HiFi installed

OK
I'm a little confused
Does the Voice Alert not indicate you are being targeted? Or do you need to hear the buzzer?
Also, when does the auto-off count down start?
At the beginning of the voice alert or the buzzer?

The alert from the Hi Fi Control Set indicates that you have been targeted (at some point in the past). But if you were to pick up momentary scatter, you wouldn't be able to distinguish it from being targeted continuously from the audio alone, when you're in Pro Mode. You can, however, always look at the LED for that information.

The standard control set also had issues though. If you were to pick up momentary scatter and you were running Pro Mode, the LED would very quickly flash red or yellow, perhaps for as little as 0.1 seconds. Unless you were staring straight at the LED while driving, you'd be able to tell you were hit by something, but you wouldn't be able to tell what direction it came from. With the Hi Fi Control Set, it'll announce "ahead" or "behind".
