Burning software image problem

[fonz600]

I am a new owner of a X3 and came across numerous sites that u post on about the sat nav software.

The software on my car is 4-1/01 but unsure which one it is and seems to run in 2 languages at once.

To try and sort this I was hoping to download and install the software on here.

I tried downloading 2 files - Night mode with amber logo and the M logo files.
I downloaded imgburn too, however whenever I try to burn the image I keep getting a "Invalid or unsupported image file format - Reason, Only single track images are supported. Do you have any idea why I'm getting this error?

I did burn the image using Nero but nothing happened when I followed the instructions to install it.

Appreciate any help u can give me.
