TP2 GPS Mapping programs

[0Gravity]

Hi All,
I am totally bummed....I had my TP replaced by a TP2 by Assurian, and I was REALLY excited about the upgrade, but I am now in the process of loading all my tried and true Apps that I am used to using, only to find out that the one I used the most TomTom Navigator, no longer works on the TP2! Am I missing something? I have looked to see if there is an upgraded version but I can't seem to find one? Is the TP2 NOT supported by TTN? If not what would you all suggest as a worthy replacement for TTN, I would like a program that does NOT need the memory card to be swapped everytime I wish to use it!

Thanks,
Mike
