Jamesmonkey--you were spot-on right!!
For all other TT1 users having this problem, do this:
Connect your TT1 to the computer, When TomTom Home comes up, look on the left side under Options and More...Click on My One.
Next you will need to click on the "On Switch"
Tap anywhere on the map,
Tap on Change Preferences,
Tap on the grey triangle (more options) two times,
You should now see Docking Preferences (this is greyed out when not connected to the computer...and the reason I couldn't figure it out).
Tap on Docking Preferences,
and finally UNCHECK "Link night view to headlights".
Once again, thanks to Jamesmonkey (You Da Man!!)
