How do I get back my Navigation to the web page

Go to the Sygic web page and ask that question.

Some programs that you can install like to steal your Home Page. Also there are some Malware and Virus's that will do the same.

Try: Tools, Internet Options, General (Tab) - "use current" (if you are on Yahoo.com)

If that doesn't work try: Tools, Internet Options, Advanced - "Reset"

That should get you back to where you want to be.

Try switching to a better browser like Google Chome or Firefox. If it persists you are having connection problems with your router.

The Firefox "menu bar" includes dropdown menus for various tasks (including "File", "Edit", etc.). If the menu bar does not display, press the "Alt" key (if you are using Windows). That will restore the menu bar temporarily. To restore it permanently, go to the menu bar and select:
View > Toolbars > Menu bar

The Firefox "navigation toolbar" includes the "back", "forward", "reload" buttons, and the address bar (where you type a web address). If the navigation bar does not display, go to the menu bar and select:
View > Toolabars > Navigation toolbar

See screenshot:

Open FireFox.
Press and release the ALT key on your keyboard.
Does the "File Edit View ..." menu show up?
If so, use the mouse to re-enable the toolbars.

I am having a simular problem, but it seems it is with ie 8. As long as I use ie 7 or firefox, I don't have the problem. You might try going to tools and the options and web tab and then make sure to take the check mark out of the "rely on VML for faster graphics downloading" and take the check out of "allow PNG as a graphics format to improve graphics quality"

From Microsoft: "you may experience a problem when you visit some Web pages that are in different Internet Explorer security zones. When the problem occurs, you receive a message that resembles the following: Navigation to the webpage was canceled
This problem occurs if the navigation causes Protected Mode settings to change from On to Off. You can determine which Internet Explorer security zone a Web page is in by looking at the status bar at the bottom of the Internet Explorer 7 window.
This problem occurs because Internet Explorer 7 switches Protected Mode settings when certain Web pages are configured in the Trusted Sites area of the Security tab of the Internet Options dialog box. By default, Protected Mode is set to Off for Web sites that are configured in the Trusted Sites area"

I advice you 2 things:
1. check your internet connection.
2. In your internet explorer look for Tools, open it, click on connections tab. Then click LAN settings tab. Then check automatically detect settings. And remove check from proxy server settings.
This should work, otherwise look for help and find somebody who knows about unconfiguring group policy settings for your computer.

 They don't offer a whole lot of info. To see the manual for this go to their web page and then click on "navigation" under the "mobile video" tab. You can check for map updates under the "download" tab, but don't expect to see any.
