Ive got the small flat antenna that is mounted on the top rear of the 4runner....the first question i asked the salesman b4 the install was will this be ok in a touchless carwash...he said..yes. Of course after my first wash with it, its flapping all over the place. Its stuck on by adhesive. I love the satellite radio...dont have time to manually wash it.....any suggestions for an antenna that avoids this problem...or do i forgo Satellite radio for a clean vehicle? Will the magnetic antenna screw up the paint? Already checked out the antenna's at the Sirius website and the place i got this from is telling me i need to manually wash the car now! (got this as an X-mass gift) Thanks.......
