My friends GPS was stolen from his car a while back, but I remember it having many roads that tomtom had as blank (around the country side).
I don't know where his map was sourced from, but clearly is a better source than Tomtom, which I believe (don't know) but believe is extremely out-dated.
For example, I tried to go to the city centre of, I think it was Pinheiros, and it wanted me to drive through a concrete barrier on a highway into a park.
The hotel we stayed at in Jardins, Sao Paulo, was showing the wrong direction. We could find our way home to our in-laws because Tremembe wasn't a city in the map.
This was all in DAY 1.
Another day, from Tremembe to Embu, put us in a forever circular route, because it didn't know the exit, and took us into Alphaville, way off track.
EVERYTIME, I take it through the city, it wants to go the wrong way. One time, I was forced to take a strange road because tomtom backed me into a non-through way, which it wanted to use, and I had to drive into a notorious drug neighbourhood called CRACK-O-LANDIA. My wife was screaming with fear. Another one of tomtom's daily antics that put our lives in danger.
Again, using my memory, in Santana, it wanted me turn right, and as I started to, my wife screamed again, as I strarted to drive the wrong way up a one way street...AGAIN. This something is extraordinary frequency.
I can only assume these tomtom maps are so old. Because some of the paths they want me to take, have clearly not been used for a long, long time. (the concrete barreir in Pinheiros was old, broken contrete), this wasn't a new change. The Park had been there for decades.
Again, I can make a hilarious video. All I have to do, is get in the car and set the GPS to ANYWHERE and then just film it.
