Title: works fine for me
Review: I also have the nuvi 660 and loke it I got bot of these together because I didn't want to have a problem with connecting to satswithout the antenna I get a 20-30 ft accuracy with it is always less than 10 ft most all the timeI use the magnet and have a 99 F-150 and put it on the roof just behind the center brake light I just took out the light and there is holes and you have to use a small rat tail file to make a U shape in the plastic on the light so the wire doesen't get pinched by it when back in placethe only problem with this is the type of wire used is low to med quality wire some high quality shieled wire there would be less leakage and a better signal
