Music Box

Does anyone know if your battery dies or is replaced, do you loose all the stored music in the Music Box?

no idea bout the pathfinder storage, but logically its definitely no.

whether its flash memory or magnetic, both dont lose data with no power.

Thanks mar1, I am looking at upgrading the battery and do not want to lose everything I have loaded into the drive (1500+ songs).

If you want to play it safe, there is a tool that connects to a 9V battery and plugs into the cigarette lighter or power socket to privide enough power to retain the memory settings. Also, if you disconnect the battery, you may have to relearn the steering wheel position sensor and idle air volume.

+ radio stations. thats the worst thing ever trying to remember your radio stations.

Thanks for your response SMJ. Do you have any info on the tool? Also not sure what the steering wheel position sensor is and the idle air volume. Would the truck learn this automatically after driving a bit or are these something that need to be manually reset?

Your are right mar1, but that will be the kids problem, all the radio stations are set to their favourites. The Music box is mine.

Here's a link to a memory saver available for $10 from Amazon.com. Never use one of these when working on/removing/replacing air bag system componants!:

If you disconnect the battery with the wheels straight ahead, you may be okay with the steering wheel position sensor. At first, the VDC and SLIP lights will illluminate but as you take it for a drive, they may turn off. If they stay on, you wheel have to erase the stored codes and reset the steering position sensor. I believe you need a capable scantool to do this. If the idle air volume memory is lost and not relearned, you could experience high or low idle and/or stalling. Over time it will learn this, but how long one can't say. There is a manual method to relearn it and you can probably find it somewhere on the forum; it's a bit of a pain without a scantool that can perform this function.

Thanks again SMJ, you're like a living, breathing service manual!

Yeah, but I'm getting old and lately some of my pages are starting to fall out!
