Will Nokia sue us for offering their map format?.. If yes, we certainly break record....
No, it same case as create garmin map format using third party compiler (cgpsmap).
usually, in software EULA we able to create generic "DATA" format using by third party program..
this case similar with using another third party editor such as open source editor to create word or excel data format.
but it's not same case with using illegal copied of "crack" program such as using the crack of garminXT.. or using illegal copied of ms office.
and we break the rule if modified garmin officially map to be free maps.. or vice versa (reverse engineering free map format tobe "non-free" map such as SLA/NT map)
