Started up the car this morning and the radio came on as usual (I
usually have it defaulting to 'on'); however, the normal music and
chat was accompanied by a high-pitched 'beep' about once very
second. I've switched on and off, disabled all the radio's clever
functions, but can't get rid of the beeping. What on earth is it?
Help please!

The radio has a security feature whereby you need to enter a PIN if
the power is interrupted; however (a) it wasn't interrupted; (b)
it goes into a mute status with a PIN prompt on the display; mine
didn't do either. I just mention this in case anyone thinks that's
what the problem is.

I am assuming this is the Blaupunkt G5 unit. How long have you left
it on for whilst it is beeping? It normally does this for about 5 -
10 minutes and then asks for the code. Once the code is entered it
will be fine.

Bingo! Sorted; thanks very much.

Do you know what would have prompted this behaviour? I'm sure that in
the past if ever I've disconnected the power, the unit switched on
silently, asking for the code immediately.
