Question about Kenwood DNX7140 Car GPS Receiver

2 Answers

Hi - Navigation screen stays completely blank - ie black. The rest of the functions are fine. When I then display the source selcet screen the navigation icon is red and if I press it I get a picture in the top left corner that shows two rectanglest with arrow from the smaller one to the larger one. Have upgraded the system software from 1.2 to 1.7m and tried to update the Garmin software, but can't because the navigation screent is blank. Hope som eone cam help.

    Thanks - is there any way I can completely re-set the navication software? What do you recommend - should I just take it to a dealer?

First go to the following website:

https://buy.garmin.com/shop/store/downloadsUpdates.jsp?product=010-00752-00

You will download the latest Garmin software from this page. Save this to your computer. Then go to the following website:

http://www.kenwood.ca/Support/Car_Entertainment/Software/Garmin320/

This will give you the rundown on what to do to load the updated software into your Kenwood unit. As you can see from the screenshots you'll be able to do the update even if you cannot see the screen. As noted at the bottom right of the page you may end up having to take the steps 2 or 3 times before the update finally takes. If, after trying 2 or 3 times, you are still having issues you may have to take the unit back to where you purchased it to have them do some warranty work.

My sansa e260's navigation wheel lights up but the screen is blank. what do I do . It may be the battery is completely dead. Bob L.


Your battery is not dead because if it was, then navigation wheel would not be lighting up. Your screen is blank because when you touch the navigation wheel, you probably decrease the brightness of the screen. Turn the wheel counterclockwise, as this will brighten up the screen display. Press the center button when done. Reply back if this solution does not help.

I would recomend looking behind the left access cover in the trunk where the navigation computer is located. Inspect the area for any water intrusion, and if possible check the connections to the navigation computer for water or corrossion. the display colors are generated by the navigation computer via RGB lines. If the nav computer is cutting out, that would explain why a battery reset helps restore the picture.

Turn on camera but the lcd sceen is black


I tried all the solutions offered on the net and none worked except one. It simply said "hit the camera with the palm of your hand" (when it is on) and the screen will return. I thought, well I have nothing to lose and so I hit it on the side and sure enough the LCD is again working !!! Contacted Canon prior to this and they had no idea but suggested I send it in to be repaired at a cose of $163.50 Australian. Pleasant staff they have, but no help in solving what looks like a common problem of Canon cameras. I will have second thoughts purchasing Canon from here on in.
