Update!
Managed to get a few jobs done at the weekend. New rear cup holder in place (after a bit of fiddling), along with factory mats and new bluetooth module. Bluetooth install was a breeze - literally 30 seconds and I had my iPhone connected.
As a result, and because it stopped raining/snowing for an hour or two, I managed a bit of a clean and polish:



I also installed some number plate LEDs (again, a much easier job that I might have thought).
Next up will be the rear Golf R LEDs. Can anyone recommend a reputable source?
Thanks.
