[Off-Topic] Solution to "Please insert correct map disc" {edit: link is dead}

I own a Toyota Vitz 2009 model which comes with an NDDN-W58 audio system installed. It was a great hassle to get it's stereo working if you get the error "Please insert correct map disc". I finally got it working so I thought I'd share how to get rid of this issue.
Firstly you need to know that there is no known way of changing the language of the stereo system. Also there is no way to be able to run DVD's while the car is moving either. This tutorial is only to get rid of the aforementioned issue.
Here's what you need to do:

1. T download the map disc image, go to http://dh16.com/27454228 (Google Chrome is recommended because this page is in Russian) [link is dead now, will refresh when I get time.]
2. Click Download in the "Free" column in the lower part of the page.
3. A page full of advertisements will open up and you need to click on one to continue.
4. After clicking on an ad, a countdown of 30 seconds will begin at the top which will end with the download link. Click on it.
5. Enter the captcha code on the download page and proceed with the download.
6. Extract the rar to yield the ISO file.
7. Burn the ISO file onto a blank DVD with a burning software at 4x (ImgBurn is recommended).
8. Once done, this will be your map disc.
9. Insert it into the Map Disc slot into your stereo.
10. Voila! The stereo works like a charm!
