[talk-au] 'Break in' the list

[Franc Carter]

Yes, I haven't been blown away by the map quality in Australia. I am using
the
latest Sensis maps on a TomTom and there are two errors within 500m of
where I live that result in incorrect directions ;-(

I also found that the sensis maps (or maybe the tomtom ignores) don't know
when a road is un-sealed, which led to a rather unpleasant trip ;-(

cheers
