Welcome to the forum.

Those instructions are for writing a disc not reading a disc.

There is no .iso file on the disc, the iso file is the disc, compressed into a single file that is then saved on to your hard disc.

You then use this compressed file to create new discs.

So procedure to read, (i'll asume you have imgburn installed)

run imgburn,

Set mode "read" (third tab, along top)
Click on the destination (browse for a file icon)
Type in a name (in any dir that you want)
Put cd/dvd in drive
Press bottom icon (that looks like a cd-> cd on paper)
That will read a dvd and write it to a iso image (on you pc)
Eject dvd.
Close imgburn

So procedure to write,

Open imgburn

Set Menú Mode - ISO - Write
In "Source - select a file..." - click on the icon with the yellow folder
Select "C:\filename.ISO" - Open
In "Destination" it will show the model of DVD recorder, if you have various select where you want to record.
In "Settings - Write Speed", select "1x" (i go no higher than 4x speed)
Put a blank DVD into DVD recorder and "imgburn" will activate the gray button bottom-left to record it

Hope this helps

Thanks - I finally figured out that I needed to create the ISO first but for some reason ImgBurn couldn't write it sucessfully. I was able to do it with DVD Decrypter and it worked fine.

i have burnt over 10 dvd with all kind of program. it burn thr file to the dvd my lap was able to read it but my nav dvd player couldnt, please help. thank you very much

Your problem is probably DVD media that you use, My MK IV only likes DVD-R and Verbatim

Personally I think media plays a small factor. you'll need to burn using 4x or slower and DVD-R... I havent had any luck with DVD+-RW nor DVD+r

Same problem for me with 2008-1. I burned a few DVD's over the years, but 08-01 won't work. I never had such problems. Tryed + and -, RW and not RW, a few manufacturers, other ISO's, mount ISO, make a new one out of it... Nothing helps.

I buy it now. Damn...

i will try to buy some other brand of DVD-R to try it again since everyone says Mk IV hates MEMOREX DVD-R...... AND I HAVE OVER 50 OF THEM......

actually, you may want to make certain you have the correct version of the map disk for your car. there is High and Premium...

i am driving M3 with MKIV so should i use the high or premium version of it?
