Has anyone had a dealer retro fit MDI

I am playing with specifying a new company car. I'm looking at an SE Greenline Estate.

I can have either MDI or metallic.

I can live with a white car, with the sunset glass and an MDI but would prefer Steel Grey. However, choosing metallic means no MDI. I've seen on the Octavia forum, people fitting it themselves but wondered if anyone had gotten a dealer to retro fit it for them?

The SD card reader I tried on the demo car was poo - it only saw half the folders and you couldn't mix outside of the folder you were in. I've seen some computer boffins in other forums explaining how you can overcome these faults, but I'd rather have the ease of plugging my iPod into the car.
