My new-to-me 2006 needs a new battery. Any issues with just taking out the old one & putting in the new? I assume I'll loose the radio presets if I just disconnect the battery. Anything else to expect? Can I hook up a trickle charger during the operation to save the settings?

There aren't that many settings, just write them down on some paper before hand?
I'm not even sure if they reset or not, I just replaced my battery and I don't remember having to change anything...
In fact, i have disconnected my battery dozens of times while installing different components of my sound system, and I never remember the radio pre-sets changing back.
But I'm not 100% sure.

"Anything else to expect?"

Your radio to display CODE due to anti theft, you will need those numbers also.

Take you time and clean up the battery tray and area, a lot of debris gets down there.
