newbie with a noob question,thanks guys!

I'm new to this forum, and I want to know some noob question about the navigation system. I have a 2003 E46 M3 with OEM navigation system. I want to know what system do I have and what version.

I checked the menu and setting, on the top right hand side says.... SW 4-1/80 ...does this means I have the MK4 system? but which version? do I have to update to the latest version?

thanks

Yes, you have a MK4 with version .80 of firmware. This is upgradable up to a .00 with v31 disk that circulates around this forum...

Help!!! I just downloaded V31 and burn into a cd...then insert into my dvd navi system,and while it saying loading the screen went black, it's still black even I took the cd out and put the map cd in....

what can I do?

You probably burnt a bad disc with errors on it that corrupted the loading process.
Burn another disc, test it properly (disc scan, error count) before using it. You'll find burning at disc speeds supported by the blank media you use give the best results.
I always check quality after a burn using Nero CD/DVD DiscSpeed, it gives a comprehensive quality report.

now it is getting worse...i just burned a better one a dvd on with very slow speed using alcohol120%...and insert into my dvd navi system...still black screen nothing, so i tried to take out the dvd now got stuck jamed into the dvd...what can i do now?

[msakuraz]

never mind I fixed it by took off the battery and burned a new cd and it worked...but I can't find any difference between V28 and V31

[KiwiJochen]

V31 contains bug fixes and ability to read the new dual-layer dvd maps. There are no differences you can 'see' unless you use the latest 2008 usa or europe map disc
