I found one other topic on this with zero answers. Wondering if anyone else has this issue. Just installed my unit thursday and everything is working fine except navi volume. I have the voice turned to 100% and must have all windows up and really listen to hear what it's telling me. I see several people claiming it's too crazily loud yet mine is too crazily quiet. Like i said I have it turned all the way up, does anyone else know of any other settings? or have smiliar issues?

do you have a sound system or amp controlling the interior speakers??? In my car i have a amp driving the interior speakers and if I set the crossovers to HP i wont hear it . But if i set to full crossover I can hear it loud and clear.

2011 camaro with factory boston sound system (yes it is amplified). Haven't really fooled with any settings but I suppose it could be the way it's set up. I'll take a look on my way to work tomorrow.

im the guy that started the other thread, and I still have the same problem. I have to have the windows up and really listen to hear it. Vol adjust from 0% to 50% fine but anything above 50% sounds just like 50%. Right now my xover is at full. Source is loud and clear. I have to set the mute to full to understand it, even tho I like ATT.

My mute is set to full, and my crossovers are not set to HP. still too quiet....

What about your rear sound?? Is it on?? I find that that when off its low.

rear sound is on as well. I tried to call tech today during lunch but it was a 30 minute wait time...

I too have this same issue.
