    Cool Designing MP3 CD Car Radio-Need Ideas

    We are really creating a MP3 equipped car radio/CD but need to know how the users actually use their MP3 stuff. What functions would be important, i.e FF, REV, Scan, Shuffle, etc? What information should be displayed, i.e.,track number only, title, artist, etc.? What type of file/folder structure should be included, i.e flat file format with random play? Give us some idea of the minimal functionlity and feature set AND your wish list. Reply and your thoughts will be factored into the design process for new MP3 equipped car CD radios

    The whole benefit of having MP3s is the smaller size of the sound file. Being able to have 100 songs on a CD definitely makes it a lot easier to find a song to listen to when the DJs won't shut up during the morning drive. But, as more people get into MP3s and collections grow larger, there will be a greater need for CD changers, or better yet, DVD changers. I am planning on ripping 5,000+ songs to MP3, and to use a CD changer, I would need at least a 50 disc unit to hold every CD I put MP3s on. As far as how to control, etc. regular CD controls are fine, but the advantage of the ID3 tags needs to be maintained. A simple readout, similar to what many people have already built for their computers (like a 40x4 LCD) would probably be best for most people,and should probably be part of the in-dash display.

    I don't know if it's possible, but what i would really love to have would be a system that had a standard hard drive that I could quickly remove from the car to easily "freshen up" the music or even upgrade the hard drive whenver i wanted.

    I don't think the hard-drive would have to be big, I have a 1G drive, with 700MB of MP3s which comes out to about 300 songs. I never really listen to that many songs. Since multi-gig drives are pretty much what you get these days that seems more than enough for most folks -- I would think, but I may be wrong.

    One of the big reasons I built an MP3 player for my car is to trash the CD changer. My wife still has a changer and it's a big annoyance since I'm use to accessing any song on my hard drive instantly, as well as being able to setup playlists that would otherwise span CDs within a changer.

    I could see having a changer in addition to a hard drive for when you go to visit your buddy's. However, personally I would never use a changer, and would prefer a single front-loading DVD or CD drive.

    Also, it should be able to play regular audio CDs as well

    And I'd love for it to have an ethernet card.

    The only commands i use on my player are:
    - scroll up/down
    - browse forward/backward
    - multi-select/play
    - next/prev
    - stop/pause

    I like the ability to retain the concept of "Albums" and the ability to create "mix" folders, hence the ability to browse.

    for display:
    - folder name if applicable
    - songname/filename
    - elapsed time or time remaining

    I don't care really for all the other stuff like track number and etc. and I don't want to have to create tags for all my MP3.

    Thanks for all of the suggestions. We are looking at a relatively low cost CD/radio/MP3 in dash player to start with. User comments and wish lists are very important and are being heard in our design process. So keep the good words coming, with respect to functions to include, displayed information, and how you use MP3.

    One thing I would like to see and what I'm designing into my own MP3 player is random play with no repeat. If you could set up the system to play every MP3 on the disc randomly without repeating one, and then start the process over that would be great.
