I need your advise iPOD Connection or CD Changer
#21
go with the ipod adapter. the sounds from the ipod are much better than fm and would depend on how the mp3 is burned for cd quality. i can tell a difference between fm and ipod even when i'm not an audiophile
on a different note, i heard bmw came out with a cd changer that can play mp3 cd. is this correct?

Wow, I was about to post the same question. I'm scheduled to get my IPod interface installed next week and wanted to validate the quality & functionality before spending the $600. I use a FM Modulator today to listen to my IPod, please tell me the sound will be better than that despite not being CD quality.

Even then, unless you have the L7 or better audio you probably won't hear a difference as soon as you start the engine anyway!
As you mentioned, at any decent bit rate, you'll need a carefully controlled experiment to tell the difference. On top of that,
the vast majority of people's hearing sensitivity falls off quickly around 18kHz. (Mine certainly does, and it is classified as normal.) The audio compression algorithms exploit this phenomenon by eliminating signal that is marginally audible.
Talk about 20Hz-20kHz fidelity usually brings sniggers from my audiologist wife.

I doubt they would even be able to discern the difference then, either. As you mention, road and engine noise pretty much defeat any attempts at fidelity. I have a few poorly-encoded MP3s that sound marginal through headphones or on the home stereo, but sound fine in the car.

As for the <20khz thing goes, here in the UK we use the fact that teenagers can hear a much higher freq range than "grown ups" by putting "mosquito" devices in areas where we'd much rather they didn't congregate. Basically very high pitched buzzers that only scrotes can hear.
Anyway, miles off topic so, don't hesitate, GET THE USB INTERFACE, it's marvellous.

Aha! don't forget that the usb port can read USB keys directly! so if the upgrade is usb+autio-in you can play music straight from usb keys OR from an iPOD (with the overpriced cable).
