I'm not sure how much this really works but what I did is I thought my car didn't have good enough reception from the controller and wanted it to do better so what I did was took a cell phone booster (like the ones you see on tv the little gold ones) and put it on the inside of my body. I noticed there was an improvement in my car but I'm not 100% sure. Has anyone else tried this???? You can get them off of ebay for a penny.
