How to download latest US map, NAV-U70

Sorry, here is the bad new,
Sony Canada told me that my NAV-U70 does NOT have sufficient memory to drive the next Navteq update (which will be offered by Sony) and guess what, that update is not even available yet, may be in a couple months or weeks, Sony don't even know when!!!
After spending over 500 CDN$ (tax incl) for my NAV-U70 2 years ago at Best Buy store, Sony Canada do not care at all either Best Buy, they offered me 100$ which I can use on other Sony products, well... will I buy something else from Sony... not sure! :-(

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:

!. 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 can assist you in obtaining service from a Sony Service Center or locating a Sony authorized dealer.

Nav-u.exe Exception

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.
