Sat Nav B9004 Replacing 53831

September 21, 2014

I have recently bought a B9004 sat Nav unit. I have installed this and made the relevant modifications. I am struggling with the microphone connections. There is an 8 pin connector which was installed on the back of the 53831 unit. I have 'belled' the wirs out back to the microphone located in the roof consule and indentified that there are three wires, red, black and white. These correspond to three of the wires in the 8 pin connector but there are another two wires on the 8 pin plug (violet and white/black).

Does any one know how these should be connected up on the 24 pin adapter. Do I need all five or just a combination?

I have attached a picture of the connector in question.

Your help is appreciated

I realized this operation on my RAV 4, 2011. You have to purchase the 24-pin connector, reference (90980-12404). Remove delicately without damaging the 5-pin from the connector. Connect the pins as follows: Yellow (sensor) 5, Black (macc) 17, white-black (SGND) 18, White (mic +) 19, red (mic -) 20. Do not forget to also purchase the connector E57 fitted with 3 cables, but I do not remember the reference. Using the installation instructions TNS 510, connect green (REV) cable as shown. Green purple cable (speed) is connects to the purple cable connector 20-pin E56. Buy also an adaptator for FM connector (ebay). Don't forget to connect also the cable (antenna amplifier) on ACC +, for example 3 on 10 pin connector E52. you can't find the detail of b9004 connectors here : http://www.toyotaownersclub.com/forums/topic/125437-b9004-microphone-and-connectors/#
