yeah its called a regular usb cable (the one that came with the Meizu works perfect)
my deck accepts a USB flash drive, hence, why i got the meizu (shows up as a removeable drive rather than some kind of retarted propriatary crap, IE Zune, ipod, etc)
i plug my 8gb meizu into my car deck, the car deck will pull the file listing off the meizu and start playing in alphabetical order, it goes by folder browsing (the best way). also while its playing the meizu CHARGES too!!!
my deck is a JVC KG-G820
the display is no where near as good as my old pioneer OLED display, but a usb port on your car deck is not anything you can live without.
BTW: it only takes 7 seconds for the deck to read 4GB worth of mp3s
EDIT: forgot to mention, even if your not playing off the usb port, you can still plug in like a phone and it will charge it(IE razr or any phone with a usb port like almost every HTC phone) .
if you already made the mistake of buying some mp3 player that shows up as MTP or propriatary format, you have the option of AUX in, i got the add on for $30 shipped, its just an extension cable that has a 3.5mm standard headphone jack, i use it to play the GPS voice from my PDA phone through my car speakers if i need too.
