* I have a 4Gb memory stick. Apparently, only the first ~170 songs can be read by my KIA Ceed stereo.

* I can't change the currently playing album using the buttons on the steering wheel. It would be cool to use the [next channel]/[previous channel] buttons but they are useless in USB mode.

Do you experience the same unpleasant behaviours ?
Is there a way to upgrade the stereo system software (in this case, are new versions available)?
