Clock [Q] Tasker trigger GPS when maps open (G3 rom)?

I installed Tasker (and Secure Settings latest version, granted root) and want to trigger GPS on (high accuracy location) when open Maps and Camera. Also I want to turn off location when return to home screen.

I tried so many different ways, set up a task when I opened maps, I choose Secure Settings, GPS on, Location services on .. but it never works!

Please if anyone is running on G3 ROM (or even G2 ROM) could shed some light on me for this problem?

Cheers

P/S: running Lamhoang G3 and Dorimanx 6.5.1. If it's possible, please share me your file. Cheers!
