Hello Wlodar, I feel your pain. I bought my 2016 kadjar two weeks ago today (I bloody love it) but the r-link can initially be a bit of a pain to get upto to speed. first off did you use a memory stick (8gb or bigger) ?did you press the 'connect' button on the r-link screen in your car, found in the hamburger menu (3 horizontal lines) on the homepage. If you have not pressed the connect button you need to do this. If you have it can take 2-3 days to register. the r-link store and the r-link tool box are intrinsically linked. so purchases made in the r-link store (free or otherwise ) will then become suggestible to download in the R-link toolbox.
Im sure others will be along whom are better versed than I soon but I hope some of this helps. enjoy your new car .
p.s. what model did you get , colour etc.
