To Texas's observation I can add:
When I go visit my mother, I never use my gps, for obvious reasons ;) Since a few weeks I must make a detour for the last bit because of road works.
Reading Texas's post I downloaded Sygic and set up the destination, my mothers house. Sygics makes the detour !! Tomorrow live testing.
I set up the route on NextGen and NextGen isn't aware at all. I find that somehow dangerous as a few screens taps must be made to block the route (and later on to unblock?), meaning one has to do that in a safe way and best stop, which isn't always possible.
BTW, The full Europe Sygic package including life time updates is now 19,99 euros (offer valuable till the 15th), normal price 79,99 euros. Just saying.
If only NNG could make such offer and update maps as often as Sygic, that would not only be a miracle, but a commercial success as well.
