Polo GTI Interior Trim - HELP

[grem]

hi all,
can someone please help me find where to buy (links if possible) the black interior trim pieces that come in gti and r line model polos. I have a moda and the standard trim is a dull matt black, looking to replace it with the gloss black parts
they surround: the vents, headlight switch, head unit and ac controls I believe. I mainly just want the vents and headunit, but id like the other bits too.
done my best to outline what I mean in a photo below if people dont understand
cheers
