Question about Sony nav-u NV-U70 GPS Receiver

9 Answers

I need to download the updated map data to a Nav U 70

When I connect my Nav U 70 to the computer I get a Connection cancellation notice and the unit will not connect - the computer does not recognize it.
This is the same computer I originally downloaded the full SatNav data from (CD) and the unit worked fine. Sony does not appear to have any technical after sales service engineers. The unit is very nice but I need assistance. thanks

First, You MUST use the AC power adapter when connecting the unit to the computer. But if you are using the AC power and the message still is the same, try the following:

Note:Because each of these steps is a possible solution to the issue, check the status of the device after completeing each step.

!. Restart the computer
2. Close all applications that may be running
3. Temporarily disable any antivirus software you may be running
4. Reset the Nav-U unit by placing a safty pin or something likewise into the reset channel and hold down for approx. 15 sec.
5. Uninstall Microsoft ActiveSync from the Add/ Remove programs and then reinstall it using the Nav-U DVD
6. If possible, test it on another computer.

The troubleshooting steps listed above should resolve your isue. if not, service may be required.The Sony eService Web site at http://eservice.sony.com/ can assist you in obtaining service from a Sony Service Center or locating a Sony authorized dealer.

By MS Active sync from computer delete file Mounted Volume/my flash/sony/nav-u.exe (the folder SONY is hidden, you must set show hidden files in your comuter first). And then replace old navi file by exe file of total commander CE version ( download is free on site of developer) .You must rename the totalcmd.exe to nav-u.exe. Now after reboot is allowed everything, including executing any other navi software like tomtom, igo, navigon and many other (multimedia players). The oficial navi (old navigon) by sony is not so good in compare with new navi soft. .. enjoy.


PS> the USB active sinc conn is working only if you plug with usb also power supply, in every other cases is written message "connection cancel" so you must plug the power supply

My sat nav map is over 12months old how do i update to new map. my sat nav is medion


OK, what you need to do, is go to the GPS Manufacturers website, download the latest software for your unit and PC. Install this as Administrator. Now connect up your GPS via the USB cable. Then turn on the GPS, then update using this software, Reboot and using it's now, updated software, download, any updates, as may be, from the website, it is all done through the GPS's internal program.

How do you download updated maps to he garmin nuvi


You can purchase map updates from stores that sell the units, or new this year you can buy updates for the life of your unit from the Garmin website which cost $120. You can get up to 4 updates per year. If you wish you can just purchase a single update for $70.

http://www.garmin.com/garmin/cms/us/maps/numaps-lifetime

Also download the Garmin Webupdater software from the site which allows you to connect the Nuvi to your computer and will give you free software updates for the unit itself.

Can i download free maps for my 2year old garminnuvi200 satnav and from which site


You can update mapping software on most sat nav units to take into account alterations to the road network. Either from your PC, in the case of portable sat navs; or via your phones GPRS connection, in the case of phone models. Always check the level of mapping that comes with your equipment in the first place. Is it up-to-date?
. Every couple of years Garmin will release a map update, which you can get on DVD or download - you've got to pay for it though!
