My siggy is a sports tourer so it has this extractable boot cover, and I believe it should somehow lock into place when it's fully extended. Mine however retracts by itself and never stays put. It feels as if some notch or hook has broken off. 
How does this work? Anyone got a pic of how the mechanism should look?

I have a 2010 Astra. Recently, the car radio has not been turning on when I start the car. The screen is completely blank, but it does come on after I've been driving a few minutes.

Alongside this, the indicator lights work, but the sound does not work until the radio comes on.

Any idea what this is, and whether it's a common problem? I've had the car for almost six years now, and it's always been very reliable.
