I was driving along at night with the music cranked. I could not hear the alert. I have a remote display but have not done the color LED modification yet. Just been too lazy I guess. But I got pissed off when I excused a Ka band alert for a K. Mike V really needs to do something about the mono tone band alert LEDs, both to the main RD and the remote. Just my two cents cause I almost got screwed coming home from bowling tonight!
