Question about Alpine CDM-7854
The most common reason you would loose the presets is if the yellow wire from the radio is not connected to a constant voltage source. If it is connected to a source that only gets voltage when the key is turned on, you get the problem you are having. That yellow wire is for memory.
If the yellow wire is getting it's constant voltage source, then you have an internal electrical problem that would need troubleshooting by a professional technician. The battery being disconnected and then reconnected should not cause this problem by itself, but it is possible that the radio may have gotten a surge of voltage somehow and caused a failure of some electronic component or maybe caused a circuit trace to burn up.
Since the radio works and the only problem is the memory is not working wold indicate that the yellow wire is connected to the wrong type of voltage source. It is possible that it may be an internal problem of the radio, but the more likely thing is the yellow wire.
