Just thought I would show you guys what I've done with my car. I have both a sirius radio and ipod going into a pie adaptor. I just split the headphone jack and it works great as long as only one is on at a time. The sirius is tied into the cig lighter behind the dash and the antenna is underneath the top of the dash near the windshield. I have never had a problem with reception and you cannot tell I have a radio when I put the receiver in the ashtray compartment. Speaking of which I took out the ashtray and put black felt and padding in the compartment so I dont scratch the radio when putting it away. The shifter is the mazdaspeed SS and the knob is a razo 250g weighted knob. Hope you guys like it
