Implement Home Zone (voice navigation mutes until you leave a specified radius from home)
I love the voice prompts that accompany navigation and I like to use them when going somewhere new. But i don't need them to tell me how to get out of my neighborhood or how to get to the freeway. I find the constant unnecessary interruptions quite annoying.
I would love to set a "Home Zone" of say... 5 miles.
At home i enter my destination address.
Maybe i hear a very high-level instruction, or nothing at all. "Get on I-5 north"
Once I'm out of that 5 mile radius, the detailed nav prompts kick in.
