I currently have a Sirius Audiovox PNP3 receiver and car kit (including antenna). I am considering purchasing XM (either in addition to Sirius or to replace Sirius). If I get the MyFi, will the PNP3 antenna work with it? Is there any compatibility between XM and Sirius antennas, or are they programmed uniquely to pick up totally different signals?
Thanks.
Thanks.
