Motorola NMEA Device (COM20) Driver

The Motorola NMEA Device (COM20) driver helps Windows recognize a USB-connected NMEA serial interface so compatible software can access navigation data from the device. You may need it if Device Manager shows an unrecognized interface, the COM20 port is unavailable, or your navigation application cannot communicate with the connected Motorola hardware. This listing identifies Qualcomm Atheros as the vendor and lists support for Windows 10, 8.1, 7, Vista, and XP.

Key Features

• Enables recognition of the device’s USB-to-serial NMEA interface, allowing compatible applications to communicate through a COM port.
• Supports access to NMEA navigation messages when the connected hardware and its operating mode provide them.
• Helps resolve missing-driver issues affecting the Motorola NMEA interface in Device Manager.
• Provides a driver option for the listed Windows versions, subject to matching hardware IDs and system architecture.

How to Install Motorola NMEA Device (COM20) Driver

1. Check your Windows version and whether it is 32-bit or 64-bit. In Device Manager, open the device’s Properties and check Hardware Ids under the Details tab to confirm that the package matches your hardware.
2. Before starting your Motorola NMEA Device (COM20) driver download for Windows, review the package’s compatibility information. Select the latest version that explicitly supports your device and operating system; a free download label alone does not establish compatibility or safety.
3. Download and extract the package if it is compressed. Scan it with your security software, then run the included installer if one is provided.
4. If there is no installer, right-click the device in Device Manager, select Update driver, and choose Browse my computer for drivers. Point Windows to the extracted folder and follow the prompts to install the matching driver.
5. Reconnect the device and restart Windows if prompted. Check its assigned port under Ports (COM & LPT), then select that port in your application. Windows may assign a number other than COM20.

Keep the driver updated when a compatible release addresses a connection problem or improves support for your system. For Windows 10/11 systems, verify compatibility separately: Windows 10 is listed here, but Windows 11 support is not confirmed. Avoid forcing an unsupported update, and keep the previous working package available in case you need to roll back.
