i'm old. i don't know what's going on. how do i connect my iPod to my truck stereo. it's a 2000 dodge ram with a factory stereo and the original owner installed a disc changer behind the seat. i tried plugging in the 1/8" stereo cable from that to the iPod but that doesn't work. the cd player only works on a certain radio station fwiw. i'd like to wire it directly for the best sound quality as opposed to tape heads and transmitters. the factory unit doesn't seem to have an aux. connection in the back...what do i need to get it connected? i also have a sony cdx-mp40 that my kids left here in storage and it does have aux...but then i'd need adapters etc. if i have to buy a bunch of adapters and converters and chargers would i be better off buying a newer head unit with usb capabilities and can i find them cheap. i don't want to spend much...i just want to listen to lectures and audiobooks while i'm traveling and need it to be fairly clear since i'm hard of hearing and my cab is pretty loud.
