There is a known issue with torque and the MX sleeping. If you checked the box in torque to put the mx to sleep it actually can keep the mx awake. I was told to uncheck this box then hold down the button on the mx until the led's start scanning. This puts the mx back to its stock setup and it should sleep properly. After you're away from the vehicle for a couple hours look at the mx (if you can) before opening the door or unlocking the door. If the green light is on (or blinking?) its not sleeping. Anything that causes a battery voltage dip (parking light flash, dome light, door locks) will wake the mx up. The mx WILL deeply discharge your battery all on its own if its not turning off. It's current draw by itself taking no readings is pretty high, ask me how I know
You should root your nexus so you can quit torque, turn off the radios, and sleep the device when the ignition is turned off. Then when you turn the ignition on it will wake up the nexus, clear the keyguard, turn on the radios, launch torque, and do what ever else you want.
