2. Make sure your Nav is OFF and fully CHARGED
3. Plug your console controller into Port 3 on your XIM4
4. Plug your Nav wired (using a mini-USB cable) into Port 2 on your XIM4
5. Connect your XIM4 to your console that is already on
6. Wait for your XIM4 to initialize
7. Verify your Nav is working by using it’s analog stick and pressing it’s buttons
8. Unplug your Nav
After these steps, your Nav will be paired with your XIM4. These steps only need to be performed once. Next time
you power up your XIM4, simply press the PS button on your Nav and it will connect to your XIM4.
