I'm about to join the GTi fraternity on monday when my new GTi arrives (diamond black)

, and had a question for the experts out there.
The dealer fitted cruise control seems to be a bargain at £150 (much cheaper than a Road Angel!!)
Has anyone had it fitted? And, does it just work like traditional cruise control (keeping the car at a constant speed) or does it have a 'limiter' on it as well, where you can drive 'as you like' until you reach your desired speed, and it then stops you going any quicker?
My Mrs' Merc C220 has this and its a nice touch. I know the GTi MFD has the 'beeper' that goes off when you get to a certain speed, but wanted to know if the cruise control had this 'limiter' feature as well.
Cheers
