Not so far. No interest. It has to be mass widespread to have a real need for that

Driver and firmware (OS) combination deliver data to the software.
Yes, the Navigon can run on a standard WinCE device, but no one (ok, most) wants to bother with that (limited features)

PortSplitter is dedicated to SirfAtlas only.
SiGe SE4150L is RF receiver, "which improves sensitivity and interference resistance for GPS products...".
“...SE4150L GPS receiver IC, we worked closely with SiRF Technology to ensure that the SE4150L would interface seamlessly with the integrated GPS baseband of the SiRFatlas and SiRFprima SoC family
...
The SE4150L combined with the SiRFprima SoC offers superior performance and high resistance to jamming and co-located interference in challenging environments, such as mobile internet devices, connected PNDs and other GPS enhanced multifunction systems on which the SiRFprima SoC excels...
