Got my second STi-R Plus installed today by a professional installer. Was in the shop with them overseeing the whole install. Everything went flawless, 2 hours and out the door. I installed the antenna in a location I had my Redline before. This is my second STi-R Plus. The only thing I notice with this one compared to my first one is it hardly ever goes off. I know when they normally do go off, and I've noticed this one is eeerily silent. I've got two K 24.1??? alerts because I have it in Spec mode, but this thing is silent otherwise. I checked the interface and all the cables are plugged in all the way in the correct slots. I guess I'll give it a couple of days and see if it goes off more. All functions seem to be working properly, GPS, Autolock etc, so I don't know if this is just an one time thing or not. I passed two LEO's on the way home from the install, one with Radar, and Nada. I know that not all LEO's with Radar have it on all the time, this one was an OPP LEO around Toronto. Anyone else have a similar experience. Only thing I haven't done is connect it to Detector Tools to merge the database and load the software. I sold my laptop that had Windows 7 on it. I have a Macbook Pro and I can't use Detector Tools on that.
