I have been reading the forums for the past week as I am trying to update the OS as well as the nav DVD. I currently have the 4-1/42 SW version 24.1 and I plan to upgrade to the latest v28. I also got the DVD disk w/ 2007.1 NA map. The question I have is where do I find the DVD-ROM. Should I insert it into the CD player? I have a 6-cd changer and the main cd-drive is below the nav attachment. The NAV system in my car is the pop-up type.

Sorry if these questions have been answered already, I tried searching but could not find anything specific to the pop-up Nav system in a X3. Any help is much appreciated. Thanks in advance.
