[Chills]

I mentioned this in another thread, but I am curious if anyone knows why.

Before I installed my nav unit my Box was like the others on here. When I armed my alarm the lights flashed and that's it. Since the install, however, the lights flash and the horn beeps once.

I have no idea why I get the beep. I like the beep. It is reassuring to me that my Boxster says, "I'm armed, so stay away until Chills returns to drive me."

Does anyone have an idea why mine beeps?
