Do you know your HTC Sensation comes with Premium Navigation? When you purchase you Sensation, you are given a voucher code inside your box.
Then from your phone, go to 'Location' app and then enter your voucher code. You will then be able to use the premium navigation for free.
However, the premium navigation comes with voice navigation but only for a 30-Days trial. After that, you will still be able to use the premium navigation but without voice.
Thus, if you are looking for voice navigation, you might want to consider other Navigation app but if you are fine without the voice (just like me) then having free premium navigation is good enough.
Update: Premium Navigation is free for life once you've entered the Voucher Code.
By the way, if you are using HTC Desire HD, you get this premium navigation for free as well. And the best part is that you won't even need to enter the voucher code. Just go to your 'Location' app and that's it.
Update: Other HTC Phone like Desire HD only comes with 30-Day trial unless you have the voucher code.
