MIT019 MULTI-MEDIA TESTER FUNCTIONALITY

The MIT019 Multi-Media Test kit was developed to help diagnose customer concerns with features of the Multi-Media systems in their vehicles. The purpose of this tool is to simulate the following:

Using this tester will determine if the cause of concern is related to a vehicle system concern or the customer`s device being used.

The MIT019 can be used to perform 7 different tests of specific operations:

  1. Operation of the AUX port

  2.  
  3. Operation of the USB port for both power and Audio input concerns

  4.  
  5. Bluetooth phone pairing

  6.  
  7. Bluetooth hands free calling (send & receive) phone book push test

  8.  
  9. Bluetooth streaming audio

  10.  
  11. Bluetooth SMS messaging – send

  12.  
  13. Bluetooth SMS messaging – receive

  14.  


NOTE: When testing functions of the audio/media system, it is important to verify whether or not the vehicle is equipped with an internal or external Hands Free Module. In some cases the external Hands Free Module controls the operation of the external AUX and USB ports along with the Uconnect functions.

It is important to determine what system features are supported by the audio system in the customer’s vehicle and device. For information on the operation and supported features of the vehicle’s media system, refer to the flowing websites:

Vehicle websites available to customers and dealership personnel:

Vehicle information support websites for dealership personnel only:

The MIT019 was designed to test the following Radio/Multi-Media systems:

2. AUXILIARY INPUT JACK TEST




NOTE:

This test is designed to validate the ability of the Audio/Media system to play audio from a customer’s device that has been connected to the AUX port on the radio or externally through a UCI (Universal Customer Interface / Multi-Media) port.


NOTE:

The AUX port cannot supply power to a connected device.

1. Connect the USB and Auxiliary Cable into the vehicle's audio ports.
2. Verify the MIT019 is in AUX Mode.

Yes


No


3. USB INPUT/OUTPUT TEST




NOTE:

This test is designed to validate the ability of the Audio/Media system to play audio from a customer’s device that has been connected to the USB port on the radio or the external USB port (Universal Customer Interface (UCI) / Multi- Media port). By connecting the MIT019 to the USB ports it will also determine if the USB port can provide power to a connected device.

1. Connect the USB Cable into the vehicle’s USB port.
2. Place the MIT019 into USB Mode.
3. Using the vehicle controls, place the audio system into USB Mode. (Audio system may automatically enter into USB Mode.)


Does the Radio play audio from the MIT019?

Yes


No



NOTE:

The radio and external USB ports can only supply 5 volts at 500 mAs. Check to see what the customer’s device requires for operation or charging. Some vehicles are equipped with a standalone USB charging port that can supply 5 volts at 1.5 amps. For more information on system operation and supported features see the vehicle supporting website “For Owners Page” or the http://www.driveuconnect.com.
