I believe I read somewhere on this site that there was a retro fit board.
The SIM board does work It might just be the cable end needs to be replaced.
and not the plugs on the SIM board. I am being over critical of the Vantage pro I want to make sure people are aware of the some of the possible glitches.
It is still in service and working except the Humidity sensor.
The only time I have a connection problem is when I do a routine cleaning and open the bottom cover
where the wires connect, Sometimes I loose the signal and have to un-plug and re-plug in the cable
for the wind speed or temperature.
