2005 Bird satellite radio installation

[woodm]

I have a 2005 T-bird that I want to install satellite radio in. The existing radio is "satellite ready". Has anyone installed a kit in their Tbird? If so, what kit did you use and did you have any problems? I would prefer XM but Sirius is o.k. Of special concern to me is the antenna mounting. Since the car has a removable top and is also convertible, where is the antenna supposed to be installed and does a wire have to be run outside of the car? Any help would be appreciated.
