Hi guys. I recently bought a Griffin AutoPilot to serve as an in-car charger for my 3GS. I see that there's also a jack built into the AutoPilot for an AUX/cassette adapter. I am currently using a cassette adapter, so do you guys think I'd get better sound quality by going directly into the cassette adapter via my iPhone's headphone jack or by putting my cassette adapter through the AutoPilot's jack (which would then go into the phone)? Thanks again!
