I was looking at some pictures of the m20 and had a few questions.
Is the speaker and LED 1 unit? the reason I ask sometimes when I see it installed in cars only the led is visable leaving me to believe the speaker is under the panel and there is a hole for the LED to shine through?? can you hear it then?
Also, the mute wire will mute the car stereo when it goes off right? Do you have to use the mute wire?
Another Q, when looking at the phone jack RJ 11 connections coming off the heads they look quite large, how do you get them through a grommet in the firewall without a larger hole?
