With lotta help from users from this forum, especially YCTD, I finally got it done.
Here some pics. It is WELL HIDDEN, one has to look really really hard to locate the RD from outside.
This is where I mounted the RD. Visor is tilted a little. This gives total stealth from rear view.
Front View. Photo has little glare because of the windshield. You have to nearly stand few feet from it to see there's a RD on windshield.
This is where I Cheetah Wireless Fitting Kit AudioNode installed for the Blinder M25and perfect hiding place for the RD when I'm not in the car.
This is the picture of my stereo amplifier behind the driver seat where I used add-a-circuit module to juice up the radar detector. My Benz has fuse box under the hood so I was fortunate to fine such easy power source without cutting into lighter or the other hidden lines in the car. Fuse for the amplifier was 20amp. Since add-a-circuit model is pararell circuit, I've added 3amp fuse to the secondary slot along with the in-line fuse for extra protection. It powered up fine.
Don't laugh. This pic is just for kicks. Believe or not it's very well hidden from all angles here. No.. I am not going to use it for mounting the RD.
Thanks again to all who help me with this issue.
