After many tries with phone mounts on my LHD ND, including MX5things' own one (sorry, Sergey!), I found the best one to be Germany's IL Motorsports, which is mounted just to the side of the screen. Onto it a number of adapters could be fitted. Photos show the one that comes with it.
My public request to Sergey: please make an adapter to fit the Nillkin Qi charger, like you did for your own mount. Thank you!
