Unlocking Nextar GPS W3G-01
for those that need it:
GPS “nmea” on
com port 6
serial port 2
After finding out that many GPS units actually run Windows CE at its core I decided to get the cheapest GPS unit I could find and unlock it.
Normally you only have access to the GPS software provided by the manufacturer. In an unlocked unit you have access to any software available for the windows CE environment. Including, but not limited to GPS navigation, multimedia playback, and games.
The Nextar W3G-01 is different then the W3G. Searching online through forums and web pages yielded very little information. Here I hope to provide my own research, along with basic information on how to unlock this unit. Be aware that this will probably void your warranty.
Operating System: Windows CE 4.2
Processor: Intel PXA255 300MHz
RAM: 64 MB
Internal Storage: 1 GB
Battery: Built-in Lithium 1200 mAH
Screen: 3.5″ 320×240 touchscreen LCD
SD/MMC card reader
3.5mm headphone jack
Note: the Operating System is read only, any settings or changes made to the core operating system will be reset on reboot)
1. Download and install ActiveSync or Windows Mobile Device Center
2. Turn GPS unit on, wait for the unit to fully boot then plug in via a USB port
6. Find and open AUTORUN.INF
7. Delete all contents and replace with “navigation = \Windows\explorer.exe” without quotes.
This will allow the unit to directly start up in the Windows 4.2 desktop environment. This command can be edited to start an application from an SD card or from internal memory. for example “navigation = \MMC_Storage\gps\navigator.exe” would start the program “navigator.exe” from an SD memory card under a folder named gps.
8. Save to Desktop or any easily accesible location on your computer.
(You will not be able to save directly to the GPS navigator from notepad)
