I posted this install on Corvette Forum, as part of a huge sound-deadening and stereo upgrade project I just finished <CLICK HERE>:
I had originally hacked my own RAA (control knob & speaker wired-out to remote mounts), but when I switched it to my new car -the piezo speaker wouldn't work, so I ordered it hacked from Radar-Mirror.com, rather than starting all over!
26) VALENTINE ONE & Z-BOOST: Also hacked my Valentine-One radar detector: 1) Cut and resoldered the Concealed Display (CD) down to ¼” thick and mounted it on top of the steering column. 2) Ordered a custom RemoteAudioAdaptor (RAA) from Radar-Mirror <CLICK HERE> where the control knob is wired-out as a remote, mounting that to the center console next to the mag-ride knob, and they also wired-out the mini-speaker (you have to ask them to do this part), I mounted it inside the top-left-center air duct, pointing at my head-ears, this way I control the whole detector from the one remote switch. 3) Mounted the V1 main unit to a concealed area next to the OnStar brick, where it is somewhat behind the tint, turn the volumes all the way down and sound will only come from the duct-speaker ... the power module is behind the HU - stealthy! I also installed the Wi-Ex Z-Boost YX230 Car-Extender, that boosts your cell-phone antenna by up to 6-times. I mounted the base unit under the carpet on the rear deck behind the passenger seat (below the vert-top controls), then ran the receiver pad from there to the top inside of the center dash. The antenna was run down the right side to the back, through the rear wall and mounted on the inside top of the rear bumper. Powered by clipping into the 12v RAP and ground block. It works amazingly well.
