I'm wondering if an iTrip user could advise me of whether the device works more effectively with the car aerial raised or lowered. The reason for my question is that I have just bought a second hand vehicle and the aerial, which is fixed on the front right side of the roof (the right hand side being the driver's side in New Zealand), is jammed in the lowered position. I'm wondering whether I should budget the cost of a new aerial when I decide whether to buy an iTrip. I figure that having the aerial lowered might affect the receiver's ability to pick up the iTrip signal but, on the other hand, it may lessen interference from other FM broadcasts. Any thoughts, anyone?
