TTN definitely works on the TP2... there are multiple threads on it even in this forum... the only issue was getting TTS to work and there is a long thread on that solution... I personally prefer Garmin XT but have used TTN in the past on a TP2... also, the new Bing, if you have not tried it, has turn-by-turn directions now, including TTS, is free, and works reasonably well actually... at least worth a quick look while you're sorting out your TTN issues...
