There are quite a few different Alpine head units that were delivered as stock in the Elise/Exige. I consider myself lucky, I got the CDA-9820XM with the iPod interface... so I have AM/FM/XM/CD/iPod, all from the factory. The display is not as bling as the latest Alpines, and it's only got 18W/channel (and I've solved that problem with a 600W), but I really can't justify the hassle and expense to upgrade to a newer unit for a marginal interface improvement, and not much else. Upgrading your speakers and adding an amp are likely to improve the stereo more than an upgraded head unit.
