My cabasse radio keeps turning itself off after about 20/30 minutes.
Is there anything I can do to stop this?
I did not get a handbook when I got the car so any help would be great

If it happens when the ignition is off, it's normal, in order to preserve battery life.
If it happens when the ignition is on, it's not normal.

The power to the radio has two +12V feeds, one permanent, and one switched by the ignition.
If you use a voltmeter, check if the switched feed does receive power when the keycard is inserted.

Thanks
Yes it happens when the ignition is on.
Will have a look.
If it helps the clock doesn't come on unless i switch the radio on.

That tends to be normal behaviour for the clock, unless you drive with the headlights on during daytime, like I do
(something I consider a good habit, when driving a car without dedicated daytime running lights).
