Road Angel 7000 .cdt maps

Hi

I am trying to find recent ".cdt" maps to work with RA7000, as the
ones that came with the product are out of date. Does anybody know of
any other product that uses the same maps, so that I can use them with
Road Angel?

Also, does anybody know how i can use nokia maps that are in the .cdt
format with RA7000? I did try downloading them from the nokia map
site, but they come in tiny little sections and i cannot find a way to
join them together to make one large map. Any pointer/help would be
much appreciated.

Finally, does any one know how I can import speed camera data into RA
by doing some tweaking?
