Any reason why I can't get my settings to save? Everytime I turn on my car (with the exception of a few times) I lose all my settings I had previously. I lose all presets, sound settings, clock setting, the beep tone from screen touch..everything is reset to factory default?

How do we save settings on the d3??

You have a defective connection with the yellow power wire. Either that or the unit is defective. I am betting on the wire though.
