Sneeks had earlier enlightened me about the limitations of using multiple waypoints with Garmin, so have been taking a much closer look at the Tom Tom GO 910. My journeys tend to be cross-country and here I'm talking the length and breadth of France and adjoining countries, so I thought I'd like the benefit of having an integrated mp3 player, hence why I've now turned my attention to this particular model. Despite reading the pdf manual I cannot establish whether the mp3 player can be used at the same time as the TT in navigation mode, ie, will the mp3 player's sound turn off/go quiet when a navigation instruction is announced. Maybe it's either one or the other - can anyone enlighten me please? Hope you're all having a great weekend!
