The Aerial above drivers door on my KR is snapped off, what is involved in replacing it? Does it just screw off and swap or is there more to it?

Whats a decent price to pay for a used one? and are TR/TS/KR/KS all the same?

Cheers.

unscrew and pull the lead... if it's anything like a gen1, the lead is 1-2 meters long and it plugs into another extention lead under the carpet near the drivers seat.

might be worth tieing another wire then pulling it through so then you can get the new antenna down the a pillar easier.
