ML GPS antenna

How do you install the ML GPS antenna ? I just received one today and it seems that you need some kind of special tool to install it. As I bought it used is there someway to bypass using regular tools ?

The tool came with my antenna. You should check with your dealer they may have a spare one around. It is just a half-moon shaped wrench stamped out of steel. Can't be that expensive.

Thanks, BTW the steering wheel that you sold me came in 6 weeks after you sent it. I don't know why it took so long, but it came without a scratch.
