Replacing a GSD 26 Sonar Module
If you are upgrading from a GSD 26 sonar module, observe these considerations.
• The GSD 28 device is horizontally smaller than the GSD 26 device. If possible, you should reuse two of the
mounting holes on the right or left side of the mounting surface and drill two new holes for the opposite side.
Both models use the same size mounting screws.
• You can use the included Garmin BlueNet to Garmin Marine Network adapter and the existing network cable
to connect the GSD 28 device to a legacy Garmin Marine Network device on your network

Mounting the Sonar Module

Mounting Location Considerations

• You must mount the sonar module in a location where it cannot be submerged.
• You must mount the sonar module in a location with adequate ventilation where it will not be exposed to
extreme temperatures.
• You should mount the sonar module so that the LEDs are visible and the power and network cables can be
easily connected.
• You should mount the sonar module in a location within reach of your transducer cable. If required,
transducer extension cables are available through your Garmin dealer.
