When installing this radar unit the white wire, the BZ/TUNI, was left unconnected, so whenever the unit starts up and you try to transmit a signal it will give a Bearing Pulse Error (BZ). This wire was connected, but the problem still exists. I've tried to reboot the system with no luck. Does anyone have any ideas as to how to fix this?

When radar detectors proved easily capable of sniffing out radar from miles away, radar gun manufacturers responded by producing instant-on radar or unoffically called "Pulse" radar. In the instant-on mode, the radar's transmitter is placed on hold, ready to fire but not yet producing a signal for detectors to hear. The officer waits until his target is very close (brings a new meaning to "wait till you see the whites of their eyes") then releases the radar from stand by mode and gets a speed reading within a second or so (pulse). In this situation, no detector offers much warning.
There are guns out there that operate just like the instant-on guns of the past but with a very tough twist - POPTM mode! This gun is a normal K and Ka band radar gun detectable by most radar detectors made in the past 30 years, until this gun is placed in POP mode. When the gun is in POP™ Mode and activated, a brief burst of energy, less than 1/15 of a second, is transmitted and the vehicle's speed is quickly acquired. A detector without POP™ Mode detection capability cannot respond to this brief transmission. TIP - When traveling in unfamiliar highways always try to find a vehicle which is traveling at the same rate or faster than you are and keep several car lengths behind them. This way the other vehicle can "flush out the radar".
There are a couple of things that could cause the radar to power off when going into the transmit mode.
The first thing to eliminate is input power. When in the standby mode the radar draws less current than in the tx mode so if you have low voltage for whatever reason, that could cause a shut down. Check all connections and measure the voltage to the unit while it is on.
A problem with the antenna motor or gear box could also be the problem. The antenna doesn't rotate unit the unit is switched to the tx mode. You would need to remove the dome cover (with unit off) and verify that the array will turn freely by hand. Typically, a bad motor will not cause a shut down but a physical obstruction could.
Focus on the power issue because that's the most common problem. Be aware that you need to measure the voltage as close to the radar display as possible and watch the voltage as you switch the radar from standby to transmit for a quick dip in voltage.
Pins look like this: (Top view, not copper side) 1 2 3 4 5 6 7 8 9
1 = Thin white wire from thick white cable (Left input) 2 = Gray (Speaker out) 3 = Orange (+V return from volume unit to bass unit) 4 = Not connected 5 = Thin Red wire from thick red wire (Right input) 6 = Blue (+V power from bass unit to volume unit) 7 = Black (GND - if socket removed, solder 3 socket shield holes to each other or solder black wire directly leftmost hole) 8 = Not connected 9 = Shield copper from thick red wire
Shield copper from thick wire : Solder to GND or Left unconnected
have you tried to find out where on that same road it always goes off? could either be a new hidden camera or some other device recently installed utilising the same frequency as ka transmitting in that area. had same prob with my v1 always goes off in one part of the country road. even got out of car to investigate but found nothing that appears obvious.
I am commenting on things are here in the u/k not u/s which is not the same but i hope this is of some help.......From the wall black and white ,this is a switch wire which is on or off, i would link this to white to white , black to black or black to red with the rest left unconnected,,,,,Check to see if you have fitting instructions indicating what wire goes where....Good luck

That may be because he does not have his radar unit activated. Radar units work by sending out a microwave signal. It bounces off your car and back to the unit. It then calculates the whole distance over time thing and figures out your speed...it's more complicated than that, but I don't feel like giving a class...and I'm not a real genius anyway when it comes to physics and whatever other -ics are involved with the science of radar. Point is...radar units have a hold function..kinda like turning that microwave beam on and off...when the officer has the radar on "hold" there is no beam coming out..which means, there is nothing for your radar detector to detect. When he takes it off hold to clock your speed, the magic beam shoots out, bounces off your car, and returns to the unit..then tells the officer your speed...by the time your radar detector actually lets you know you're being clocked, Mr. Officer is already turning around to come pull you over. Hence the reason radar detectors are a waste of money...but then again, there are plenty of cops that ride around with the the sending out a signal all day and never actually put it on hold...if a cop is using the radar properly, the radar detector in your car will not help you...but, not everyone does what they are supposed to do, so therefore, it may save you from one or two tickets. Now, the reason it doesn't alert you when the police are right in front of you is because either the police in front of you; A)do not have a radar, B)do not have their radar on, C)they have it on "hold" and are not transmitting a signal, or D)your radar detector is broken and you need to get it fixed or replaced.
