Hi guys, got my first car. Panda is a nice little car. I wanted to attach AUX cable, so I pulled radio unit out. then I noticed red cable behind the radio, nothing connected to. see photo. then I traced it to the back of glove compartment. is that a fuse box? see attaches photo. the cablr was connected to the red cable on the right of that box. shall I be worried? everything seems to be working fine.
