I have a Nokia 920, BlueAnt ST3, and Camry Hybrid 2007.
All work perfectly with WP8.0, especially the ST3.
Now Cortana cannot call anyone because she cannot hear/understand what I say.
If I dial via the phone, the speakerphone volume is to low to use, and the mic is also turned way down. I tried adjusting the volume on the phone, and it was max for "media+apps". No setting for Bluetooth volume.

Without Bluetooth, everything works fine.

Right now, no usable handsfree for either of my cars.

Lumia 920, Jawbone by Era - same problem. Cortana won't understand me and people I call claim my voice is about 30% quieter.

Same here. I have the 1020 and the new Era. They did just recently update the Era. Made no difference.

Same problem here, Lumia 1520.3. Cortana won't work any longer via bluetooth. Wife says she can't hear me anymore.

Same issue here very low volume

Hope there is a fix shortly as It makes it near useless in hands free car kits. Especially running around on the farm with other noises. Resorted to having headphones in so I can actually hear people while on the phone.

i have always had a low volume over bluetooth issue in my car with my 920 (and 900 before) in my car, volume at 16 is really loud for everything, but I have to crank it to 26 to use speakerphone in the car via bluetooth.

Has anyone ever figured this out, I tried adjust everything on my Lumia 830 and when I'm connected to bluetooth in my car everything plenty loud except for cortana, and I use cortana to read my texts out loud and I have to raise the volume on my radio to a ridiculous amount.

I also have a problem with the volume level when using the SundayTicket app for DirecTV. I can get the volume up to a comfortable level with or without Bluetooth headset. Everything is set to max but any noise around me and I just cannot hear it well.

With my 1520 ATT DP 8.1 and my BT (Jabra Wave ) while BT is on if I push the volume up/down the dialog bar5 opens and shows Bluetooth volume. and can be adjusted. Maybe this is a new feature for 8.1.1 and not available now for 8.0.
