I have a Stir Plus just installed on a 2008 Toyota Camry SE. The question I have is does installing the sensor behind the honeycomb grill affect the performance, or is something else wrong. I have had a couple KA alerts only after the LEO was clearly in site ( 100 Yrds give or take) Also the detector has pop on and all the other factory settings are the same. The sens is in autoscan also. Any hep is greatly appriciated. Thanks in advance for the help.
