The STi-R Plus is a great detector, don't get me wrong, but mine keeps malfunctioning. Every time I turn X band on (when I go through states that still use it, I need coverage), it constantly goes off. I will be in Bumf*ck, PA, and it will be screaming "X BAND!".
I have turned X band on, on the V1, to confirm whether or not the issue was just the STi-R Plus. Sadly, my V1 never made a peep . Has anyone else had this issue before, with a standard STi-R, STi-R Plus, or the 9500ci? I guess I'll be sending mine back to belscort .
