2006 x5: Want to install Intravee II / KCA-420i / DHA-S690

[cve77]

Hello... apologize in advance if this is redundant...

I'd like to install an Intravee II and Alpine DVD changer in my 2006 x5, for ipod, cd, and dvd capabilities. I've read recently that the DHA-S690 is supported by Intravee. I figured I'd get a disc changer that played cds as well as dvds, especially because they're about the same price.

A couple of questions:

- How will the DHA-S690 work with the Nav system? Will it have full DVD movie viewing capabilities, CD playing capabilities?

- I'm tracking down a Intravee II. Do you know if it's possible to update the firmware on a mac?

Thanks!
