Optimization option: A second 12V socket would be the icing on the cake. -D
Side note for design:
During the TomTom Ladeadapter really should easily fit into any 12V vehicle power socket, is some extra space to the 12 V vehicle power socket from emergencies around the laterally flanged USB ports. Depth is the 12V connector of the vehicle and thus possibly surrounded by the material of the instrument, as the charger may not be insert deep enough. But that is rather stupidity of vehicle manufacturers as a liability of TomTom.
Tip for connection of music players:
When music playback devices that are powered from the electrical system of a vehicle with power, noise may occur, for example, by the ignition of the engine. As a countermeasure usually suppression filters are connected vehicle side before the 12V socket, however, may not work with any 12V outputs, as long as the car offers more. So in my car (Toyota Corolla Verso) the front 12V socket is suppressed (cigarette lighter), the additional 12V socket for the (1) rear row of seats, however, is not suppressed.
