~150 Bucks for Destinator (CF)
~100 Bucks for MapPoint (without Routing capability, Streetdeck or CF)
or
10-30 Bucks for "Marco Polo Reiseplaner" Maps
a "small" difference

(I bet there are similiar map formats for US available!)
Okay I must state that I can afford to buy a Destinator Map for 150...
but if I want to give traffic jams from my radio (HQCT,...) to Destinator for routecalculation then I should do this not too public...
or if I want to get informed (while I am listening to my media and I am currently in media not in nav-mode) if I pass certain "POI's" ("free" photos!

) than It could be added to Navit ...
Means: Destinator and MapPoints SDK is crap.
What about stopping to buy Destinator and donating 30 Bucks to the Navit team ?
