Free software update for GPSMAP 700 series

24 January 2011

Garmin, is pleased to offer an unmissable free software update for GPSMAP 700 series allowing mariners to overlay vital radar data directly on top of charts.

Benefits of this free software include added Radar Overlay display functionality which draws returns from connected Garmin GMRTM radar over either a Navigation Chart or Fishing Chart presentation. For the best Radar overlay experience Garmin recommends using a magnetic heading sensor.

The software update also gives mariners the added option to overlay radar returns on 3D charts, the added ability to measure distances on radar displays (in the same way this can be done on 2D charts) and a depth log to the Sonar functions.

NMEA 2000® engines and tanks with pre-defined names can now be labelled, analogue display options for tank levels, rudder angle, trim tabs, bow tabs, and engine trim have all been added with an additional option to display individual engine fuel flow rate and fuel economy numbers on the numbers dashboard gauges page and in overlay numbers.

The free software update increases ease of use further by incorporating higher-resolution system fonts for improved presentation and readability.

To get the free update simply go to  and select ‘Chartplotters’ then ‘GPSMAP 750’. Click on ‘software’ from the menu on the right and follow the instructions to download the update onto an SD card.
