I have been less than thrilled with nav systems to date. My previous MB S430's nav never had any of the golf courses in it that I was looking to find. In addition, I have this feeling that car based nav systems will be really dated in 3 - 5 years given the huge progress in the handset industry.
Now comes a WSJ story about some funny experiences with Nav.
So, I hope I am happy missing out on the other tech goodies...cause probably not getting ZTP...
