Matter of fact, it is a 4WD (Toyota RAV4).

Biggerdave, I see in you avatar that you are a TomTom expert. Maybe you know the solution to another of my TomTom issue. TomTom works great but when the "lady in the box" gives me route instructions the music turns off, which is OK, but after the instructions are given the music does not get back on as expected. The head unit just goes silent. To get the music back on, I have to go back in the music app and restart the music. I tried several music players with the same result. I tried different tomtom audio channels and still the same result. Any idea what I can do about this?
