It is probably safest to disconnect the negative terminal on the battery before you do the swap. If you have navigation, make sure that the little red LED on the nav computer turns off before you disconnect the battery. (This usually takes about a minute or so.) The exchange will not require any recoding.

All that said, I remove my TV module, nav computer, and DSP amp all the time without disconnecting power. Officially, that is probably a little reckless, but I like to tinker.
