I am in need of a user manual for a NAVONE 3000 and would like to upgrade the maps on line

1- You need to install cobras update software which is available at their website.
2- Seem to remember that you had to register the unit with cobra otherwise the software would never work. (Might be in error on that though)

Once that is done it should update with no problem.

which device ?

Cobra NavOne 3000

Go to the Cobra website (see Resources) and click on "FAQ" at the top of the page.

Use the drop-down menus to select "Nav One 2750-2950-3000-3080" and "Software Updates." Click "Submit."

Click "How do I get and load software updates?" Click the bold "HERE" link.

Scroll down and click "Nav One 3000/3080."

Click on the latest update link to download the update to the computer.

Connect the NavOne's power but do not turn it on. Connect a USB cable to the computer, and connect the other end to the GPS.

The GPS device's LEDs light up, indicating a connection.

Double-click on the update file you have downloaded.

Click "Next" until the update begins.

When you are notified of completion, close the update

hope this helps

unfortunately, if you locked you unit and dont remember the passcode, the unit has to be sent in to cobra because they are the only ones that can unlock it. Its an anti theft measure. Their contact number is 1-773-889-3087.

You can purchase map updates via Cobra's website

Hi Raymond,

You can download a free copy of your owner's manual on this page:
gps-devices/user-guides/">http://www.navman.com.au/car-gps-devices/user-guides/

If you need to update your maps, check this site for downloading instructions and downloadable ISO files for installing the more current maps. They may or may not be free, depending on your previous map purchases. They also sell the upgrade software, but its a little pricey. They are located in Australia.

I hope this gives you the info you need. Let me know if I can be of further assistance. Thanks.

I have cobra Navone 3000 Gps. I need to update maps on it. Could somene tell me where to get free map download for it please?

The only thing I can suggest is to shut it off and reboot. I have experienced an occassional problem like that and seems to be related to calculations for some areas. There is an area in OK where mine will lockup everytime I go thru there. Try downloading the update from the Cobra site. It is a 2005 update.

Hope this helps.

Unit does not have a demo mode that I can find or have ever seen and I have been using mine for over 4 years.

Turn it off and reboot.
