Hi,

First, sorry for my english I'm a french user.

Well, I bought yesterday a 530D (E60) Luxe Pack that was made in 2003 september. I have a prob to identify my Nav System and to konw what is my Nav Os version.

My nav system is only composed by a on dash Radio CD/DVD with 4/3 screen like this pic :



The nav screen appear only with row/voice and use a DVD that is put in the on dash unit.




After readed a lot of posts it's seems that is a Business Nav Model but not sure aubout this.

My second prob is to identify my CIP/Nav OS version because the tip in your faq (turn on car, go to Setting menu and hold Menu button for 5-10sec) seem don't work with this system.

This a screen of what appear when I push the Idrive button :





I tried to stay on the first Idrive screen and hold Idrive or Menu buttons but nothing happen. Same thing in the menu screen above so I can't identify my OS version to kinow if it's possible to upgrade it to use MP3 DVD/CD (because at this time MP3 don't work).

Can you help me please ?

Thank you.
