As I said in another post, we have finally acquired a rig - an 11.5 tonne, 8.5m bus. It is dead sexy!
However, on the way home, the GPS and local information from Visitor Centres saw us in a few sticky spots - we need dedicated big rig GPS maps - so probably a new GPS. We currently have a Navman MY65T, which is great for the 4WD, but not the bus (Marriners Lookout at Apollo Bay anyone?!) An image of the road there (which we were told was fine for us, "They get coaches up there all the time!), is attached - we took up almost all the road, and it was all up or down, and windy as Hell, rather scary.
We are also looking for side/rear camera suggestions.
Rosie, not sure about the MY65T but we've recently downloaded a heavy vehicle add-on for our MY85XLT. If available for your unit it could be a sensible option.

Have you checked the Navman website? They may have the big rig maps available, or tell you how to get them. If you have to buy a new GPS, the salesperson shoould be able to set you up with what you need. I vaguely recall mention of certain units for big rigs (that is, not all GPS's provided maps for larger units) when I was looking, but as it wasn't a concern to me I didn't give it a lot of notice; perhaps a discussion with a truckie would be useful.
