But, you might want to wait a few months and get the 9.1 dvd, it should come out in Sept/Oct. And, on ebay - be careful. You may end up with a copy which may or may not work properly. Always email the seller and be sure you are getting the original disk. Quote Link to comment Share on other sites More sharing options...
MBman Posted July 9, 2009 Author Share Posted July 9, 2009 does the disc have to stay in the Nav unit ?? and where is it on my 2007, there is a vague picture in the manual but it is confusing. Quote Link to comment Share on other sites More sharing options...

Yes it stays in all the time. It located in a dvd player in the back right hand side trunk. There is a small access door on the right under the mat and door that hides the tools.

MBman Posted July 9, 2009 Author Share Posted July 9, 2009 well that explains why they are not out there to buy, I thought it was a software download. So when the 9.1 comes out someone will sell me there 8.1 :D (hint/hint) Quote Link to comment Share on other sites More sharing options...
