Yes, I'm worried about the lack of a true aux input also. I'll have to check with someone who's installed one before. Has anyone tried using the CD/MD changer inputs as a generic aux input?

As for skipping on the CD/radio unit altogether: although I doubt I'll use the CD player often, I know I'll use the tuner quite a bit, and I think the convenience of having a stereo even when the Empeg is out of the car (for whatever reason: uploads, upgrades, repairs, loaned-out) makes the $300 expense worthwhile. Keep in mind that there are many places on the net that sell these units for substantially less than Crutchfield.

Thanks again,
Oscar
