WTF is with that? They did the same thing when they broke into my Subaru. They took the stereo (that sucked, anyway), left the remote for it, and popped the trunk from the driver's seat. I didn't discover that my emergency bag was gone until I finally drove off and discovered the trunk unlatched. Lost a map book, blanket, first aid kit, extinguisher, tow strap, and jumper cables.
Gawd, that sucked. I am soo sorry. I have literal nightmares about someone stealing my VX. That might be why it doesn't get out of the garage much anymore.
