1. Product Overview
The HOLUX GR-239 Bluetooth GPS Receiver is a complete GPS solution featuring Bluetooth and UART interface for high sensitivity to tracking signals. The GR-239 design is based on SiRF Star III Single Chip Architecture and is powered directly from a cigarette lighter, which saves the trouble of charging the device.
The GR-239 is a dual-function GPS receiver. It not only transmit satellite information through the PDA or Notebook with Bluetooth capability but is also a G-Mouse GPS receiver and through a USB data cable to deliver satellite signal to the device without Bluetooth capability.
This positioning application meets your needs with car navigation, mapping, surveying, security, agriculture and features needed. The GR-239 connects to other device through Bluetooth or Serial Port Profile (SPP). It supports NMEA 2.2 output protocol, which helps to save satellite information such as the satellite signal status, the last location, date and time of last use.
With low power consumption, the GR-239 tracks up to 20 satellites at a time, re-acquires satellite signals in 100 ms and updates position data every second. Trickle-Power allows the instantaneous start and Push-to-Fix permits users to obtain a quick position fix even if the receiver is usually off.

You need to install a driver for the USB data cable before using it to connect to your notebook or PC for data transfer.
System Requirement
CPU: IBM, Pentium, or other compatible PC
Memory: 16 MB or above
System: Windows 98/ME/2000/XP
Installation:
- Copy the driver file from <GR-239→ Choose the Language you want to install → USB Driver→Win98_2k_XP ∪USB-V2.1.0.exe from the tool CD provided to the hard disk on your computer.
- Run the USB-V2.1.0.exe file.
- Connect the USB data cable to the USB port of your computer. Your computer will detect a plug & play device and start installation automatically.
After the software installation has been completed, confirm the COM Port generated by your computer for the GR-239 USB device.
- Click
→ → . - In Control Panel, select
to display the System Properties window. Next, click tab. - Click
to display a list of all the hardware installed on your computer. - Select
and check if <USB to Serial Port (COM#), the virtual COM Port created by the USB driver is in the list. If so, the installation is successful and you can start using the GR-239.
Notes:
- The “#” represents the virtual COM port number. The default value for general UPS device is COM1. You need to configure the COM Port number in your navigation software in accordance with the USB COM port number generated by your computer. Failure to do so will result in the navigation software not being able to receive satellite signals.
- It is prohibited to operate this system while driving your car.
- Before you setting, while the car is stationary, ensure that you have searched for and fixed your position using the positioning function.
- GPS signals are unable to go through non-transparent objects, such as tall buildings, tunnels, underpasses, and forests. Bad weather may also effect the signal reception. If your car window heat shield contains metal, the receiver will not be able to pick up GPS signals.
- All wireless communication products, such as mobile phones and speed limit warning systems will interfere with the communication satellite and will affect signal reception.
- For further information, refer to the user's manual in the supplied CD-ROM.
- GR-239 passkey: 0000 (For security purpose, some PDAs will prompt users for the GR-239 passkey.)
5. Troubleshooting
| Problems | Reasons | Methods |
| No position output but the timer is counting. | Weak or no GPS signal can be received at the current location. | Connect an external antenna (optional) to the connector on top of your GR-239, and then run the GPSViewer with cold start again. |
| When outdoors, GPS signal is blocked by building or car roof. | Go to an open space and run GPSViewer Cold start function and try again, or connect an external antenna to improve signal reception. | |
| GPS doesn’t work. | Bluetooth function unstable. | Turn the GR-239 off and on again. Restart your PDA or PC. If it still fails to operate, reinstall the software as described in 4.5 Bluetooth Installation. |
| COM port cannot detect the GR-239 Bluetooth Receiver. | Incomplete installation or other device is using the same COM port. | Complete the installation of the GR-239 Bluetooth Receiver or stop the other device which is using the COM port. |
| Cannot detect GR-239 Bluetooth Receiver. | Poor connection. | Restart your PDA or PC and make sure the device is connected correctly. |
