E570 with GPS and Navi

If you're refering to upgrading your Navigation software, QuickGPSfix data and/or your current (out-dated) map, you can do it by connecting to the TomTom website (www.TomTom.com) using the TomTom HOME or MyDrive Connect software, depending on the model/version of your GPS device.

If you're refering to upgrading your GPS hardware/equipment, to have more capability/features, the device is not hardware upgradable, except for adding/using an SD card with a higher storage/memory capacity (to store more info/maps, etc.) ... provided you have a GPS device with an SD card slot.

You'll want to consider buying a newer model with more capabilities / features than what you have now.

Unfortunately Nextar does not offer an update for your unit. See units with available updates below.

You have a few corrupted files internally. Contact Rand Support to
obtain a new update SD Card to upgrade you to the new version and maps. The update SD Card will not remove your user
data. Be sure to have your serial number handy,
(back side, bottom right).

this is a broblem with the softwear it dose not shut the gps off and run the thin dead you can upgrade the softwear to igo 8.34

hard reset the device, turn it off on reset button/ power on/off...then wait for a minute before you switch it on...bingo! or else reinstall the software of your device..or else hardware issue (but this is more software issue).

This took me weeks to solve because they dont give you a decent manual. It is necessary to have a good map on your sd card. You have to go into your map setup software and tell it which serial port and baud rate to use. otherwise it will display as you state.

I'm in Australia, so if you're not you will need to go to the navman website and select your country, then find the update. The update is done through the NavDesk software I think.

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.

Weird! I would try an alternative Windows CE MP3 player such as Xaudio or PalmPlayer to see if they do the same thing. I have trouble believing it's hardware related because AFAIK the MP3 decoding is all done in software, but I guess it's possible.
