I have a 2016 Nissan Micra which has a USB port as the aux input. I would like to play minidiscs from an external portable minidisc player which has a 3.5mm jack output. I would therefore need a jack-to-USB adaptor to do this but I have been told that not all such adaptors will work for this purpose. Can anyone enlighten me, please?

HELLO, I AM NEW TO THIS SITE. I RECENTLY BOUGHT A 2016 NISSAN MICRA ACENTA. I HAVE THREE QUESTIONS THAT I HOPE SOMEONE CAN ANSWER. 1. THE DASHBOARD DISPLAY OF TIME AND MILEAGE HAS A SMALL ICON TOP LEFT WHICH LOOKS TO ALL INTENTS AND PURPOSES LIKE A PAWN FROM A CHESS SET. UNDERNEATH THIS ARE THE LETTERS "ODO". WHEN I AM DRIVING I HAVE NOTICED THAT A SMALL BLACK DOT APPEARS FROM TIME TO TIME, AND ONLY VERY BRIEFLY, TO THE LEFT OF THE ICON. I CAN FIND NO REFERENCE TO THIS IN THE OWNERS MANUAL. DOES ANYONE KNOW WHAT THIS MEANS? 2. THE DEALER FROM WHOM I BOUGHT THE CAR SAID THAT THE CAR WAS FITTED WITH PARKING SENSORS AND I KNOW I SHOULD HAVE QUERIED THIS AT THE TIME BUT I DIDN'T, HOW DO I ACTIVATE THESE SENSORS? 3. I'VE NEVER OWNED A CAR WITH A USB INPUT. I UNDERSTAND THAT I CAN PLUG IN A THUMB DRIVE AND PLAY MUSIC FROM THIS BUT IN WHAT FORMAT SHOULD I RECORD SONGS ONTO THE THUMB DRIVE?
