So I have done 4 head units and 2 TX's sensors front & rear plus as you know the Uniden R3 all of which you can see in my pics. I really need now to test for any punch throughs. Ive done 3 major road trips, but thus far no alarms have gone off with ALP. The Uniden R3 has served me well, as well as WAZE. I have reached out for TESTING but no replies- too bad. I have to find someone who can make sure I have the best coverage for the investment I have put into this. Again Im in the Tampa Bay Fl area.
