Managed to get a couple of "electronic: tts voices working

Navigation voice is ok when USB, SD is providing background music (even though volume is tied to music volume

When Radio is on TTS voice (and non tts voice) is very soft.
Played around with svox etc, etc, but nothing makes any difference.
I use Radio 90% of the time when navigating so want warnings and route to be heard.
Any clues how to fix?
