Okay... I finally got the perfect radar detector setup on my FZ6. I started off with it taped to the windscreen and could barely hear it, with an LED that I could not see.
Now... I spraypainted it flat black (with permission from Escort). I bolted it to the winscreen with rubber washers to dull out some vibration.Underneath I have thick velco to help with vibration from underneath. I bought a 12 volt speaker from Escort which I mounted under the dash. The RD and the speaker come on when the ignition is switched to ON, otherwise both are off.
It looks super clean. It is very secure. It is super loud... I get strange looks at intersections where it goes off. I can hear it at 8k RPMs with 20mph headwinds.
