Hi, It happened twice now that I walked past my parked and locked Mk IV Octavia and I noticed that the infotainment system was on and the radio playing.  Anyone had this before?  Both times it was on a sunny day, so quite warm inside the car.  Is there any way so that the infotainment system can only be switched on with a key present?   Car is from Sep 2020 with 1941 software version.   Thanks, Peter
