And so do most sat nav users I see. :lol:

I personally can't stand the bright daytime colours blinding me at night. Even the Columbus I find too bright at night in night mode. Wearing glasses doesn't help I find.

Does not the instrument lighting rheostat adjust the Columbus screen brightness?

Yes, but when it is on low it won't go any dimmer. The display is also on it darkest setting.

Tom Tom is the biggest pain, I can and do live with the Columbus. I turn the brightness right down to almost off on the iPhone or iPad and use night settings. Most people I see leave it on day settings and very bright as well. I am blinded and I'm in the car behind. :lol:
