I purchased a new car and it allows for a flash drive to play tunes that are downloaded on to the Flash Drive.


I have my Library of songs about 8000 at 1411 Bit rate except for the 200+ I purchased from iTunes.


I would like to transfer them (except the iTunes purchases) to the flash drive BUT at a lower Bit rate of 320.


Can someone explain if that is possible and how it can be done.


The Flash drive is 64 GB but that would not be enough storage space to hold all the tunes at 1411 bit rate.

    iTunes: How to convert a song to a different file format - - including information about different formats and discussion about compression.


    This will create a second file that will appear identical to the first one but at a lower bitrate as you configure in the settings.  Unfortunately this is a bit of a nuisance since it get mixed up with the rest of the iTunes files (you can try to isolate them a bit by sorting according to bitrate or creation date).  You can add them to a separate playlist, then drag that playlist to the flash drive.

    In other words if I put 4 or 5 separate playlists onto the flash drive will the car audio be able to read it ?

    Some will, some won't.

    You will need to read the instructions for your car stereo.

    iTunes is probably principally designed to work with Apple devices.  The extent to which it works with other things is fortuitous.  The convert to lower bitrate without adding to iTunes is really a feature of syncing which only works with Apple devices.  All other things you have to find workarounds.  If you're lucky you can find a third party encoder that lets you drag playlists of files to the encoder for batch processing and then put them in a folder that isn't part of iTunes.  I just tried this with my old version of Max and it didn't work.  XLD doesn't let you drag files to it for this purpose.  Some applications will let you drag from iTunes to the application but many won't.
