Thanks for your effort mate but I solved the problem by myself. 
And I'm not ashamed to say I'm ashamed ...for what only I did to myself and didn't figure it out.
Like I said, I was working on those on-board cameras for this mod (and on many other truth be told) and as soon as I install this mod (well copied the files, there's no real installation) I copied also cameras from already edited GP 2005 version. And... maybe you already guess it right... I forgot to rename the damn file. So, instead of having "GP2_2006_cams.cam" file I had "GP2_2005_cams.cam" - INTO 2006 folder ! That couldn't work, obviously. And it didn't. The whole mod didn't show up. Reason I tell you all this is maybe some day some of you will make same/similar mistake and by reading this one can solve it.
Sorry. Thanks for reading. And for the mod of course!
