eheheheheheh
maybe your cousin should learn how to use his Lexus sat nav because you can program camera warnings into the factory system.
When your Mum buys you a car, and you're allowed out on the road on your own, we'll show you how to do it & you can show your cousin.
No not illegal.
Now to answer the question before someone asks it: Why is it on a Navman for $150 but not in a Lexus/BMW/Audi etc?
Its to do with corporate morality by the car companies. If they have it programmed into their cars it is seen as promoting unsafe driving. Just the reason the factory nav system has a disclaimer when you start the car about driving safe etc.
Can you imagine Today Tonight or A Current Affair if some P plater killed someone in his Mum's Lexus & it was proven that the factory system encouraged speeding by warning when to do 160km & when to slow back to 60km. As if to promote it.
The speed cameras are actually in the nav data just not utilised by the system, so I'm told.
Its pretty easy to program camera warnings into the system if you really want them and works really well. Plus you only have to program it once, well worth the time IMO.
The RTA even supply a list of their locations
