You've got options
Boss packs some pretty cool features into their 752UAB CD receiver. Not everyone gets their music from CDs, so they've included a front-panel auxiliary input and a USB port. You can plug your favorite device into the aux in, or plug a thumb drive loaded with music into the USB port. You can even play music from select Android™ phones through the USB input (USB port not compatible with iPod® or iPhone®).
Fold down the front face and you can slide in your favorite CDs, even discs burned with MP3 files. And you'll also find an SD™ card slot behind the face too, so you can slip in a card loaded with MP3 files and enjoy the music whenever you want. Finding songs on your media is easy, thanks to an alphabetic directory search feature.
And Bluetooth® too
Boss sweetens the deal with built-in Bluetooth. You can answer a phone call with the push of a button, and talk as if your caller is sitting next to you, freeing up your hands and letting you concentrate on the drive. And the 752UAB supports Bluetooth audio streaming, so you can stream music wirelessly from compatible devices to the receiver, with basic control functions like "play" or "pause."
