Hi Bernardo,
Base coordinates insertion is mostly ruled by the ReachView 3. So the firmware update doesn’t affect it.
In ReachView 3, you can indeed insert only geographic base’s coordinates manually in LLH format. It helps us to wok better with the RTCM3 transmittance. We’re checking how we can allow you to insert your base in different coordinate systems. It’s a bit complicated.
As a workaround, you can go with the flow with Base shift feature. It’s a non-obvious solution, of course, so it’s better to stick with the LLH solution.
