The newest version of the maop disc cannot be read by the Mk4 unless you have OS version 4-1/100 loaded (V31 OS disc).

So load the Os

Then insert the map disc to view the map.

And what is the version of SW with modified splash screen?

Splash screen could not be separately from the SW, means you have two SW disks - v31 and with modified splash screen! You should find out what is the version of SW with modified splash.....

Hi,

Want to make sure I have downloaded the v31 zip file, unzipped it and burnt a CD correctly before I try running the update. The CD shows 3 files:

• Image, BIN file – 294,915kb
• Image TOC -1kb
• Image Cue – 1kb

Is this correct?

Regards,

Marcus

yes, but note that you don't just directly burn these files to a disk. Those are image and control files and are used by burning software to make a duplicate of the original disk.

Thanks UCrewX5. So what do I need to do next?

Forgot to mentionm, my Navigation is a MKIV

Open the BIN file by program which works with image files (MagicISO, ImgBurn, UltraISO etc) and burn this image on the lowest speed to the disk

Mode1 on a MKIV burned using IMGBurn worked perfect!

MK4 can use any mode - 1 or 2.

MK3 use Mode2 ..... and ONLY Mode2!

Hi folks,
First of all, thank you so very much for such awesome info on our NAV systems, y'all have been huge wealth of information and for that i'm very appreciative.
I have a small issue. My setup is follows:
2006 M3 with MKIV Factory NAV.
Car came with ver 4-1/60.
I upgraded to V31 (4-1/00).

I'm able to get into perspective view, but when i do, i have no street names showing up.

Do I need a new map disc for this info, or should i have done an incremental upgrade to v31 from V26?

Would love to get some input from you folks on this.
Thanks!

Jake
