The Odys Tablet Connect accepts with me in the car for a long time the function of a navigation device, MP3 player, telephone with speakerphone and more. Even texting and surfing the Internet is pretty good, if you stand in a parking lot (anything else would be stupid, costs points in Flensburg and vulnerable people!) The resolution of the screen is relatively good with 1024 x 600, but of course not "the Burner" , The brightness of the screen is acceptable, as long as sunlight is incident on the screen (as in many other, commercial navigation systems, moreover,) directly. The volume (music phone) is sufficient for the operation in the interior of a car is not definitely out (too quiet). For this reason, I have connected the headphone jack of your tablet device to the AUX input of my car stereo via a jack plug cable. Who has not so radio, but has a USB input on the radio, can accomplish the same with an "Audio Adapter Micro USB to 3,5mm jack plug". Now the voice of the lady (optional Lord) is heard loud and clear from the Navi and the music of the MX player can can hear genuine. As Navi software I use the program of company Sygic one with maps of Germany, Austria and Switzerland. An inexpensive and good navigation, which is also able to include traffic reports in the navigation. The Odys Connect tablet meets all my requirements, the GPS system works very well and can not be said that the device for these tasks would be too slow. Here and there a little jerky sometimes when you surf the Internet, but for a "car computer" enough performance anyway. Beautiful machine at a very interesting price!
