It may not be a big deal in not having Total traffic installed. TTN has restrictions, depending on the coverage. In my neck of the woods, TTN only gets info M-F, but not on weekends. I have Navteq as well and I've tried everything under the sun to remove TTN cuz Navteq traffic is better (for me) but I am now stuck with TTN as it gas a stronger signal. Remember, once the code is entered, you cant remove it. I have the 750 and I havent checked to see if there is a new traffic firmware update but if there is, I wont updated or maybe I will, if it kills TTN.
