I installed this unit inside the headlight housing of my Yamaha V Star 950. After carefully studying the motorcycle wiring diagram, I learned there is a pre-wired connector for an optional light bar accessory. Since I wasn't using the accessory light circuit I determined it to the perfect location to tap into the motorcycle's electrical system. And the light circuit has power only when the engine is running so tapping in there will prevent the GPS from drawing power from the motorcycle battery when not in use.

There was just enough room inside my headlight housing to insert the 12V power transformer with the USB connector threaded out the back of the headlight housing. Next I plugged the USB connector into my GPS device mounted on the handlebar and cranked the engine. Viola!

I have no clue what would cause some GPS devices to switch into data mode. But my Nuvi 255 correctly switches from battery to direct current mode when the engine is running and switches back to battery power when the motorcycle engine is turned off.

My GPS intermittently switched from charge to battery mode in use on the motorcycle--in other words, the power supply was intermittent. Then after proper installation and very little riding for three months it DIED. Checked the mini-USB connector: the metal shell was not connected to ground and two of the connector pins were shorted together. Also discovered the power cable is not shielded and has very light-gauge wires in it compared with the wiring out of the cigarette lighter charger that Garmin supplies. Cannot recommend this unit. Buy something better. Installation on a motorcycle ain't so easy. You don't want to have to do it twice.

UPDATE: Disassembled the Garmin cigarette lighter power supply, put it in a plastic box and wired it into the motorcycle. Now have steady power.

Used this to power my Garmin Nuvi 760 & 765. Anyone with decent techincal skills will be able to intall this perfect. Connect the red wire to 12v switched power. And Black wire to ground. Make certain 12v source is switched power to prevent a battery draw. Which will kill the battery if the Nuvi is attached while the car is parked.

I ran the wire to the glove box to keep the garmin chagred and ready to go when i need to use it.
