I have a bug in my Mazda 5 when my iPhone is connected to the Bluetooth. If I take a phone call, the volume is fine. But when the call is done, and either myself or the person hangs up, the audible "bee boop" sound is ridiculously loud and scares everyone in the car, no matter what the volume is set to.<p>It's like they need to really sort out and map every single "interrupt" sound that can occur e.g. hang up, amber alert, etc, and ensure that it maps to a correct volume setting that doesn't damage your hearing.
