Anyone happen to know the socket size?
It's pretty large, I have a small socket set and the largest socket I have wasn't big enough.
Thanks!

 

It's on pg av-118 of the FSM, but doesn't say the size.

It does say that you have to be careful when tightening it due to signal sensitivity and the roof may get deformed. Also gives a torque value of 58 inch lbs.

Sorry though....no size.

 

Well that's good to know at least.
Was going to try and install roof overlay myself, but wasn't able to get antenna off. Time to invest in some new tools I guess!

 

If anyone is interested in this it ended up being a 23 mm socket.
