Microsoft has released a new version of Windows Embedded designed especially for portable navigation devices.

Windows Embedded NavReady 2009 will be offered to manufacturers and then pre-loaded onto the devices.

The move is the latest effort by Microsoft to overhaul its embedded software division and encourage developers to write code for the platform, which covers ultra-portable devices, kiosks and point-of-sale systems.

Microsoft hopes that its presence in the desktop and embedded market will translate well into the portable navigation field, allowing OEMs to build more powerful devices in less time.

The new Windows Embedded OS will allow navigation devices to better synchronise with Bluetooth devices, and improve search and traffic functionality.

The software will also interact with PCs and other embedded devices to act as a second monitor by way of Windows SideShow.

"Our commitment to this segment has always been about providing the platform and tools that give our OEM partners the most innovative technologies, while reducing the complexity of development," said Kevin Dallas, general manager of Microsoft's Windows Embedded business.

"We firmly believe that the release of Windows Embedded NavReady 2009 helps us fulfil this promise by taking the portable navigation experience to the next level."
