Cheers,
Wouldn't have noticed about the aerial due to having broken it....on the list for replacement 
Done yours yet?
Those CD changers are a right PIA, mine was driving me mad!
at the end, it would intermittantly eject the mag or not, lots of button jabbing needed.
When playing, loads of skipping, bit of interference, would only really play about the 1st few songs on a CD.
Very happy to be rid of it.
Does sounds like you have had very bad luck with yours 
Yeah, my car's not giving me the best impression of Omega ownership to be honest. Been thinking about getting rid but that won't be a bit yet.
It's the gearbox and LPG problems that are really doing my head in. Everything else is niggly.
I got the replacement aerial cable delivered today from a guy on ebay, plus a few other odds and sods. The radio reception was brilliant until I damaged the cable. Suppose it's my own fault really.
My CD changer has similar symptoms to yours then. Sometimes it will stop playing about halfway through a CD and take ages to start playing when I turn the stereo on. The Pioneer will be going back in when I get the loom sorted for it.
