I'm wanting to find out if there is anything you can add on for Road Train routes? I had a look on the Tom Tom site, I couldnt find anything.

Anyone know if there is something for any brand or sat nav? Partner has a dumb shit 2 up partner and he keeps getting lost in random places not so fun in a big truck to do a u turn!

AFAIK, Navman, TomTom and Garmin GPSs you seen in shops are aimed at consumer markets. However, there are a few out there designed for trucks, these also include features like height of vehicles so if there's a low bridge it doesn't go that way.

Only thing is, the name of the makers who do those escape me at the moment. Maybe Google?
