Garmin 540s Review

This Garmin 540s was destined for installation on a 19-foot center console boat used primarily in the waters of the Upper Florida Keys. The boat’s owner was looking for a compact multi-talented unit to replace an antiquated non-operational chartplotter.

Shop for the latest Garmin 540-series chartplotter combos here.

In this configuration the 540s had an internal sounder, internal GPS receiver, and was preloaded with Garmin BlueChart g2 U.S. Coastal cartography covering both coasts, Bahamas, Puerto Rico, Hawaii, Guam, and the Great Lakes.

Garmin 540s

The 500-series plotters measure 6-inches high by 6.2-inches wide and just under 3-inches deep. They are available in a number of configurations.

All 500-series machines feature a display screen in portrait layout that measures 5-inches on the diagonal and carries either 320 by 240 or 640 by 480 pixel resolution.

Units with a last numeral in the model number of 0 have the lower resolution while those ending with a 5 have the higher.

The small ‘s’ suffix appended to the model number indicates the unit has an internal sounder, high resolution units have a 1000-watt sounder while lower resolution units get a 500-watt sonar.

The center number in the model designation identifies the cartography coverage area, 5 is UK/Australia, 4 is US coastal, 3 is US inland lakes, 2 is base map only.

All 500-series units are capable of using Garmin BlueChart g2 Vision cards.

The flush-mount has a gasket to prevent water intrusion around the unit. Once the flush mount bracket is installed the display unit simply snaps in place.

Power and NMEA 0183 data pass through a single cable that fastened to the case back with a twist lock connector. The additional leg on this cable connected the supplied transom-mount transducer to the display unit.

An optional external GPS sensor can be added if needed or desired and connects to
