I have a 2004 4dr Chevrolet Colorado and I am looking to update its audio. Right now I'm just looking for a head that will allow me to plug in my ipod. I looked on BestBuy.com and the compatiblity checker there told me nothing from Best Buy is compatible. I am really SOL? or is there something that is compatible? I have no experience in car audio so your input is very much so appreciated.
