Has anyone fitted the Alpine Sat Nav unit to their Skoda?

I'm looking at the package with the screen and separate Sat Nav CD unit:

Alpine Navigation Package IVA-310R + NVE-N099P

Anyone any experience of this please? Is it worth the extra outlay over the standard Alpine sat nav unit (INAN333RS T334)?

Edited to say that the link seems to take you to the wrong page :thumbdwn:

I've got that system in my car (Superb Elegance) , its brilliant , but then I'd say so because I work for Alpine However that doesnt take away the fact that its a fantastic piece of Kit!

You are welcome to see it in operation if you are nearby, I am near Uxbridge, greater London.
