Wire Functions of the Garmin STRIKER Power Cable and How to Initiate User Data Transfer
The STRIKER power / data cable consists of four wires:
Red and Black - The Red wire connects to the positive battery terminal. The Black wire connects to the negative battery terminal or ground.
Blue and Brown (optional) - The Blue wire is the Tx (Transmit), and the Brown is the Rx (Receive) wire. These wires are used to share user data between the STRIKER and the ECHOMAP¹ series devices. On most of these devices, the Blue and Brown wires will not support connected NMEA 0183 devices. If these wires are left disconnected, Garmin suggests clipping the stripped tinned ends back to the insulation.
To initiate data transfer on a STRIKER or echoMAP CHIRP device:
From the Home screen, select User Data
Select Manage Data
Turn User Data Sharing On
To initiate data transfer on an echoMAP device:
From the Home screen, select User Data
Turn User Data Sharing On
To initiate data transfer on an echoMAP 50, ECHOMAP Plus, UHD, or Ultra device:
From the Home screen, select Nav Info or Navigation Info
Select Manage Data
Turn User Data Sharing On
The devices will automatically share user data when connected to the data sharing wires when User Data Sharing is enabled.
If the data cables are too short to reach between the two devices, Garmin offers a User Data Sharing Cable that can act as an extension. See the Data Sharing Cable's installation instructions for steps to connect the wires to the device.
1 The 7x and 9x models of the ECHOMAP CHIRP, Plus, and UHD series do not share data through physical wires. The Blue and Brown wires on these devices only connect to NMEA 0183 instruments and devices. See the device's owner's manual for steps to transfer user data.
