I took the risk and installed the Upgrade to V600002.exe
My first findings:
During Installation of upgrade the path of privious installation is found. /Wasn't the case with V6.01.000
Version read on Software boot-label (I don't know how to name it otherwise) is V6.01.001.
As the recognizing of installation path already suggested, the login-Data is now recognized.
The auto connect option by using e.g. "C:\AirNav Systems\AirNav RadarBox\ANRB.exe" /connect is working too.
Still valid:
IAS: permanent data,
GS: Data every few seconds for some hundred mili seconds, the rest of time 0kt.
Label on map shows ground speed.
Perhaps Airnav should consider to implement a check which data is present and then display IAS data or GS within the aircraft label on map.
So far no problems or obvious improvements detected.
I'll stay with V6.01.001 to see what happens.
