Garmin 3210 - FMS on f-250's

I'm trying to hook up my Garmin 3210 to my Fuel Management System on twin F-250's. Is this possible?? There is nothing about it in either owners manual. Thanks for any help!

You would need 6Y5-85721-F0-00 GPS signal lead and connect white wire from signal lead to NMEA 0183 output lead of GPS and change # 5 dipswitch in back of FMS to the up position.

Thanks for the reply!! If I wire it this way, do I lose my ability to see my fuel #'s on the Fuel Management System Gauges? Thanks again for any help!

No it will just use GPS speed instead of Speedo speed signal for calculations.

Thanks again, boats.net!
