A new CMAP is how much? I think my last upgrade was $130 and that's the whole of Australia.
My old chip is sitting around, it has QLD, NSW, and maybe Vic. If it works for you, a carton or a nice bottle of rum will suffice . I reckon you should get a new map, though, as things do change.
Will be back in Brisbane on Thursday if you want to try it out.
Cheers,
Tim
