This mirror is actually a customers mirror that was sent to me for repair of the FZV antenna amplifier because he could not use the key fob remote. It's now fixed and before I put it all back together I thought I'd snap a few pictures. He was very happy to have the function of his key remote back without spending $631.13 for a new mirror plus installation.
This mirror has 315 MHz remote receiver (FZV)
for the key fob, auto dimming feature, Home Link garage door opener and SOS
button.
On the left is the module for the HomeLink garage door opener board. In the center bottom is the FZV receiver. On the right is the module for the SOS.
This is the picture of the back of the actual auto dimming mirror assembly. It's basically one big LCD display pixel.
Below is the FZV antenna amplifier which is only
in the rear view mirrors used in Convertibles. Normally the FZV amp is in the
drivers side C-pillar, but, in the convertible it's in the rear view mirror.
