Live Search by Microsoft and Spring Nav the way to go for Sprint users?

[WhiteWidow]

I just flashed a cooked ROM (MERDIN'S) on my Sprint Touch pro and love it but it took away Sprint Nav and Live Search by Microsoft ( I think that what its called when you use speech to search for a location and it uses the the nav to direct you there). i found the .cab for the Sprint NAV but cant find the live search .cab anyone know where this is?

Also is this the best way to go to for Sprint users? Or is there a 3rd party software that does the NAV and search better? I want to be able to find lovcations with out entering it manualy and get Traffic updates.

Thanks for any Help.
