Any way to add red light + speed cameras?

I just bought a genuine Australian map for a E46 M3 (the HIGH map for the MKIV system). Is there any way to hack it so I can add red light and speed camera POIs? (As a side thought, maybe even Caltex petrol stations)



Anyone done this before? Previously I had bought a 2013 map with all this in it but I t=don't think the chap I bought it off sells anything any more.
