Default Change Battery - Keep Settings

I have a 2005 Camry XLE 4 cyl. and I'd like to put in a new battery. I read
somewhere that it's possible maintain the radio/garage door opener settings
by connecting a small 9V battery to the PCM while the main battery is being
switched out.

My question is, if this is so, how is it done and where is the Powertrain
Control Module? Or is it just not worth the bother/risk?

Thanks, Rob
