Everything seems to still work with the buttons it talks but after one warning ticket then a real one. It will not alert on anything no laser no radar even the cheap construction speed reminder signs i.e speed limit / your speed nothing

Re: earlywarning EW3001 won't give me a warning
This is because the Sunkyong Early Warning radar detector is an absolute piece of junk in terms of actual radar detection performance. It performance is dismal compared to any product manufactured by Bel, Escort, Whistler's higher end products, or Valentine Research. Let me guess -- you bought your Early Warning RD off of eBay.

Laser is very sensitive to false alarms often set off when driving by an airport, or military base. Set your laser on City Mode and pay attention exactly where it goes off. Mine goes off constantly in the same place which is a air force base in Tucson, AZ. Unless you drive like crazy shut it off in the city although the cops like to use a hand held one in school zones. In 6 years of driving in Arizona I have had one real laser alert, and other than false alerts, real ones are far and few in between. Check when and where the unit alerts and use different sensitivity settings. One more thing, if your laser warning goes off you already have the ticket since the cops use them at close range unlike the radar bands. Hope this helps.
It's called "Instant on" doppler radar. It's purpose is to defeat radar detectors and as you saw, it can. The system is powered down while the cop is sitting there watching traffic. When he sees someone he thinks is speeding he just taps a button and the unit emits a brief burst of radar and shuts off again. And just that quick he's got your speed. There are some radar detectors that say they can detect these too, but I wouldn't know how truthful that is.
The speaker's voice coil likely has overheated, and now it is rubbing on the insides of the speaker magnet. This causes very garbled sound. All Sunkyong Early Warning radar detectors provide horrible radar detection performance. You should seriously consider getting a much better radar detector.
I suggest that you don't use this product. US designed and manufactured RD models have well over 10 times the detection range, and the unbelievably cheap Early Warning RD will merely give you a false sense of security -- followed soon after by a speeding ticket if you frequently speed. Jump over to radardetector.net for some real advise about radar detectors.
Speed cameras usually are located either at intersections or along roadways. Many red light camera models used at traffic intersections also function as speed cameras. These speed cameras will mail you a speeding citation if the camera thinks that you are speeding. Your GPS navigator is warning you about nearby speed cameras. It displays red as you approach the speed camera location where you could get an automatic electronic ticket if you are speeding.
I looked at another simuilar Detector and read on Digital Compass Calibration and through the process of elimination found that if I Press CITY for 3 sec.'s COMPASS CALIBRATION showed on the display. Then it says TURN YOUR VEHICLE SLOWLY 2 TIMES to CALIBRATE. Then press the CITY button to complete the calibration. Done. It worked my Early Warning EW-3400 Radar Detector's Compass is now Calibrated.
Thanks for asking.
