I recently picked up an escort 9500ix with a serial in the 22xxx range. I updated the firmware to the latest version as well. I'm having an interesting phenomenon.
If I am in auto OR highway mode, even with GPS turned off when I pull up to say a CVS with K-band door openers, I'll first hear a brief ramp-up... then it goes silent. I don't mean "Auto-mute" sound level, I mean silent not a peep.
I can see a full blast K-band alert on the display, but the detector doesn't make a sound.
Is this normal for the detector, or did I pick up a lemon?
