Background color/beeping tzt3

[Gator75]

The only options for daytime and nighttime fish finder backgrounds for me are black, white, dark blue and light blue. How can I get the furuno blue?

Bonus question:

When I turn my key off, the gps chirps/beeps. How do I turn that off?

Thanks.

Is your software entirely up to date? I don't remember exactly which version brought the additional blue color to the TZT 3 displays. I believe it was 2.3 or something like that, but they are presently on v3.5 which opens up a ton of new capabilities.
