A cracked, loose or missing mast, or GPS that keeps losing its signal, can mean the antenna needs replacing, though a fault elsewhere in the system can look the same. Find the cause before you replace it: with the vehicle parked and the engine off, look the mast and its roof mount over for cracks or play, and leave signal testing to a shop.
