It`s not your fault tear down is rather incomplete. It doesn`t have complete instructions as to deconstruction for repair.

THANK YOU FOR A GOOD TRANSACTION, NICE COPY, CLEAR
;
Very Good! All the diagram are easy to read, and its complete.
;
This was an excellent source of detailed assembly information on a device which is at least 12 years old. A very lucky find, coupled with great service.
;
Excellent Service Manual and best price on the Internet. This Service Manual covers everything you could ever need including full circuit schematics, component layout diagrams, stripdown procedure and full parts list/breakdown. I needed this to carry out a modification to one of these headunits and this manual covered everything I needed. Fast delivery, processed within a few hours.

[3] Downloading Sequence
A
� Downloading the firmware to the AUDIO DSP
Downloading the firmware to the AUDIO DSP is performed in 4 sessions. 1. After reset of the AUDIO DSP is canceled, DSPCS# is set to �L.� Then transfer of the initialization program 1 starts. 2. After the transfer is completed, it is checked that DSPCS# is set to �H.� Then DSPDREQB# is set to �L.� 3. DSPCS# is set to �L.� Then transfer of the initialization program 2 starts. 4. After the transfer is completed, it is checked that DSPCS# is set to �H.� Then DSPDREQB# is set to �H.� 5. DSPCS# is set to �L� then transfer of the initial values starts. 6. After the transfer is completed, it is checked that DSPCS# is set to �H.� Then DSPDREQB# is set to �L.� 7. DSPCS# is set to �L.� Then transfer of the program for the main unit starts. 8. After the transfer is completed, it is checked that DSPCS# is set to �H.� Then DSPDREQB# is set to �H.� Downloading is completed. DSPCS# (Pin 50)
B
SPICLK (Pin 53) SPIOUT (Pin 55) DSPDREQB# (Pin 27) Approx. 110 msec Note: The above-mentioned pin numbers are those of the IC202 (SOUTH CPU). Transfer of the initialization program 1 Transfer of the initialization program 2 Transfer of the initial values Transfer of the program for the main unit
C
� Downloading the firmware to the FPGA
1. The FPGRM is set to �H.� 2. It is checked that SD2_OUT is set to �H.� 3. Transfer of the FPGA firmware starts. 4. After the transfer is completed, it is checked that DONE is set to �H.� 5. After a wait of 1 ms or more, FPGARST# is set to �H� (released). Downloading is completed. FPRGM (Pin 38) SD2_OUT (Pin 36) SPICLK (Pin 53)
D
SPIOUT (Pin 55) FDONE (Pin 37) FPGARST# (Pin 46)
Transfer of the FPGA firmware 1 ms or more
Approx. 200 msec Note: The above-mentioned pin numbers are those of the IC202 (SOUTH CPU).
