if you have an mk4 system yes indeed...mk4 reads all media's +r, -r, dvd, cd, dvd-rw, cd-rw

Yes,MK4. Thanks,great

When I go to the SET menu,I see "SW 4-1/xx WWW.NAMEOFTHESITE.COM"
How I can delete this copyright? I dont need this.

And one more question:
Have BMW V31 Navigation Software.iso all last updates or only new?

For example I have bmw with very old software installed. Can I only update with v31 image or I need to install 29, then 30 etc.

Download a copy of v31 from this web site, the one you have has been modded.


No, v31 will update from any other older version eg: v21 -> v31 = OK

Great! Thanks for the answer!

How I can enter the service-menu to set Perspective-option on? I have press MENU-button for 10 sec, but no menu has appeared. What is wrong?
The MK3 and MK4 menu opened in the same way?

Press MENU, then go to SET (or SETTINGS), then very quickly press and hold MENU button...... Service menu should appear....

In Service menu scroll down and one click down more (till the screen will change to the lower Menu items) and you'll see Perspective.. switch it on...... then go to GPS-Navigation, select Map item, then again press right monitor button and in popup menu select Map positioning and there you'll see Perspective

Thanks for useful tip!

I am going nuts! I have tried to change the map colour of "green area" since it is a very "weak" green colour. Although changing the green area in all Col_roms to the one next to the original green it still wont turn over to the new colour in "fullscreen Blue" but it works in any other setting (Split Blue, Split Brown, Full Brown). What am I doing wrong?

Also, when changing the background sky image (to anyone but the original) my MKIV will reboot after a couple of seconds of displying the new setting. Wierd, huh?

It is not a bad cd-writning, this I know.

Working with V31 navboot and Navtweak 2.6.

Hi Emmet, welcome to the forum,


Don't know about this one mate!


I had the same thing, here is what to look for...

Check the sky gif size, the navboot file is larger in this release of the OS, beacuse of the dual layer changes, so make sure that the sky.gif is the same or less than the OEM sky and that the navboot file stays around the same size after the mods have been done.

This includes any changes to the splash screen, try and keep the file size down, the same as OEM if possible

I had to do a few updates before I found this little gem out.

HTH.
