed.

You need to push the "Nav" button to have the AP16 navigate to the waypoint that the GPS is set for. If the AP16 gives you an error message when you go to "Auto", then the AP16 is not getting NMEA info from the GPS (assuming the GPS has been set to navigate to a waypoint).

My AP16 gets NMEA input from the Lowrance LCX-112C and followed a 75nm course from the Norfolk Canyon to Little Creek, never getting more than 200feet off the track line - and that was in a quartering sea.. [img]../jscripts/tiny_mce/plugins/emotions/images/smiley-cool.gif[/img]

Recommend you check to be sure NMEA output is enabled on the GPS. Also check that the buad rate is set to 4800.

If those are already as they should be, then I would suspect that the "hooked together in the back" may not be done properly.

Sorry, no experience with Furuno. Perhaps a look in the manual will provide some info...

and I meant "baud" rate above.

Baud rate is the speed of the connection. 4800 baud is the most common, and what your equipment probably is operating at. Other common rates are 9600 and if you have AIS - 38,400.

Bottom line is that your transmitter (the display) needs to be transmitting NMEA data at the same rate as the receiver (the autopilot), or they won't talk.

you have to have a waypoint set in the furuno, then go into the menu of the Simrad and select Auto Source Update. this will look for all available data on the incoming Nmea ports. after that, you should be able to NAV from a waypoint. If that still doesnt work, then its probably a wiring/setup issue.

Baud rate is the speed of the NMEA out line. All you need to know is that the transmitting unit and the receiving unit must be set to the SAME baud rate. So, as suggested, 4800 bps is the number in this case.
In your Furuno manual, locate where the System Setup is presented (I think they're in the appendix). It should state how to get to the screen and set the baud rate, output sentences etc, if applicable. It doesn't necessarily have to be an autopilot that receives the NMEA info from your Furuno, that is why your manual does not specificaly mention it
If everything is set as required then, check the NMEA cable between the Furuno and AP. It may be loose or bad.

Good luck.
