Hi problem with radio, whenever I drive pass Heathrow airport from jct 12 to jct 14 my radio turns of itself twice and then comes back on, but it doesn’t happen if I’m driving back from Heathrow anti clockwise. Also happens near where I live on countryside road.... I told Mercedes and they said it might be to do with the cameras near Heathrow, has anyone else had same problem with their car? It’s 2017 e class
