Ok so here's the deal, to make Telenav auto rotate you must make these regedits:
Code:
[HKEY_CURRENT_USER\Software\HTC\HTCSENSOR\GSensor]
"AutoRotation"=dword:00000001
Then in this key:
Code:
[HKEY_CURRENT_USER\Software\HTC\HTCSENSOR\GSensor\ModuleName]
add this line:
Code:
"SprintNavigation"="\\Windows\\SprintNav.exe"
Now, the tricky part is the next and last edit. We need to add the telenav entry to this key:
Code:
[HKEY_CURRENT_USER\Software\HTC\HTCSENSOR\GSensor\WhiteList]
One must know the main class of the app that one wants to auto rotate. I don't know the Telenav main class and a google search for it didn't bring up any results. If you really want to get it done, I think you'll have to flash a ROM that has Telenav autorotating and look in that registry at the last string I mentioned and see what they have as the "main class" for telenav. Without setting that main class entry, it won't work. Sorry that I don't have an instant answer for you.
Edit: I found out the Telenav main class name:
