Stereo interference

[Jim300186]

Hi I have a 992 4s, when driving I’m getting really annoying feedback through the stereo every couple of minutes. The opc I use have said Porsche uk have said this is ok! But surely it can’t be! Anyone else have this problem?

Regardless of the input the noise stays the same and stays at the same volume. So if you turn the stereo up you can drown it out, but this has led to a lot of 1st, 2nd gear limiters as I drive in manual a lot lol. I have the Bose sound system fitted to it. I have turned the phone to airplane mode and it made no difference. Dealer has it at the minute there saying it is to do with the tracker system, which I don’t use. There saying the car is looking for the tracker card! Could someone do me a favour, and start there car without the tracker card present and see if this causes a noise? Really doing my head in now! Have said if this is a standard 911 thing i will be cancelling my turbo order!!
