Yup, they both disappear if we remove the external antenna.
The GPS circuit should get a lot simpler - we also don't need
the antenna power switch anymore.

Right !

Yup. I haven't looked, but there probably isn't one with two ground
contacts in the KiCad libraries.

We'll may receive the whole WLAN module pre-assembled, so I don't
think we need symbols for its components right now. But we'll have
to revisit this question once more details are known.

This one gets removed. The codec already contains one, we just have
to use it :-)
