Hey guys,
I have problems with the Sony CDX R3300 radio head unit (or at least I think i do). what is happening is that every time i shut it down or disconnect the head unit from the car, I loose all the settings stored in memory. So radio stations are gone, volume settings are gone, you get the point.
I am thinking its something to do with the battery that keeps this stuff stored. Am I on the money or is it something else? and if its the battery, can i replace it my self?
Thanks,
