Lets start with my setup. I want all input bad or good please about my setup.I'm a newbie and I want to learn and do it right. I put my radar detector under a cover in the front of the suv that is covering a license plate mount that is not used in my state. I placed 2 jammers in front grill, and one in rear on a black license plate holder. I placed my gps on the top of the vehicle in the middle of two factory mounted onstar antenna and xm radio antenna. Hope the posted pix will explain everything. Thanks in advance for any assistance.
