Just wondering where people have installed their Antennas for the Sirius Satellite radio and how the antenna wire has been routed to the dash. Trying to figure out the best option!
Also, has anyone tried placing it behind the stock antenna and covering it with Shark Fin Antenna? Any problems in the reception?

Anyone have a link to satellite radio installation instructions?

Thanks

 

Several people on mazda3forums have placed their sirius antenna either underneath a shark fin, or inside the spoiler (on a 5-door). Neither causes any decrease in reception for the sirius. If you go under a sharkfin then you'll need to cut a small notch in the roof panel for the cord to go through, however the notch is covered by the FM antenna base.
