Sirius Satellite Radio for a 2006 Coupe. Already prewired, need tuner and antenna. Any suggestions where I can get the cheapest price from?

 

Sometimes you can get them used off of people for cheap in the forum or on ebay. You can also try calling your local Infiniti dealers. Otherwise its either grubbsperformace.com or everythingg35.com The price is usually the same on both websites; just different antenna packages.
