NOTE: Some systems store data in memory that is lost when the battery is disconnected. Do the following steps before disconnecting the battery.
1. Make sure you have the anti-theft code(s) for the audio and/or the navigation system (if equipped).
2. For some models or if you're replacing the audio unit, it maybe necessary to write down the audio presets (AM and FM), and the XM audio presets
(if equipped), because the audio unit does not retain the presets after the battery is disconnected.
