I have just discovered that I cannot operate the radio's TA button and switch off the radio to listen to spoken instructions while using the TomTom sat nav. My previous car, a Toyota Avensis allowed me to use the sat nav and TA information cut in when it was broadcast. As I do not want to have the radio playing in the background while following the CX-5's sat nav, i would be grateful to hear if any member knows a way around this.
