ok here's what you need to do, take the bezel off, take the radio out. Next reach up at the top and feel where the clock is, next you feel the empty spot right above the clock where you GPS antennae will just happen to fit perfectly. All I did was take the antennae and slide it above the clock, don't slide it too far forward (towards back of car) because you will start to see the trim piece and radio move apart. I stuck mine up in there and just left it and haven't had a problem since, as soon as it gets warm out I'm putting my XM antennae there too
