it is mainly the same program installed already on nokiam 6110 navigator (called there "nokia navigator"), but with same revisionnumbers, and all pictures on the side for route 66 mobile 8 were simply taken from the nokia 6110 navigator.
therefore i can say: for 129 euro you get the program with one map "western europe with nordics" (that includes 22 countries, fits on a 2gb card, and is from q2 2007, navteq).
if you want other maps, for example the maps "baltics and greece", then you have to pay again, most of those cards cost 49 euro each. an overview on maps available for nokia 6110 navigator is here:
https://secure.66.com/store/ , so I guess those maps will also all be available to download and install on route 66 mobile 8 for other phones. prices are also listened there.
