Oh that's a prick mate, coz that worked for me, and is continuing too work.
One thing too keep in mind, is that a lot of people think that you have too remove the guard/fender in order too remove the antenna, and you don't.
Remove:
1.) You just undo the panel on the passenger footwell.
2.) Then disconnect the antenna from the wiring harness, just above the PCM.
3.) Set the antenna too it's fully retracted position.
4.) Remove the nut, retainers and screws securing the right hand guard/fender INNER, and remove the inner liner.
5.) Remove the screw connecting the earth braid to the inner fender/guard terminal
6.) Disconnect the antenna wiring harness from the main wiring harness connector in the wheel well
7.) While supporting the antenna assembly, remove the antenna support bracket attaching bolt
8.) Remove the antenna lead grommet from inner fender/guard panel, and pull lead out from passenger compartment
9.) Withdraw antenna down through bezel and remove, complete with leads, grommet and bracket.
Re-Install
Reinstallation is the reverse of the removal procedure, taking note of the following:
1.) Ensure cable and harness are routed correctly
2.) Ensure that antenna and earth leads are routed correctly and securely connected
3.) With antenna pushed up against stop in bezel, tighten antenna bracket to inner fender/guard panel, attaching bolt to the correct torque specification.
Torque specification for antenna to inner fender bolt is 5.0-12.0 Nm (Just make sure it's secure basically)
4.) Check antenna operation and radio reception.
I haven't had too replace one before, but they are the exact specifications, pretty much word for word, and I would've included some pics but I'm on my bloody iPad, and it won't let me upload photos for some reason
Anyways hopefully these directions will help you too get it done without having too remove your guard
