The unit will have 2 fuses, or at least a second power supply that is generally connected to
continuous power, best bet is straight from the +ve
batt terminal. If this power supply has been disconnected or has a blown fuse, then you will also loose memory functions from you radio.
- Check first under the bonnet for a memory backup fuse holder that has generally less than 1 amp fuse,
- no luck, then about the rear of your fuse box for a fuse holder,
- or worst, behind the unit up under the dash. The wire from the back of the stereo on Sonys is generally the RED one for memory backup
restoring this power supply to your stereo will then allow for all your presets to be retained in memory
Good luck, happy to talk to you more about the problem, a "FixYa" rating will help my profile
