Hi
Can anyone tell what Destinator 2 uses for a map datum for UK mapping?
My GPS cards uses WGS84 which I guess is pretty usual, however I have noticed that fairly consistently, if I pass a motorway slip road so that it is to the north of the motorway, Destinator thinks I have taken the slip road.
Could this be due to Destinator using a different map datum which means that it always thinks I'm a few 10s of meters further north than I am?
Cheers
Dave

Street navigation program don't actually know anything about datums (dati? data?) , and by default they use WGS84. You deviation may simply be due to bad surveying data.
