pPC6: Coiled cable Power Cable for 10-32 Volt Garmin GPS (4pin round plug).

This cable supplies power to your GPS in the car. Save your batteries for the hike. Cable is only about 1.5 feet long but extends to 6 feet when stretched. We also have a ferrite bead near the GPS plug to reduce radio interference. All 4 wires are connected to all 4 pins and the 2 unused ones are left long inside the cigarette lighter plug so you could connect data up to them if you want.
