That's cool! Do you have a link to a specific model you're talking about? Thanks.I added an Alpine MP3 changer to my stock deck (Bose system). You'll need to get Alpine's FM modulator. There was no quality loss at all using Alpine's FM modulator. Some modulators muffle the sound or distort.
Cool! I found this model: CHA-S634Just check Alpine's web site. They only have one MP3 changer. You'll need to get an Alpine AI controller FM modulator (comes with a remote too which is cool)--they may only have one modulator too. So it should be easy to figure out what you need.
