I have a 2001 X5 4.4 and wish to connect my Creative Labs Zen Vision M mp3 player. I know that there are limitations due to the pre-2003 stereo. I do not have DSP/Nav/CD Changer/Cassette...just the basic system w/ single disc CD.

Has anyone had a chance to test the USA SPEC Auxiliary Interface from Crutchfield ($69.99)?

Is this a good alternative?

Thanks
