Hi all

As of Saturday I became the proud owner of an '03 M3 Convertible. Firstly I have to say that it is an amazing car - I have always previously owned Renaults with the last being a 225 Megane so you can imagine my excitement!!

I had a couple of questions regarding the Sat Nav and you have to believe I have tried finding the answers but there are so many threads and posts about it that it became a diffuclt task. i am knowehere near up to speed on the jargon either having never owned a BMW so I've done my best to break down what I thinks right.

1) From what I can tell my Sat Nav has never been updated. So first thing is to install V32 which I have downloaded. Even though the deck in the boot is DVD I have to burn this .iso to a CD and install it as opposed to DVD?

2) Then I need a newer version of the map disk? At present I have the original that came with the car. Will this still work with the V32 update just not as comprehensively?

3) Can the latest map disk be downloaded and burnt? I am guessing it can but I'm reading it map slow the sat nav down, urban myth?

4) And lastly, is 2009-01 the latest that will work with my car, I'm readin various threads that if you go 2009-02 you need iDrive Sat Nav? I may have that completely wrong however.

Thank you in advance and I apologise as I am sure this has all probably been asked 1000 times but I am struggling to find the simple answers to this amongst all the threads.
