Your satellite antenna only works for the Sirius radio. It won't work for the GPS signal for navigation. You'll need a separate antenna for that. As long as you can find an adapter (if you need one), then the antenna will work on whatever Sirius receiver you get.
BTW...what aftermarket radio did you find that has bluetooth, navigation, AND Sirius? I haven't been able to find an aftermarket radio with Sirius built-in. Seems like they all require a separate receiver.
