I use Multimap nutty

I would use the voice instructions nutty. Has to be a lot safer than my normal navigators i.e. Wife and daughters.

Last year in Holland, they almost managed to get us written off becuase of their poor navigating skills.

Plus it took an hour in Bruges to find our hotel (should have only took 5 minutes), becuase of their inability to be able to tell the difference between North, South East West, as well as looking ahead and giving clear instructions from a well designed set of instructions.

Plus sending us back to Ghent from Antwerp, when we need to go North to Holland

Oh yes there are lots of good reasons to have a Sat Nav :-)
