The Mégane II Owners' Club

I fitted this radio: https://www.a-sure.com.hk/products/2-Din ... 836-1.html

When I turn the ignition off it remembers the time but forgets all my radio stations and settings, what cable is the live feed?

The yellow wire is the 12V line connected directly to the battery to provide constant power for memory when off.
The red is the ACC power and only runs when the ignition is turned on.
