Thought I'd pass this along regarding the IPAQ Navigator System software and WM5. Recently upgraded my hx4705 to WM5 and when trying to install the software, had a hell of a time. Maps loaded okay but the software app itself would never stick. The GPS BT receiver works with other GPS trial software I downloaded as a test. Below is a response from NAVTEQ regarding my inquiry on WM5 compatibility.
