i70 not showing speed

[Chuck - Raymarine - Moderator]

Sfkjeld,

The i70 Multifunction Instrument Display does not feature an internal GPS (or any other sensor for that matter). The i70 Multifunction Instrument Displays are design to be repeaters of supported data which is present on the SeaTalkng / NMEA 2000 backbone to which it has been interfaced. Per the earlier response, if seeking to have the i70 MFID report the Speed data item then the powered and properly terminated SeaTalkng backbone would need to be interfaced to a speed through water sensing device (ex. iTC-5 w/compatible instrument speed/temp transducer, i50 Speed System, etc.). If seeking to have the i70 MFID report the Speed Over Ground (SOG) data item then the SeaTalkng / NMEA 2000 backbone would need to be interfaced to a GPS sensing device (ex. Raystar 130 GPS Sensor, etc.).
