Radio names and dance arrows (disappearance)

[Gatt]

When I get in my car, most of the time (not all the time) the radio doesn't show up on the screen or it delays for a long time. I switch radios and sometimes I still get this problem on the next radio and sometimes I don't.

Also, the first mission for Cesar where you go on a hydraulic competition at the start, the dancing buttons or arrows at the bottom of the screen sometimes doesn't show up like it disappears then comes back on the screen then it repeats. It's not normal.

I need help because I can't do Cesar's mission because I lose the competition and fail the mission.

Help.
