The latest version of the MFD2 software that I have is version50, North American DVD version only. It corrects some bugs and removes the"Accept" screen when you first start the radio. You can alsoremove the Accept screen by changing theinstrument cluster coding to Great Britain instead of US. This also eliminatesthe door chime and lets you do the 4-headlight mod if you have OEM HIDheadlights. See 1000q: 4 high beams onheadlight for details.
First check what software version you currently have. Do not load thesoftware update if your head unit software version is newer than the update. This update will not update your map. You need a new map DVD or map CD forthat. The European maps are by TeleAtlas. The North American maps are by Navteq.
The last two digits in the highlighted listing is the software versionnumber. In this case it's 28. I couldn't play audio CDs in the DVDheadunit. You need version 47 and newer to do this. *NOTE: My screen shows Germany/Europe/Europe because I set my instrument cluster to Great Britain. This is a North American headunit.
Insert the update CD into the slot and press load if the cd is newer than theversion you have. Otherwise, press cancel. In my case, it took alittle while for the CD to load and get to this screen.
