This an amazing system I used to sell at my company, the main detection module was sent to the factory for a checkup/upgrade (I have the paperwork from Beltronics) and is ready to go, it is all ready to go for a new owner now.
The spec's are as follows:
Features
Stealth-installed Remote Detector: The Beltronics STi-R is a custom-installed digital radar, laser, and safety detector. The radar/laser receiver is designed to be installed under the hood of the vehicle, with a dash-mounted control panel, concealed LED display, and an amplified speaker that is loud enough that it can be hidden behind the dash. The system is tied together by a hideaway interface. Professional installation is highly recommended.

TotalShield Technology: The STi-R is equipped with TotalShield technology, which makes the unit 100% undetectable to any radar detector detectors. Not only is the detector immune to VG-2 radar detector detectors (RDD), it can not be detected by the newer RDD called Spectre.

Detection Capability: The STi-R includes full X, K, SuperWide Ka, and Safety Warning System radar capability, laser detection, and digital signal processing for superior range and fewer false alarms. You can program the unit to enable all bands at once or you can select one or more bands to turn off (once you have determined there are no traffic radar units using the disabled bands in your area). If Ka SuperWide is turned off, you can turn on or off each Ka segment (Ka 1 through Ka 10).

Pop Mode Detection: The STi-R includes protection against "Pop Mode" radar, a relatively new feature for radar gun manufacturers. It works by transmitting an extremely short burst, within the allocated band, to identify speeding vehicles in traffic. Once the target is identified, or "popped", the gun is then turned to its normal operating mode to provide a vehicle tracking history.

Radar/Laser Receiver: The system's Radar/Laser receiver is equipped with a dual LNA Microwave receiver, a Superheterodyne, Varactor-tuned VCO, a Scanning Frequency Discriminator, and Digital Signal Processing. For Laser detection, the unit features a quantum limited video receiver with 5 optical Laser sensors. Typically, the receiver is mounted under the bumper, or inside the front grille of the vehicle. For best performance, it should be mounted horizontally, with a clear "view" of the road. Dimensions: W=3.675", H=1.207", D=4.125"

Control Module: The STi-R's control module is designed to be mounted within easy reach of the driver's seat. It can be surface-mounted using the two-sided adhesive strip. The control module has a power-on LED, a Power button, Volume/Mute, and Sensitivity button. To program the unit, you can press the Sensitivity and the Volume/Mute buttons together. Dimensions: W=1.95", H=0.651", D=0.563"

LED Display: The STi-R's display is designed to be surface-mounted or installed in a cutout in the dash. A red lens is included to conceal the display module in the dash. The display consists of 280 individual LEDs to provide an intuitive ultra-bright display of signal strength and text messages. It will show "Highway," "AutoScan," or "City NoX", or a single letter, as its power-on indication. During an alert, the display will indicate the radar or laser band, and a precise bar graph of signal strength. Dimensions: W=1.958", H=0.656", D=0.703"

Optional Concealed Display: A single LED can be installed to alert you to radar or laser detection. To install the supplied LED, a 1/4" hole is required for the LED clip.

Amplified Speaker: The STi-R comes with an amplified speaker for the audible and voice alerts. It can be mounted in plain view, or can be mounted behind the dash or another out-of-sight location. Installation requires connecting the speaker to a switched 12V power source and ground, plus the audio signal cable needs to be plugged into the system interface. Dimensions (w/o brackets): W=2.264", H=2.274", D=2.147"

Voice Alerts: In addition to visual alerts, the unit features digital voice announcements. If you prefer, you can turn off the voice alerts and have the unit provide audible tone alerts.

AutoMute: The patented AutoMute feature will reduce the volume to a lower level after a radar encounter at the selected volume. This keeps you informed without the annoyance of a continuous full-volume alert. AutoMute can be turned off, if desired. You can silence the audio for a single specific signal by briefly pressing the Volume/Mute button on the control panel. After the radar encounter has passed, the mute will automatically reset and will alert you to the next encounter.

Brightness Modes: The STi-R has three display brightness settings, plus an Automatic Mode and Dark Mode. In the program mode, you can cycle through the Brightness Modes: Auto, Maximum, Medium, Minimum, and Dark. When Automatic is selected, the brightness is controlled by a sensor that measures the ambient light in the vehicle. In the Dark Mode, the display will be totally dark, and only audible alerts are used when the STi-R detects signals.

Programming: There are 7 user-selectable options to allow you to customize the STi-R to your own preferences. The programmable categories include Pilot (Power-on Indicator), Voice Alerts, Power-on Sequence, Signal Strength Meter, AutoMute, Brightness, and Radar/Laser Bands.

Pilot (Power-on Indicator): The Power-on indicator can be a full word ("Highway") or a single letter ("H").

Power-on Sequence: When the STi-R is first turned on, the standard power-on sequence includes a series of displays followed by a brief X-band alert. If any bands have been disabled, a double X-band alert and corresponding message will alert you that one or more bands have been turned off. If you desire a quicker power-on sequence, you can switch to "Fast Power-On" which provides only a single X-band alert if all bands are enabled, and a double X-band alert and a corresponding message if any bands have been turned off.

Signal Strength Meter: The STi-R's standard bar-graph signal strength meter only displays information on a single radar signal. If there are multiple signals present, the detector's internal computer determines which is the most important threat to show on the bar-graph meter.

Threat Display: The Threat Display option is an advanced display for experienced detector users. The Threat Display simultaneously tracks multiple radar signals and their relative signal strength. It displays what band each signal is and a numerical reading of its signal strength.

Tech Display: The Tech Display option is for experienced detector users. It displays the band and the actual numeric frequency of the radar signal being received.

Vehicle Voltage: When the vehicle's battery voltage falls below 10.5 volts or rises above 16.5 volts, the detector will give you a low voltage or high voltage warning and sound an audible alert.

City Mode Sensitivity: The detector's City Mode significantly reduces X-band sensitivity to reduce annoyance from X-band intrusion alarms and motion sensors. In addition to the Standard City Mode, you can further reduce X-band sensitivity by selecting "City Mode/Low X". If you are absolutely certain there are no X-band traffic radar units in the area, you can select "City Mode/No X" and the detector will not respond to any X-band signals.

The unit retailed for over $1000.00 and is a steal at the price I am asking. Serious inquiries only.
