The case itself makes a good impression. However, there is a whole area too small for the TomTom Start 20M (and how to learn from other reviews probably for other devices). So, now, but still a little more detail. "Too small" is relative, so what you bring because under? When the suction cup of the M20 brings you removed the device, the USB charging cable and the foot separately in the Case under. However, not "somehow" but you really have good simple so it goes. Thus, the case is fully utilized. The car charger is brought together with the device not at all under in the case. For the 12V connector is just too big.
