Garmin GPSMap 76 USB Interface

I’ve owned the Garmin GPSMap 76 for a couple of years now, and it has proved to be a good, capable unit.

This was purchased as a “Plan B” in case we lose the 2010c Garmin that is installed at the helm.

I purchased the USB cord from a supplier on eBay, Kawa, and I received it promptly after paying.

The cord doubles as a power cord, and when connected can provide data to Garmin Map Laptop program or to Maptech Offshore Navigator.

In order to get it to work with Maptech Offshore Navigator, make sure you configure the Garmin GPSMap 76 first.

Hit the menu button twice, highlight “Setup”, hit enter, then highlight the “Interface” tab. Here you can change the setting to NMEA, thus allowing the unit to talk to any NMEA capable software.

It worked great; I had it up and running on my laptop within minutes. Before you plug it into your USB port, be sure to install the drivers FIRST from the mini-CDROM that comes with the cable.
