I sold my X. I have here a Blitzsafe BMW/Aux DMX V.1 DSP Aux Adapter. Works with E53 that has DSP. This adapter allows you to input an external device to your factory radio. It emulates the CD changer. It is in very good condition and works perfectly.

I am selling for $65 including shipping (I cover shipping via USPS). U.S. sales only. PM me if interested. I prefer PayPal for payment.
