Specialized Interface Modules for Your Vehicle...

Mid City Engineering specializes in designing, building, testing, and installing interface products for your Mercedes Vehicle. As vehicle electronics become more complex and computerized it becomes more difficult to integrate certain devices into the vehicle. Our interface products provide solutions to previously unsolvable problems such as our innovative patent-pending Distronic Radar Interface Module. All of our interface products undergo an extensive design and testing phase including thermal, vibration, shock, and other environmental tests. In addition, all of our devices are individually tested to insure that you receive a product that meets that highest standards. We also provide full engineering services if you need a custom module as well as qualified reference designs.

2009 SL550 Video-In-Motion and Backup Camera Kit Front Video Interface / Rear Seat Entertainment Steering Wheel Controller for 2005-2008 ML/GL/R Class One of the most popular accessories for the Mercedes SUV are the Vizualogic DVD Rear Seat Entertainment system. The Vizualogic kit adds a set of fully functional 7" High Resolution LCD monitors with DVD players built right into the vehicle headrests. Until now the only problem has been controlling the DVD system from the front seat which required stopping the vehicle and physically standing behind the monitors with the remote control. Now with the VIDM01 interface you can switch the rear seat DVD view to the front LCD on any rear camera enabled command using the steering wheel controls. When finished the screen can be returned to normal in the same manner. In addition the VIDM01R interface adds the ability to control all DVD functions using the existing steering wheel controls. When Rear Video Mode is selected the rear DVD video appears on the front LCD and the steering wheel controls are switched from controlling the normal audio functions to controlling the DVD video functions. The VIDM01R allows menu selection (Up,Down,Left,Right, and Enter), track selection, system power, play and pause.

K40221 Distronic Interface for K40 Calibre Radar Detectors
The K40221 interface module works by utilizing the vehicle CAN network to both send and receive data that allows the K40 Calibre radar detector to function while still maintaining usage of the parking sensors and Distronic features. The Distronic Plus system functions using several K-Band radar distance measurement units to allow the vehicle to sense when other vehicles or obstructions are nearby. Additionally the same radar units are used for the Park-Assist feature that provides proximity warning when parking and backing up. The K40221 Interface functions by selectively enabling and disabling the K40 detector as well as the Distronic sensors at different times to allow both to work in conjunction with each other. Additionally the K40221 module provides a display of warnings on the instrument cluster when the K40 unit has an alert event eliminating the need to cut or drill warning LED's into the vehicle.
