What is the best way to install Sirius Radio in a 2006 Chevy Malibu with a factory radio?

Not for sure if the 2006 malibu will have the aux jack in the front of the stereo or not but if it does then you can get a 3.5mm stereo jack at radio shack and plug into the audio out of the sirius and into the aux on the face of the radio. If you dont have the aux plug then you can install it per the instructions. However since the FCC has nocked down the wireless fm modulator strength to almost nothing you more than likely will have static. Ive gave up on installing them trusting the wireless fm modulator will work good enough and now i install all mine with a hard wire fm modulator. (unless the aux jack is avaliable of couse) Ive had good luck puting the antenna as far foward on the dash so it can get signal thru the windsheild. Hide the wire is usually pretty easy
