A Garmin Nuvi is a GPS navigational system. It comes with all of the electrical attachments for mounting, including a 12-volt receptacle plug for your cigarette lighter. For a permanent mounting, the unit must be hard-wired directly into a vehicle's electrical system. To do that, you'll need a Garmin Nuvi hardware cable specifically made for hardwire applications.

- Garmin Nuvi hardwire cable
Park your vehicle on a level surface. Turn off the ignition and open the bonnet.
Run the Garmin Nuvi hardware cable wires through the firewall of your vehicle. Follow the path of the wiring harness and push the wires through. Pull them out of the firewall location from beneath the hood and run them to the battery.
Loosen the nuts on both the positive and negative battery cables with a wrench. Wrap the black wire from the Garmin Nuvi hardware cable around the negative post that the nut screws onto. Wrap the red wire around the positive nut post. Do this exactly as you would if joining any type of electrical wire to any regular electrical post. Tighten the nuts to secure the wires firmly to the electrical terminals.
Plug the hard-wired cable directly into your Garmin Nuvi GPS. Turn it on to test it. Close the bonnet of your vehicle. Your Garmin Nuvi has now been effectively hard-wired.
Tips and warnings
- To secure the wires from the Garmin Nuvi GPS unit that run to the battery, connect them to other wires going in that direction using zip ties. This will make the hardwire connection neater and it will keep the Garmin Nuvi wires off to the side and out of the way of moving engine components.
