I'm having the same issue... What I was told by Sprint after 8 reps and 3 tech support phone calls between today and yesterday is that TeleNav is the preferred version of navigation for the TP2 via the "TeleNav_Sprint_PPC_5.5.18.cab" so as to why the other version "Sprint_Navigation 2_1_40_0.cab" is even available for download was unknown by any sprint tech I talked to, they said that's not even listed on their site for the TP2...

So the one main thing I'm left unknown to is why did I get an email 5 minutes after my resolution phone call to TeleNav for them to reactivate my "expired" account, saying that "Your service is extended to 2010-05-04" so I guess it's one more phone call to TeleNav to explain that email, even though Sprint said disregard it because they sent me a download link to the TeleNav navigation and said that was their version not TeleNav's "although it almost reads the same exact install file"... Oh well, I guess this issue is semi-taken care of minus a few unanswered questions that hopefully we can figure out..

TeleNav's navigation file - TeleNav_Sprint_PPC_5.5.24.cab <~~ what you will find if you look
Sprints navigation file - TeleNav_Sprint_PPC_5.5.18.cab <~~ what the sprint rep sent me
