Specifically for my 08 mustang GT? I've looked around, but other than adapting a magnetically mounted one I don't really see any options that would work on my car. Ideas anyone?

This car also has built in Sirius satellite radio, is there an adapter to use this as my GPS antenna (As I have no plans to ever use satellite radio)?

I think I've thought and now bought most of what I need to set up a fairly killer carpc, this is the only real part that's still baking my noodle so to speak for how to integrate properly. Not only for the best reception/transmit range, but for the stock look.

Integrated router: should anyone with this knowledge have read this far, is there a good one for setting up a Virtual access point on, so it can not only be set up to connect automatically to a set and/or open access point, but also function as a local access point itself at the same time for say a laptop in the car?

Thanks,
Wayne
