Overview
The Garmin 010-12390-10 is a 15-foot USB cable that links a GPSMAP 8400 or 8600 series chartplotter to a computer for touchscreen control. Use it alongside a compatible HDMI cable (sold separately) when you want the computer’s video on the chartplotter while sending touch input back to the computer.
The connection is built for helm use where spray and vibration are normal, and it supports touchscreen interaction on the chartplotter, including on-screen keyboard control when the computer is connected. It works with Apple computers and with Windows 7, 8, or 10 systems.
Key features
- 15-foot (4.6 m) cable length for routing from a helm display to a nav station or electronics cabinet
- Connects GPSMAP 8400/8600 series chartplotters to a computer through USB for touch control
- Pairs with a compatible HDMI cable (sold separately) for the video side of the connection
- Connection that resists water and stays secure in typical marine mounting locations
- Supports touchscreen operation on the chartplotter, including interaction with an on-screen keyboard
- Computer compatibility: Apple and Windows 7, 8, or 10
Installation and setup
Plan the cable run the same way you would any helm electronics wiring: avoid sharp bends, protect it from chafe at bulkhead pass-throughs, and leave enough service loop behind the display so the unit can be pulled forward for service. If your computer is mounted under a console or inside a cabin cabinet, the 15-foot length helps reach without putting strain on the connectors.
Keep the USB and HDMI runs tidy and secured so vibration does not work them loose over time. A small drip loop near the connection point is a simple way to reduce the chance of water tracking down the cable toward electronics.
Compatibility and fit
This cable is for Garmin GPSMAP 8400 and 8600 series chartplotters. On the computer side, you will also need an available USB port and a compatible HDMI connection for video (HDMI cable not included). If your setup uses a different GPSMAP series or a different video interface, confirm compatibility before routing cables through the boat.
Use cases on board
This is a practical add-on for boats that keep a laptop or small PC on board and want to interact with it from the helm display. It can also make sense on larger center consoles, sportfishing boats, and pilothouse setups where the computer is mounted out of reach but you still want touch control at the display.
Maintenance and care
After washdowns, check that the connection area is dry and that the cable is still secured at clamps and tie points. If the cable passes through a high-traffic locker or rigging tube, inspect the jacket occasionally for wear and re-protect any spots that may rub under vibration.
