Hi CT,
I have a question to that end...
My Scion XD stereo looses all the presets when the battery is removed, but remembers EVERYTHING when I disconnect the power cable (battery power still live) from the unit and remove the head unit and store it, even for a year or more... What's the goings on here?

I cannot understand why this happens, but it does. Did it more than once, and on more than one car.

Thanks!
