Service [Q] Track device with Timur's USB ROM

Hi

I use Timur's USB ROM in the dash of my car. I use the same Google account on my Nexus 7 (with Timur's USB ROM) as on my Nexus 5. I can track my Nexus 7, with Android Device Manager while it's awake. Is there any way to track it with GPS while the ROM is down in "deep sleep".

When I turn of my car the pad is going down in "deep sleep" and Flight Mode is enabled if I use an OTG Y cable. From here I can't track my device. Want this to work so I can track my car if it's stolen from me.

Any suggestions?

Thanks in advance.
