I think you need only look at the 2008 5 series. iDrive is standard, Navigation is optional. Don't confuse one with the other. iDrive now means interface for all the car's systems such as audio, climate, maintenance info, etc. All 5 series come with the iDrive screen and interface standard equipment. I suspect the M3 will get the same. If you have never used iDrive, don't believe all the nay sayers until you try it. I had iDrive on my 06 330i and concluded that I would never own another Bimmer without it. Actually, I will save two grand if iDrive is standard minus Navi...never used the Navi much but used the iDrive daily to set up the surround sound to my liking, select different audio sources, and now you can even control your iPod through the screen. :rocks:
