If you are interested in deleting the ugly antenna wart on top of your LR, I just did it and it was pretty easy. It's only attached with some permanent sticky tape, it pries off pretty easily. There are two wires which I just snipped, although after prying off the rear interior overhead panel there only seems to be one wire going through a rubber plug to the antenna, so I don't know why there are two wires on the antenna assembly. I was surprised that the GPS still works, the GPS antenna must be somewhere else, or maybe it is inside the small rubber puck that remains attached to the roof. I never ever listen to the radio so I don't need a radio antenna. This did not trigger any sort of fault or warning messages and it looks much better without that big ugly bump on the roof.
