Chime volume limits

I'm trying to turn the chime volume way down in the Settings panel for it, and the allowable range of values for it is limited to something like 25-35. I can't turn it down to anything less than 25 (the full bar is shown, but everything to the left of 25 and to the right of 35 is greyed out/inactive and unavailable). Why would they show a full range of 0-100 but only allow adjustment within a very narrow range of volumes?

I was looking at that also. People on the Volt forums have complained about the chime/beep on their cars.

When I saw your post I was sure hoping someone had a quick answer.

Argh... it's just super frustrating that the volume slider goes from 0-100 but the functional range is only 20% of that. WTF?

At least I finally managed to get the Nav voice turned up a bit. Took many tries, but it finally worked.
