I have just completed a trip from Townsville QLD Australia to Newcastle NSW Australia, a distance of 1800 Klms. On many occasions during the trip my TomTom was not accurate with regards to the posted speed limits (disregarding temporary roadworks). Also many times it lost its way due to dual carriageways and road improvements that are being constructed . Some of these road improvements have been in place for at least 2 years but TOM TOM has the old roads as its guideline and so the route just disappears.
The highway I am talking about is the national route 1 for the East coast of Australia ( A1 and M1 )m which runs many thousands of Klms. I am at a loss as to how to bring this to the notice of Tom Tom as I consider this to be a major problem for anyone travelling Australia's National Highway.
Hopefully someone in power reads this .
