Problem with v31, v32 , please help
 

I have an mk4 on a e39 and every time i want to upgrade the system with v31 or v32 , my navigation , restarts non stop , and after it restart a few time the screen block with a image ,

I use only soft for mk4 , but it goes the same!

What should i do?

Welcome to the forums,

Sounds like a corrupted OS to me, or the cd is being burned at to fast a speed.

download the v32 from this webiste and then unzip.

download and install imgburn,

run imgburn and open the v31/v32 image and then select x1 speed (or the slowest rated for the blank cd), then burn.

follow the update procedure and that should do it.

so what is a OS ? you can give me the link to download the v31 or v32
? and what program you recomends me to write the disk because i write the disk with alcoholl 120 but yhe minimum speed is 10 x ,

OS = operating system of the mk4 nav computer

On the navigation monitor, press menu, then set, then look at the top right of the screen, it should have some numbers, eg; 4-1/91, this is the OS version number (not v32, this is the cd release number), if you have 4-1/00 then you are up to date, no update needed.

v32 (4-1/00) V32 for the mk4 (only) Nav compurter

Then use imgburn (The Official ImgBurn Website) to burn a new (blank) cd with the new downloaded OS image.

ok , 10q , so now i have 29,1 because i downgrade the system , it was the only way that he worked, so the problem nr 2 is that my navigation refuse to read dvd with maps? only cd , and i have a dvd map 2008 western and eastern europe , he works a few months ago and now didn t work .

OK, v29 = 4-1/91.

Use method above and this will fix the update problem.

Your dvd laser is wearing out, if it will not read backup dvd's only OEM dvd or CD maps, then replace the laser, this will fix it.

do you know how much will cost me to replace the laser?

In Germany you must pay for a Laserunit only, up to 40€. The complete mechanical costs up to 140€.

The Laserunit calls: SF-HD4
The Driveunit calls: DVD-M3 4.6

10q everybody for help and information,

From where should i buy this unit , From BMW or a computer shop?
