2009 chevrolet malibu lt2 nuvi hardwire

Well on some units...It does NOT need 12v...Inside the cigarette plug adapter it can step the voltage down...Like on newer sirius units...They only need like 5-6 volts...So the easiest way to do it...First look at the cig plug....Usually they list the voltage and polarity on the plug somewhere...So if you do not want to hack the harness...Simply wrap wires around the cig plug...Pay attention to polarity...But normally the tip is +...and the sides are negative...So wrap a wire around the tip...Tape it up...Do the same w/ the negative tabs on the side of plug...Wrap wire around and tape...At this point you need to find the Accessory wire in the ignition harness...And the wire you wrapped around the tip will go the acc wire...The wires wrapped on the sides will go to ground...Normal GM colors are orange and brown for accessory...Will look up your vehicle and post colors...This way if you ever want to re-use the cig lighter plug(in a different car) or the nuvi...Just un-hook ...My 2 cents...!M.E.C.P & First-Class

BTW...There is usually a fuse inside the cig plug...But just to be safe...Make sure you fuse the + wire going to Acc...You can use two female spades...The fuse legs will fit perfectly into the slots...! So cut the power wire from cig plug(the one you added that goes to Accessory in car...!)...Crimp a female spade on each side and insert the fuse...! Hope This HelpsM.E.C.P & First-Class
