I had same problem Radio turning itself on when car not in use. Went to local garage they referred me to local Vauxhall Dealer who advised to put in a CD and leave it in. You can still listen to the radio but just before you get out of the car slide the CD back in fully. It works.....

I have exactly the same problem and have a 2004 Astra. From looking at other forums there definitely seems to be a problem with these radios, especially the CD30 models. Vauxhall will not pay for a replacement outside of it's warranty and as mine is 6 years old, it doesn't have one! The cost of a replacement has been quoted as ranging from between £190 to £350.
There are a few suggestions from others with the same problem:
1) Turn the radio off manually BEFORE you turn off the ignition. I have tried this for the past couple of days and so far so good.
2) Keep a CD in there at all times. This doesn't appear to work for me as it just plays the CD instead, however that said the problem has got a lot worse since I took a CD out about 2 weeks ago. Before then the radio would only come on when I unlocked the car, however on Monday the battery was completely drained and the radio has taken to randomly turning on in the middle of the night. So I may try this too just to be on the safe side.

I have an auto electrician contacting an engineer he knows at Vauxhall, so if I get anymore news, I'll keep you posted.

so does mine (2004 Astra) think it's an inherent fault on these models with the radio itself, Vauxhall replaced some under warranty but if out of warranty, will cost you to fix ie replace whole unit
