Will Battery Change Erase Navigation Saved Items ?

[Netlander]

Hi All,

I just got 2003 Lexus ES 300 last month, with Navigation System. It's very cool an I think I fell in love my car during valentine

While adding new SAVED addresses and mark items into my Navigation, I wonder if all these items will still be "permanently" save even with battery change or if I accidently drained all my car battery power?

Thanks in advance. I'm still learning all the nice cool feature the car. It's very impressive :)
