At the back of the head unit, there are usually two power connections to the car battery live. One is via the ignition, and the other is (usually) a fused connection that connects directly to a relay or fuse that has constant power, even when the car is switched off. This constant power allows your head unit to hold its memory. If the loss of memory is intermittent, it could be a loose cable or corrosion on the fuse.

SOURCE: Memory loss

you need to remove the radio and swap the red wire for the yellow wire and vice versa, they have bullet connectors to allow you to do this, basically the permanent live and the ignition live are the wrong way round.

Hi, my problem is that each time I turn off the ignition I lose all my radio settings (i.e. the station pre-sets). My Sony is a CDX-L400X. I was wondering if there is an internal battery (like a button...


Hi, the problem is likely in the wiring or possibly a burned fuse. There is a separate wire to the radio that is always hot and keeps the station and clock settings while the key is off. If you tell me the car model and year, I may be able to tell you which wire and fuse to check. Was this working originally or has it never worked?

Radio stations fuzzy and not coming in anymore - Sony CDX-GT310

I don't know how to set the preset stations


Sony XPLOD CDX-GT200 CD Player
Radio:
To receive store stations(press); store stations (press & hold). Preset tuning is not possible, however one can store the correct frequency in the memory.

Manual storing:
while receiving the station that you want to store, press and hold a number button(1 to 6) until "MEM" appears. The button number appears in the display. PS: If u try to store another station on the same number, the earlier station will be replaced by the new one............................................sodeep

Do you lose them only after the car is turned off? if so, your 12 volt Costant wire (yellow) is hooked to a switched 12 volt source.
