That has to be a fairly large drain to kill the battery in 24 hours. Disconnect the positive battery cable and put a meter set to amps between the cable clamp and battery positive post. Have somebody start pulling fuses one at a time until the amperage goes to zero. Start looking at what is on that circuit to find the culprit.

Pulling fuses is a BAD way to diagnose drains !!...by pulling fuses you start to possibly wake up modules and skew your readings.

When I was dealing with a similar situation (08 Base w/ Nav), it was my OEM Bose Nav head unit that wouldn't stop trying to cycle and/or spin up a CD even after the car went to "sleep." It would run and run and run....
I lived with it and pulled the radio fuse for......years....LOL (under the passenger side footwell carpet) any time I parked it for more than a couple hours until i finally bit the bullet. Changing the head unit solved the problem. Sound is way better now too so win-win.
