I'm not sure I understand your fix.

The other day, when I was looking at the new Kenwood unit, I wanted to see if the Monsoon's clock had any affect on the computer's day/date display.

I set the clock for 11:59pm and the instant it changed to midnight, the computer's day/date display instantly changed dates. Thus, it appears to me that the stereo and the computer display are "communicating".

I guess what I want to find out is, is this a common output on an aftermarket stereo like the Kenwood, or will the computer's day/date display just no longer display the day/date any longer without input from the stereo?
