Struggling with volume control

[Anonymouse]

I've read through the posts from others with volume issues (ie MRA too soft relative to music playing) but I'm still confused.

1. On the iPhone version of MRA I've tried adjusting Settings > Audio > Volume level. But it keeps springing back to its previous level -- if it's 50% and I wind it up to 100%, it says to tap the volume button; I do that and it goes back to 50% again. I've tried doing this during an announcement but the same thing happens.

2. Another issue is that when there is no music playing (ie it has been paused for a while) there are no navigation messages. I suspect this might be a quirk of the bluetooth player (I'm driving a Morgan Plus Four with a Sennheiser system that just has a volume control and amp, nothing else). Is there a way to make MRA "wake up" the audio system when it has an announcement to make?

Thanks for any advice on these two issues.
