Right, it only happens a few seconds after I've started the engine BUT only when the stereo is on. If the radio's switched off, then no noise - ever.

The noise is one loud beep, then stereo goes silent (but doesn't switch off or anything), then after another second or 2, there's a loud 'crack' noise (very similar to a stone hitting the windscreen, or something), then the stereo volume returns.

There's no warning lights, everything seems fine. It's done it since I've had the car - a 1999 TD5 ES auto - about a 6 weeks or so.

Any ideas then?

hands free kit

have you got bluetooth on your stereo? as my focus with factory handsfree used to do something similar

Really? You might have something, I removed the majority of an existing hands free kit when I replaced the grotty after market stereo when I first got the car.....why would it make that kind of noise do you think?

If it is that though, at least it's nothing serious!

No...just a standard, L/R single CD player - but as above, it had a hands free kit in it when I got it, but I removed most of it when I changed stereos......thing is, I'm sure I unplugged it completely from the stereo loom - maybe I need to have another look!
