Nissan Primera P12 Sat Nav Maps Update

I'm quite happy with my 2005 P12 Primera SX 2.2 dci for over two years now despite replacing clutch last month and other bits and pieces...I'm also new on this forum and this is my first post-topic, so getting to the point:

Stated above model comes with built in SAT-NAV that would be often extremely useful for me due to character of my profession. I tried it already and is much better than TomTom or mobile phone which keeps falling under seat on every roundabout or loosing GPS signal. Unfortunately its still 2005 Maps Version so It don't have any roads that were built after that date which results in System getting confused and myself lost  - bottom line is I can't really utilize my built-in SAT-NAV without updating it first to recent Maps Version ...

I have been reading NPOC forum posts on anything related to subject of P12 SAT-NAV for some time now and that topic in this link: http://www.npoc.co.uk/forum/nissan-primera-p12-birdview-navigation_topic51425_post772965.html was closest to solve my problem but unfortunately none of the links in there that supposed to let me download updated maps works anymore.

Downloaded it with jdownloader which downloaded 16 WinRar bits and automatically extracted them into two files in one folder - one is MDF File and second is MDS File.

I did install ImgBurn also and I know that disc should be Dual Layer Verbatim burned at slowest speed. Im almost sorted then...I just need to be sure which file(s) exactly I should burn on to the disc ?

- MDS ?

- MDF ?

- Both ?

- Folder that contains those files ?

I have burned that to "Verbatim 8x DVD+R DL" using ImgBurn by clicking option "write image file to disc" and selecting MDS file in 3x burning speed.

I would like to thank you all for your technical support on that matter
