I had the Sony (don't know the model #) MP3 player in my 4Runner. It was very user friendly, had something like 45w per speaker, and you could scan through different folders on a CD-RW. Also came with a remote. Then only thing, and this isn't a very big thing, is that it would only show like 7 letters of the song title that it was playing. i would have liked to have it display the whole song title.
Just my .02
