Need advice on MP3 or Ipod?? player

I just found out I can run an MP3 type of deal on my Goldwing through the stereo. The CD changer for the bike is $1000. I ordered it but if I can find an MP3 player that will work I'll go that way.

I would like it to power off 12V
I want a remote so I can hide the player

I have zero knowledge on this type of thing so hopefully someone here is into it.

Thanks Brett
