Hi all,
I’ve got an R Series Scania which I’ve inherited. Whenever I’m on a phone call the other person is complaining of bad interference, sounds like a constant whistle.
The microphone has been swapped with another truck however it’s not made any difference to the noise.
When the mic is moved on the seat it stops the noise for a short second.
When the night heater is turned on it sounds like a Dalek is speaking.
Has anyone else ever experienced the same thing and know what it is?
Thanks
Ben
