Hi, I have a Garmin Nuvi GPS unit which plugs into my car cigarette lighter. On the one end it is a 12v cigarette adapter and on the other end it is a mini-usb. It looks kind of ugly with all the wires hanging out. My idea was to purchase an extra 12v cigarette wire/charger for it and hardwire it to my car and run the wires behind the dash, but I don't know how to hook it up.
Can I just splice the wire into the 12v ignition power wire that runs to my stereo? Should I splice it in to the back of the lighter??? Will it have a positive and a negative? How can I hardwire it so that it will have current when the car is on (key is turned). I just installed a new receiver, so I am kind of in the zone right now as far as where all the wires are, so if anyone could provide some info on how to do it, then that would be great.
Just to reiterate, I want to buy a 12v car lighter to mini usb to power my Garmine GPS, cut the cigarette end off and hardwire it to the ignition so that it is powered when the car is on... How could I do this and how would be wired??
hardwiring 12v (car lighter) GPS Unit? How?
