The added steps below are only required for those needing conversion from NMEA to Garmin format (e.g. Some programs may require a helper like Curioustech Xport to split the NMEA data flow or send it via a suitable com port. This may be all you need to supply NMEA data to other programs. A GPS control program like Globalsat GPSInfo should show NMEA data flow on the relevant com port, and may calculate a position faster than Connection Manager. If you are outside with a good view of the sky, the Connection Manager > GPS tab may even show a position fix (can be slow). In Device Manager > Ports, you should see the NMEA module assigned to a com port. On first use, configure it to allow GPS information flow to other applications (this setting is saved). Start HP Connection Manager to power up the WWAN / GPS chip.Check that the wireless power switch at front left of the computer is ‘On’ (blue LED).Enabling may keep the sensor powered to show position in applications like Google Maps? Not needed for programs that have GPS Start / Stop control.

HP un2420 NMEA will also show under Control Panel > Location and Other Sensors.Connection Manager may also be set to run on Windows start.

Additional Services will be active for “Qualcomm Gobi 2000…” and “smmanager for HP”.

Device Manager will show HP un2420 under Modems and under Network adapters and under Ports (one COM port for Diagnostics and one for NMEA).

HP Connection Manager can power on/off the un2402 module, and show WWAN / GPS status.

In Win7 pro32, it required the WWAN AutoConfig service and ‘hidden’ WAN miniport drivers to be enabled (only a problem if you have at some time disabled them).Īfter successful installation of these drivers (and reboot): Initial set-up required installation of HP Connection Manager and Qualcomm Gobi drivers (e.g.

The approaches below were tested on a HP mini 5102. Some people may be interested to use it to supply position data to a program such as Garmin nRoute for real-time position display even if they have no use (and no installed sim card) for the WWAN module on the same chip. The GPS module has good sensitivity (close to SIRF III in my simple tests). The Qualcomm Gobi 2000 is a widely used WWAN / GPS combo device. To use the GPS chip in the Qualcomm Gobi 2000 (HP un2420) WWAN device :
