Updated Nav CD

Does anyone know how much it is for the latest Nav CD for a 147 GTA. I'm guessing it will be mega expensive from the steelers, is there anywhere else I can get one from??

Edit - its £77, they have a "sale" on. Still too expensive, IMO.

NAVTEQ: Home

Hi i have a 2003 156 gta. I have Navigator but no CD. Do i source one from the same place above? (navteq)?

There's a thread on a possible group-buy-ish-type-thing for this in the ICE forum.
