I picked up the car tonight after having a local high-end install shop do the work for me. Sorry its so dirty, we still have tons of snow here and the roads are wet and messy...
As I said, we are still clinging to winter here and my money tree in the back yard is still a bit bare, so I didn't have them get "too" custom, but I am happy with the way it turned out. They also installed my LI, but it appears as though there are some issues with the way they crimped the connectors on, so I'm going to take it back tomorrow and have it corrected.
Radar Antenna / LI Heads
They mounted the antenna behind my bumper cover, on the dirver's side, just inboard of the driver's side headlight. I am worried that it may be a tad low, as it looks like it may be in sort of a "corner". I'll watch it and if needed, will raise it up an inch or so. It seemed to have no problem picking up some X and K falses on the way home
You can also see the LI heads mounted on the lower grill (yes they're level - they just look crooked due to the picture). It is approximately 18 inches from the sensor to just above the top of the Cadillac crest in the grill, and likewise about 18 inches from the sensor to just above the HID in the headlight assembly. Hopefully they work ok there. We were going to mount them higher, at the top corner of the upper grill, but they protruded a bit too much for my liking. The shop occasionally gets their hands on a Lidar gun, so when they do, I'll have them test it:
They were pretty clever with the GPS antenna. I had orignally asked that they put it on the rear shelf, as I thought it needed to be able to "see" the sky, however they placed it under part of the front dash cover. The smaller square box with the silver panel beneath it is the stock GM GPS antenna, so clearly there are no issues placing it under the dash cover. It had no problems acquiring a lock on the drive home.
They mounted the control panel on my overhead console, in the vicinity of the map lights. The round switch is for the LI:
I didn't want anything fancy, and felt that on top of the RVM would be a good spot for my liking. I don't have a pic handy, but it is just stuck on top of my mirror with double sided tape.
The brain is under dash, as is the speaker. The USB upgrade connection is behind the plastic panel on the end of my dash. I may move it so that I don't have to constantyl pop off the panel everytime I want to update it, but I'll wait and see just how often I end up doing that.
