Replying to So my Car stereo got stolen today

I went into the mall to check out some stuff with my friends, and i come out and it looks like my dash was ripped apart, yea i know your gonna say i should have locked my doors, well they were, i think the guy jimmied the lock. Is there anything i can do or should i take the loss and just buy new stuff. Really bummed me out, luckily he didnt steal my skis, tomorrow im gonna double check to make sure everything is in there
