2001 - Automatic Headlight Sensor/Switch & Interior Light

Decided to browse the Owner's Manual Last night and it seems that the sensor/ switch for the automatic headlights can be adjusted. I want them to come on earlier (i.e. when it's still a little brighter outside). What do I need to get this done?

I also read that the interior hood light can be set to come on when the car is unlocked remotely using the key fob. Again, what's the process to turn this feature on.

I believe those are all parameters that only a dealer can adjust

You can get the techstream setup. I made some changes to mine with the setup I had for my GX470. I don't recall seeing a setup for the auto headlights. I guess I should check it again.

I did some research last night and the techstream should be able to do it. Does anyone have a link to a free version?
