My phone works great for driving directions. I plug it in and turn up the volume when I'm driving by myself. I plug it in and turn off the volume and give it to another human to tell me what to do when I have passengers I can trust to navigate for me. I only really need to use the phone for navigation like 2 or 3 times per month, at most. My daily commute to the office never has traffic and in nicer weather times I often ride my bike.
