RNS510 wizard req'd in Manchester

Looks like my next car will be a Golf GTD with a nice RNS510 in it, but already being familiar with the car, I know that it doesn't have the bluetooth module, nor does it have full postcode search - clearly I'll be wanting both sorted asap after I buy the car.

I know people will say "just do it yourself!", but the firmware updates look like a complete minefield, and I can't be bothered routing cables under and around trim for the bluetooth module.

Does anyone know someone who does this sort of thing professionally, and ideally would offer it as a mobile service so I can get it done while I'm at work ?

They need to be good, not charge the earth and be prepared to travel to South Manchester to do it.

Any recommendations ?

Thanks,

Jake
