Hi,
Had exactly the same problem.
Found answer on: http://www.206info.co.uk
which said:
If you are having problems with your headunit, for example when you turn the ignition on and off you lose the settings from your headunit. Or perhaps your unit will not go over a certain volume without cutting off!
Change the RED and YELLOW wires around at the back of your headunit.
A bit more info on this. The Red and Yellow wires supply the Headunit with the following:
Constant low level power - yellow lead - this is direct from battery and stays live even when your car is off, it allows your headunit to have enough power to keep its memory settings
Ignition feed - red lead - When the car is running, the headunit is supplied with more power from ignition to power it for general use.
With many headunits, these two wires dont come set up the right way round for the 206, so your headunit will run off low level power when on, and may cut out when the volume is turned up (as it doesnt have enough power going to it). Also, as the memory feed is coming from ignition, when the car stops running, this feed stops too, and the headunit loses its memory settings. Switching these two wires around fixes the problem. Many new headunits come with connectors that allows you to easily change the wires around.
This should fix the problem!
Good Luck
