Update Sony Nav-U

Windows recommended a file you have to open .bin files to load to my Sony Nav-U NV-U44 unit. I cannot find the file to download that will allow me to open the .bin file, can you help me? When I downloaded the update file it keeps saying file not found and will not download to the unit. I got the backup to go through successfully, but can’t seem to do much more with adding updates or changing the voice prompt. Kate Dubensky

If I understand you correctly, you are trying to open and install updates for your Sony NV-U44 GPS unit that are in a firmware update .bin file you have downloaded. If this is the case, I think the file should be called something like SONYNAVU_U44_1.1.CO.BIN - if that is the case, the latest firmware update I can find was issued 12/15/2008.

Before you can open and install the update files, you need have a Windows operating system, minimum version XP, running on your computer. Next, you will need to download and install a Nav-U Tool that can read and install the files in the update. Here is the link to the Sony Software Updates and Drivers webpage where you can get this tool, as well as the instructions that you need to follow for the installation. Make sure that you read the entire page and verify your system compatibility before proceeding. If you have already installed the Nav-U tool, skip this step. It is also required that the Tool file be installed before the software update file, so you will need to delete the .bin file, install the tool, then re-download the .bin file.

Once this is done, fully charge your Nav-U device before the installation of update files and be sure not to turn off the device or the computer during the process. If you interrupt the installation, the device might require hardware servicing.

When you think you are ready, check the Nav-U device software version. It is important that you don’t download the same version on top of itself.

Make sure the device isn’t connected to the computer and turn it on
Tap the Menu pad to display the main menu
Choose the Settings Menu
Choose General, then scroll to page5/6
Scroll to and choose Firmware Version
Note the version number - if it is higher than the number of the update file you downloaded, stop the installation

Next, to download and install the updates:

Download the .bin file to a temporary directory, and make a note of where you save it
Connect the Nav-U device to the computer
Turn on the Nav-U device and wait for the Connect to PC message to display
Launch the Nav-U Tool software, then click Upgrade System
On the left side of the screen, choose Browse then go to the directory where you saved the .bin file then click OK
In the Name box, choose the 1.01 co NV-U44 (or whatever it is) and click the arrow
Wait for the update file to transfer until the unit displays the Transferring Upgrade file completed.
Finally, the device will shut down and restart - and the process is finished
