I think the only one with a built in fm transmitter is the samsung/napster one. Better off buying a dell dj or something, hook it the belkin fm transmitter.

I've never seen a combo unit personally, my preference is the little gizmo I have in each car. It'* an FM modulator that you hook your device (any device including DVDs or Laptops, not just CD/MP3 units and the like, and also has a USB port to plug in a memory stick with MP3'* on it if you prefer.

The beauty is that it supplies the 5V from this USB port if I need to use my laptop accessories (like the cool little snake-light) or charge my PDA. It'* small, unobtrusive, works well, and was cheap. Looks OEM, or close to it. I have one in each car. You can run it in any standard cig lighter.

This is the one I have, but I bought both of mine for 20 something at a couple local stores:

Note that the unit is NOT blue. It'* a good match for the interior.
It can be seen in my 93 in these vids (sorry, no pic, hold on tight, and turn the volume up):

The third time you watch these, you can really see how nicely they hold the nice keychain, and match the interior dash color.

Bill, you got voicemail

Those things look pretty freakin' sweet...makes me wanna buy one...but I already have a system for playing MP3s.

Comes in handy for DVD'* on long trips. Either off the Laptop (the ultimate MP3 source as well) or the Mini-DVD player. If I've seen the movie, I can drive and listen, and it'* like watching it again without watching it. The sound quality, especially in the 93 is phenomenal.

I would recommond head unit that support input from mp3 player. or go this if buying a ipod
