I've asked a couple local installers about installing the Avic-D1 in my X-5 and they say no go. I would like to install this unit with the Sirius module and keep my current IceLink. I don't believe i have DSP, but the installers always talked about amps built into the speakers..or something of the such..Any tips or suggestions? Your audio package is a great deal!, but a little more than i need, plus it has the XM module. Good luck selling and thanks for any help!
