chosen for its superior power to the mean has the product meets that expectation and functions are attractive and functional, however the problem arises for example music by blutooth which is a little anything with the slightest movement of the mobile connected, rolling the car radio sometimes cuts or blocks on his car and continues even extinct (requiring the outright disconnection of the car radio) sometimes by rolling the device will switch off and on again by delivering music and settings when the car started (problem with the internal memory ???)
