Leaving valuables in your vehicle in plain sight is an invitation to theft.

Thieves don't need much of a reason to break in to your vehicle and

if they see that there's something of value worth stealing they will not hesitate to act.  

To avoid this don't leave any sign that there might be valuables out of sight in your vehicle.

Such has docking stations, phone chargers, or connector cables. Leave nothing in plain sight

that might make your vehicle worth investigating by a thief; not even loose coins or a CD.
