I did get TomTom V5 to work on my N82...The new TomTom's (920 I know of) run on Linux so one would think it that maybe the newer versions might....not a programmer so I can not help there...

Off topic, when I lease a car it is a lot less than buying AND I can purchase it after the lease term..NOT SO with Nokia maps....Nokia maps are the same price as the TomTom software which I would own..not a good business model.... which is why I am not using their software, google maps with traffic is free....

BTW, the GPS on the N82 is very fast whereas the N810 works only outside and s-l-o-w....
