In my limited research it looks like the Mach 460 with 6 CD changer that came in the car will not allow an aux input. I'd like to be able to get my XM radio and hopefully an aux input for my ipod as well. What options to I have? I wouldn't be opposed to an XM ready receiver as long as it's got a decent display. Thanks in advance!
You can take a gamble on the many ipod/aux adapters and hope you find one that will fit and work with your factory radio. Or you can buy a $50 wired FM modulator from Circuit City like I did and be done with it. It's not the best, but its the next level down from it. Good Luck!
