When slowing down, my (recent) radio switches off automatically. After a couple of seconds, it turns on again.

Alternator seems to be fine.

Any thoughts why this is happening?

Thanks in advance.

Regards,
Bernd.

Any more clues ??

Loose connection perhaps but would have thought it might do the same on acceleration, sharp turns ??.

Not sure if it is related, but after ignition is on it takes approx. 10 seconds before I can open the roof.

I have a Continental radio. It switches off when power is removed. To switch on, you must press the button. It does not switch on when power is applied.

So, your situation sounds odd. An intermittent power connection would necessitate a press of the button to switch on again.

Certainly, check the connections but I'm inclined to suspect the radio itself.

This assumes, of course, that your radio is similar to mine.

There is switched and permanent power. The radio never looses its presets, so I guess the switched power is being reduced for one reason or another below a certain speed, and only temporarily.
My radio is continental CCD7418UB-OR
