The Navi is really top. I've been using it since about 2 weeks with my road bike tours. Routing works perfectly, has stable GPS reception and is really easy to use and understand. I agree to all the previous positive reviews to be happy. But there is a crucial drawback for me. The readability of the display is actually even worse than I could imagine by the anyway very many negative opinions expressed at all. Even changing to another card color helps only very limited there. It's not that you can only read in low light conditions poor, even in low light conditions you have to look very closely. Yes, I have the brightness set to very bright and it has brought to nothing. Another and really well last disadvantage I see is the USB cable. So to make a cable length borders on complete inability. What shoud that? The cable is just 40 cm long. With a practical mindset that has nothing to do. Even more what with cost savings. Too bad, otherwise I would probably still be awarded the 4th star.
