Problem burning mp3

recently i started to have a problem with burning mp3 as audio cds. i burn my mp3s (as an audio cd) to play in my car but they play only in order i cant skip around the cd or play them randomly.
i know store bought cds work in my car and i was able to play home made audio cds till recently. can it be a problem with me updating my software ( i recently updated nero to latest version).

Could it be that your mp3 collection has been written in one big track ? Try writing in “track at once” modus if this is the case.
