VY Blaupunkt radio problems

[Crawl]

Got a bit of a problem with the Blaupunkt radio/CD player in my VY Commodore. What happens is this :-

- I go out to the shed in the morning and find that the clock has stopped during the night. The "security coded" light isn't blinking. No response at all to any buttons on the radio unit or steering wheel controls.
- drive to work, park car outside.
- come back to car in the afternoon to usually (not always) find the clock now working, security light flashing. Radio now working .
- next day starts all over again with clock stopped and radio not working again.

Asked Holden dealer to have a look at last scheduled service, of course the radio was working ok. They said they took it out for 30 mins and put back in and couldn't see anything wrong.

Should I just replace the radio unit or anything else I should check?

thanks

my vz has a similar problem, except the radio works only on the steering wheel controls, what did you end doing?
