DON'T leave it in the car under ANY circumstances. There is no way you can replace this unit now, and it's highly unlikely you'll see it's like again. Break ins (to order) through garages, static locks, and into cars, are not unknown, especially if it's observed you regularly leave it in the car.

There is currently a slow, but definite rise in the number of thefts of empegs/Riocars - don't get added to the list
