2005 TL Nav System - Some Nav System Issues

I've had the car almost 2 years now, but only recently have had to use the nav system intensely. I've encountered two interesting things, both might be bugs:
1. If I set the illumination intensity to "Auto" and leave for work in the dark, once the sun comes up (even if I turn off the headlights), the illlumination intensity does not go to Day unless I switch to some other screen, such as Audio and then switch back to the Nav map view. I presume the code only reads the light intensity sensor when some sort of input is received from the user from the control panel.
2. I an unable to turn off the verbal navagation voice. Setting it to off has no effect. I can set it to off and restart the car and it is still on. Turning it on and then off also has no effect.
Has anybody else seen either of these? I only found one place in set up (screen 3) to control the voice. Did I miss something?

Haven't seen your problems, but it reminds me of a question...
We've got a 2004 TL, and I'd like to know if there's a way to edit a location I've put into the nav system so it can have a name like "Bob's House," instead of just the street address..?

far as the verbal goes I turned the volume on her voice down all the way, never did try shutting it off.

Good point.
Navi system (software) upgrades occur once per year sometime in the fall... period. Occasionally a "patch upgrade" might happen sooner, but this is rare.
For the guy with the illumination problem try turning the 'dash illumination' down one click from max bright. I think that will fix your problem.
