sony CDX-GT420U headunit
front AUX port
front USB connection (play music from USB drive)
remote control
no longer needed as sold car
slight faults:
the forward (to next song) button is jammed ( may be able to fix this, but i just use remote)
havnt tested radio
havnt tested CD player - last time played CD , songs skipped, but havnt got any cds to try (or car to try in)
usb connnection (play music from usb stick ) definitely works fine - this is all i used it for
hence price, no offers, cost well over £100
