The Striker power/data cable consists of four wires:

Red and Black - The red wire will connect to your positive battery terminal, and the black wire will connect to your negative battery terminal.

Blue and Brown¹ (Optional) - The Blue wire is the Tx (Transmit), and brown is the Rx (Receive) wire. These wires are used only for Garmin Data Sharing between the Striker and the ECHOMAP² series devices. If these wires are left disconnected, Garmin suggests clipping the stripped tinned ends back to the insulation.

To initiate data transfer on the Striker:

1. Home

2. Select User Data

3. Select Manage Data

4. Turn User Data Sharing On

To initiate data transfer on the ECHOMAP:

1. Select Nav Info

2. Select Manage Data

3. Turn on User Data Sharing ON

Once User Data Sharing is on for both devices, the User Data automatically shares with the connected device.

In the event the power/data cables won't reach between the two devices, Garmin offers a User Data Sharing Cable that can act as an extension. For information on connecting the User Data Sharing Cable, please consult the installation instructions included with the Data Sharing Cable packaging.

¹The Blue and Brown wires are for Garmin proprietary user data sharing only. They will not support NMEA 0183.

²Not all ECHOMAPs have user data sharing through the blue/brown wires check the owner's manual (ECHOMAP Chirp 7x/9x and ECHOMAP Plus 7x/9x do not share via the NMEA 0183 blue and brown wires)
