Ok this is what your going to want to do if you want it on the roof near the windshaeld. pull off your a pillar, remove your driver side sunvissor , and any kind off mid vissor or mirror and the head liner ring around your sunroof. Mount the antenna in the middle of the roof close to the glass and run the wire thought the sun roof under the head liner past the sunvissor mounts and down the a pillar to your wheatherstripeing around the door. reinstall your head liner ring around your sunroof and mirrors,vissor and mounts removed before. tape the wire to the a pillar and reinstall the a pillar. run the wire under the dash to your tuner box mounted behind your glove box or under your driver seat. I like it behind the glove box so no one can find it. dont worry about the wire coming thought the sunvisor it has rubber pading and wont cut or crush the wire.
