I won't chime in on my thoughts of the NAV capabilities because I am not a fan. However, I do have a couple of questions that may make my use of the NAV a little more tolerable:
1) Can you turn off the voice prompts so that you don't have the break in music when directions are being given?
2) Is there anyway to display a clock or an ETA for the destination?
3) Is there a way to display and use the NAV without playing a music source? I feel like the music is on by default and I have to mute the music source just to have the NAV on display?
I probably should read the manual.
