In Dash Car MP3 Player with 802.11?

An anonymous reader asks: "I'm looking for a car MP3 player, either with a tuner and CD player built in, or with a line-out to connect to the existing car stereo. The Omnifi DMP1 looks good, but you need to use their Microsoft Windows software to upload to it. When you take the harddrive module out it plugs into a USB port on a PC and can be used as a USB mass storage device, but none of the files you copy to it will be put into the database, so they won't play. It's also got an optional 802.11b adapter (plugs into a USB port), but it only works with their software. No SMB, let alone SSH, NFS, or FTP server is running." While this is an itch many of the more enterprising among us can scratch on their own, are there dash units currently available that aren't tied to any particular PC platform? "I looked around some more and found the empeg/riocar, but it was discontinued some time ago.

Yes, I know you can build one yourself. I built a navigation system for my car (which I took out again after my MS degree presentation because it was a PITA to use), and a PVR for my house (which I had a mishap upgrading when the source of TV guide data changed, and I haven't bothered fixing yet). This time I want something that works out of the box, but with a little more freedom for transferring files than I've found so far.

If I don't find a new product with all of what I want, I will either look for a used Empeg/Riocar, which there is a large development community for, and I'd try to add 802.11 and SMB to, or get an Omnifi DMP1 and attempt to hack it's database so I can add music without the WinXP software. Then if that goes well, see about getting an SMB or SSH server running on it (yes, it runs Linux)."
