Generally I have my iPod/iPhone hooked up 99% of the time and don't notice that i need to hit the Aux button as it's already on there. Might have to check in with GCCS and see if they can play around again with mine, so it will change to the Camera no matter what input (Radio/CD/Nav) the system is on.

I think for you to avoid the AUX button, you need to install a relay which is pretty pricey. Andrew from GCCS imports them from the USA and not sure if he has stock anymore.
He quoted me initially a few options:
1. $750 for Alpine camera with use of AUX button
2. $600 for a cheap camera with use of AUX button
3. $1500 for Alpine camera with relay that engages when car is in Reverse
4. $1350 for cheap camera with relay that engages when car is in Reverse
I ended up taking Option 3.
As Mr BMW said, each to their own.
