how about ease of use then?
if you just get the cable… you’ll have to adjust the volume on your ipod, then the radio. Then go into the EQ on the ipod and make it flat so that your not running the music through 2 separate EQs (the car’s radio’s eq and the ipod’s eq). Get it wrong and you’ll get tons of distortion / clipping and generally worse sound. You like to turn the music up on a nice day with the windows down? (insert: nod head), well with less distortion you can crank it up more!
the total difference in $$$$ here is one quality beer.
ok, I’m done, I’ll leave you alone to the ignorance is bliss.
