[Newbie] - 2009 320i + innvations - iDrive Nav Questions

[dontexist]

Hi guys,
first I will apologise for perhaps asking the stupid and repetative questions.

I picked up my 320i exec and Innovations pack last week.

To the best of my knowledge, I am being told it has a Radio Navigations system. I think the manfactures are Harman Becker. I believe a US based company.

I have V14 Nav disk, made by an aussie company Whereis (www.whereis.com.au). I am told by this company that all relevent info, particularly speed cameras is on the disk.

I was wondering if someone could answer the following.
- make & model of this Radio Navigation system.?
- Is it possible to modify the program (I assume in the unit) to trigger speed camera information ?
- This car uses this iDrive menu system, I assume I can't modify the splash or entry screen. I have read on older systems you can put custom splash screen..?
- Can the view be modified from 2d to 3d at all..?

- does anyone have any experience with this unit..?

I would be grateful for any assistance, thanks guys..
