Where can I get a upto date sat nav cd other than dealers?

[laser4596]

The dealers want an extortionate amount for the sat nav cd's, where can I get the latest up to date versions from? I presume they update the cd's even though they have now been replaced by the dvds?

I couldn't find any cheaper source than the stealer - even going direct to Navteq or whoever that makes the maps. You apparently get a bit of a better deal if you trade your old disc in (DVD is still around £100 though). Other than that there are places you can find the material to DIY it if you're so inclined . . .
