Ive got that panasonic H/U, just without the mp3 function. U can program preset radio stations but pressing the up and down arrows on the right side of the h/u. u jus have to press up and down instead of press 1 2 3 etc etc. Personally I would rather go with another h/u panasonic makes that is just like it but is so much better. I want to trade my h.u for this one.

Why u may ask would I buy this over the other one u wanted?

Well its got so much more movies. They are so much better than the old one . Also this one has still pictures so if u get bored of the movies, u got those. Its so much more sexier. All the controls like when u go into setup are a lot better animated. Plus not everyone has it. Also another thing is this h/u only has 2 5v preouts instead of 3 like the other H/u u wanted.(Sub, Front and back instead of Sub, Front, back, Aux)Thats the only downside to the one i reccomend
