Up till now I've been getting by with a Gigaware FM transmitter that plugs into my cigarette lighter. It gets the job done, but whatever station I tune it to (even one of the few "empty" stations) it starts getting fuzzy (losing FM lock) after 10 seconds. My car is a 2005 Malibu LS with the stock system in it and I want to find a [rather inexpensive] solution that's better than what I have. The head unit is just a cd player/radio with no other external input. I read that the unit should be XM ready, though I never checked.
What I'm asking is if there is a way I can add auxiliary audio input to my car without too much investment in money. Primary reason for wanting to go this route is that I'm uncertain how long I will have this car before I decide to get a newer one (at least 1.5 years, but I just might drive the car till it quits).
