I have a fabia3 with Amundsen system.
Now I want to set the ringer volume of the phone, can someone explain how I can do that.
I would also like to know whether you can customize ringtones.

You can change the ring tone

In the phone screen puck options and it's in there

A few nice tranquil ones to choose from

Don't recall seeing a volume but I'll check for you tomorrow

You can adjust it when you being called using the volume wheel i think
