SD card to play mp3 in Japan car audio

[fengzheng228]

I have a japan car audio player in my car, model is NHDT W55. I can't play an sd card in its sd card slot. Please help me with this problem if any of you know. Thanks a lot.

Are you sure this SD card is for audio, and not for navigation?

I'm pretty sure Alabalcho is correct. That SD slot is part of the navigation system.

I saw memory stick button in audio menu. So, I thought that sd card slot can be use to play music. Seems like there's no way to use this then. Thanks a lot anyway for replyin to my question.
