Overview

The Garmin 010-10617-02 is a 6-foot (1.8 m) USB extension cable for select Garmin GXM receivers and GPS units. It gives you extra reach when the USB connection needs to land somewhere practical, like inside a helm electronics compartment instead of right at the device or receiver.

On boats, this is handy when a GXM 30 or GXM 40 receiver is mounted away from the console, or when the USB lead needs to pass through a rigging tube or cable chase and still leave enough slack for service access. It is an extension only, so it does not change connectors or convert between marine networks.

Since USB connections are not intended for exposed wet locations, plan the run so both ends live in a dry, protected space, and check that the USB connector style on your equipment matches what you are extending.

Key features

• 6-foot extension adds reach for routing through a console, electronics box, or cable chase without relocating your device.
• Supports common onboard tasks that use USB connections, including device servicing, updates, and data transfer where applicable.
• Compatible with GXM 30, GXM 40, GPSMAP 3xx series (including 376C, 378, 396), GPSMAP 4xx series (including 478, 496), GPSMAP 696, zumo 550, aera 796, StreetPilot 2730, StreetPilot 7200, and StreetPilot 7500.
• Helps reduce tugging at the port by letting you secure the cable run and leave a small service loop at the connection point.

What’s included

• USB extension cable, 6 ft (1.8 m)

Compatibility and fit

This cable is intended for the Garmin models listed above. If your installation includes a different GPSMAP generation or a different GXM receiver, confirm the unit is in the supported device list and that the USB connector style matches before routing the cable behind panels.

The 6-foot length is often enough to move the connection from an exposed mounting position to a protected electronics area, but measure your actual route length, including bends, drip loops, and any service slack you want at both ends.

Installation and routing

Route the cable away from high-heat areas and moving parts, and support it along the run so vibration does not work the connectors loose over time. In a helm console, leaving a little slack at the connection point makes future access easier without putting strain on the device port.

If the cable passes through a bulkhead or hard panel, use a proper pass-through or grommet and keep the connection in a dry area. A simple drip loop below the connector can help prevent water from tracking down the cable into the port.

Use cases on board

This extension is a good match when you need more flexibility in where a compatible Garmin GPS unit or GXM receiver sits versus where the USB connection can realistically be accessed. It is also useful for boats that are updated and serviced at the dock, where reaching the USB connection without removing electronics saves time and reduces wear on mounting hardware.
