I have a DLO TransPodFM, which is a bulky peice of crap FM transmitter. I would highly advise against that one because there is an annoying beeping when you turn up the volume on quiet songs. I don't like the FM transmitter while I am in the city due to static and having to change stations every now and then.
I am getting the IceLink Plus, which should be here sometime within the next week or so. I debated for a long time, but the new IceLink Plus sounds too good to pass up. You can mount the iPod anywhere you want, or get mounts for it to put in front of your vents or beside your console. The cool thing is that the new version now displays (or claims to) the song info on your radio, not just the iPod. You can still control the iPod through the iPod itself, but also through the radio and steering wheel. It adds the whole playlist deal like the Apple/BMW connect kit does, but you can also scroll through your songs in your own playlists, not just preset ones. Besides, everyone needs an iPod. When I get out of my car, I put mine in the dock that is connected to my home stereo. I haven't used a music CD in a little over a year now and I don't miss them at all. Well, that is just my thoughts... http://www.densionusa.com/x/index.php
