Toyota Corolla iphone usb flash drive adapter integration to radio
Not every Toyota Corolla 2001-2007 flash drive adapter fits year of 2004. Finally found this one which worked: Connects2 CTATYUSB001 Car accessory. It has both usb and aux outputs for flash drive with mp3 or iphone audio out only.
Tip: My car registered on 03/2004, while installing, at the back of the radio was not empty slot but on the cable itself was additional white “in” connector which was matching 1:1 to the white connector on the mp3 accessory i bought, so i plugged it there.
