Have the Kruger & Matz KM2003 obtained from Ebay, but find myself compelled to write a review here because of bad experiences. The whole device is actually a sham. On the product photo, it looks as if the device is a DVD-charging. In fact, at the console back in the plastic lining the Silluette a DVD loading imprinted. But behind verbirft to - air. The unit has no optical drive, if well this Wirde indicated on Ebay so. Furthermore, the device has the ability to use a Micro SD card for the navigation - this is not included. Ie no maps - the GPS can not even without this card to activate. The whole device is indicated with a weight of 3.5 kg, which is, however, expected packaging and accessories. The unit itself weighs max. 1 kg. In case a board about is a lot of air. Here you can get actually an oversized radio and a poorly functioning speakerphone. My advice: Stay away!
