Summary: THE NAVIGON 5100 WAS A RECONDITIONED UNIT. WHEN RECEIVED, AFTER CHARGING, WORKED FOR A FEW HOURS JUST GREAT & WE LOVED IT. BUT, UPON A FOUR HOUR TRIP FROM MA. TO NY, IT STOPPED WORKING AS WE GOT INTO NY. THAT WAS PRETTY UPSETTING OF COURSE, AS WE DON'T KNOW NY. ON THE TRIP HOME, IT FROZE AGAIN. WE SHIPPED IT BACK AND WERE REIMBURSED TOTALLY. THE COMPANY WAS GREAT ABOUT THAT. WE TRULY FEEL THAT BUYING A RECONDITIONED UNIT WAS NOT THE WAY TO GO. BUY NEW INSTEAD.
Summary: ...... if you need ANY kind of support for this product, do not even think that you will speak to a human being. they want you to go to their website and "someone will get back to you within 48 hours!" FORTYEIGHT HOURS? i am so upset with navigon that i will tell EVERYONE that I know NOT to even think about purchasing one of their products!
Summary: I bought my Navigon a little over a year ago. Its performance has been mixed, in line with much of the reviews here. However, I can now unequivocally state that you should NOT buy this product. Navigon has abruptly left the North American market, leaving customers, even those who purchased a device and map updates within the year, almost completely without support. If you buy one of these, you're buying a dead device with no hope of updates.
Summary: This unit worked fine - my new TomTom 1 (the cheapest) is easier to use but lacks the traffic and text-to-speech - until it broke. I had been using it for 6 months, placed it on the floor, and it never turned on again. Thinking it may just be a defective model, I have refrained from writing a review until I gave Navigon the opportunity to fix the problem.
Summary: This GPS is horrible. The GPS told me to make a U-turn in the middle of the highway. It also takes it forever to get good reception. On top of all this Navigon customer support sucks. You can only receive support through email. This is alright if you have technical questions, however if you need the GPS or a part replaced Navigon will reply they cannot do this. Because they do not have the resources to know the inventory in North America.
Summary: I bought the Navigon 5100 for the lifetime traffic feature. It works, up to a point, but the antenna is very cumbersome and it is absolutely required as there is no traffic reception in my area without it. Many others mentioned the weak speaker volume, and it is indeed a problem. My car is a convertible, and it is difficult to hear the speaker at all on the highway. The biggest problem, however, was the touch screen.
