rexx Posted September 30, 2010 Share Posted September 30, 2010 Hi Everyone, A Long shot in the dark this... If there is anyone out there who owns an oscilloscope and a Z with the motorized navigation cover, please please post results of readings taken from Output signal on the "Power Cluster Lid Amp" (as listed in the technical service manual). The "Power Cluster Lid Amp" is a small box like unit located behind the 3 pods of the center console. It has an 8 pin connector and its connections are as follows: ____==____ | 1 2 3 4 | | 5 6 7 8 | ------------ Layout above is when looking at its white connector. Mirror (horizontal flip) the layout when looking at the connections on the unit. Pin1 - Ignition Pin 2 - Ground Pin 4 - Battery Pin 8 - Output Signal <-- This one! This one! Many thanks for reading, Rexx Quote Link to comment Share on other sites More sharing options...
Husky Posted September 30, 2010 Share Posted September 30, 2010 there are very few people with the motorised lid i'm afraid so you may struggle Quote Link to comment Share on other sites More sharing options...

marzman Posted September 30, 2010 Share Posted September 30, 2010 What are you trying to achieve? Asking a question like this is an absolute long shot, but if you give us an idea of what you're trying to do then perhaps someone has done it before...

rexx Posted September 30, 2010 Author Share Posted September 30, 2010 I've got a japanese nav unit and display on my bench that's currently hooked up to a logic analyzer. All signals from the nav unit seem to output correctly and I can see the display is active, all pixels are on and displaying black but the backlight is not lit. I'm wondering if the display is waiting for a "wake-up" command because the nav unit thinks the dash cover is closed. For a 2005 system the "Power Cluster Lid Amp" sends this control signal to the nav unit which in turn activates the screen maybe... Problem is I dont have that part so don't know what type or signal or waveform is required. The manual doesn't list a any reference values for it either. I actually own a 2006 UK car with nav that doesn't depend on this, but I'm just experimenting right now to see how much can be reverse engineered... Eventually I may just gut the spare nav unit and pack a Pico ITX computer with slot loading DVD drive into its shell, mount this to the passenger side rear deck and integrate this to the OEM screen, nav controls and sound system. Anyway, I'm just getting started so not much yet but here's some things of interest: - The display unit seems to have multiple signal input configurations. On its PCB, there are markings for RGB, RGB sync, horizontal sync and vertical sync, TV and DVD input lines. Some of these output pins are unused and not documented in the service manual. - The RGB sync rate is somewhere between 14.5khz - 15.5khz which suggests a CGA display so quality may not be the best. - The "RGB Area signal" as written in the manual could be video luminance signal because its marked as "Y" on the PCB Quote Link to comment Share on other sites More sharing options...
