AvNav implementation in OP2

[wellenvogel]

Hmm,
First: Do NOT! install the -raspi on openplotter. It will potentially break your network settings and other stuff!

For the avnav package itself.
What exactly did you do after installing?
It's just important that you:
(1) restarted AvNav after installing (e.g. using the AvNav installer)
(2) reload the WebPage (just use shift + reload to be sure)
If you did not change the configuration everything should work as before.
To sort things out it would be good to get an understanding what is shown on your browser (and what not).

For the deeper integration with SK:
You would need to configure this at the new AVNSignalKHandler (description is just under work).
It will (intentionally) not do this by it's own.

And BTW: What browser are you using, what layout,...
