[Q] Remote enabling GPS - Stolen device topic

Hello guys,
The unthinkable has happened, I forgot my phone in a public place...

*Running 5.1.1
*It's rooted
*Its not encrypted so theoretically someone could wipe the device bypassing the lock screen
*I know that no one has wiped it yet because I can remotely install apps via playstore and verify that they have been installed, meaning LTE is still enabled, and it has battery life.
*I have Android Device Manager installed

Here is the kicker, I habitually leave GPS disabled to lengthen battery life. I've remotely installed Cerberus to the phone but I'm not sure if there is any use trying with cerbus if I haven't launched or signed into cerberus on the device itself. I'm wondering if anyone has any ideas on how I can remotely activate my GPS? I'm running out of time before the battery dies or someone wipes the device. I have to either locate it or remotely clear the internal memory.

Thanks for any help guys.
