Had it less a day before returning it.

The Navigon 7100 looks good but is much larger than other i=units of same screen size.

The user interface is not at all intuitive and trying to input info on the touch screen is frustrating - requiring multiple taps before entry is accepted. This is true using your finger or the stylus. It is not that you touch the wrong part of the screen because you see the button indent when you touch it but the unit does not respond.

Also, the flow of info is not intuitive - it is like calling a help line and getting someone in India, the person speaks English but a different kind of English from America so you have a had time following his or her thought process.

It becomes quickly obvious the programming was not done hear.

Another big negative is that you can not enter an address using an intersection.

I was just terribly disappointed.
