Has anyone plugged an aftermarket car DVD player into that aux input?

 

Ed

 

Yes, and nothing happens. I did manage to get a picture on it by entering the monitors diag screen and switching to AUX. But I have no idea how we'd normally go about switching to that input.

 

On the back of my B9's monitor I also have a 5 pin green connector in the top left, it isn't on the schematic so I'm kind of hoping that it is the RSE plug...

Here's how to do it on a spec.B. Set the parking brake and turn on the AUX video source. Press the INFO button below the screen to view the video. To adjust the video (contrast, size, etc.) press the button to the right of the INFO button below the screen.

 

If you want to watch video without setting the parking brake, then you have to ground a wire going into the display unit. That wire has been described as gray but it appears light blue in the picture linked below. In that picture the wire has been cut and the end of the wire leading into the black connector has been stripped of insulation. That's the end that needs to be connected to a ground.

Hmmm... When I hooked it up the parking break WAS on, and the info button did nothing... I'll play around again with it tomorrow, but have a feeling things may be different. I know the input works, I just wish I knew how to switch to it :(

subscribe. I wanna to have a boost gauge in the navi system in one of the windows

 

That's my ultimate goal - software boost and EGT gauges on the OEM NAVI screen. Haven't had time to mess with it at all.

Forget it. You would have to be able to reprogram this stuff. It's properietry so unless you're a maestro of hacking and programming and have infinite amount of time... or unless you'll get documentation with whatever compiler (prolly a cross-compiler) for that platform... no way, forget it.

 

For EGT you need a sensor, that our car does not have. Yes it could be hooked up to a computer with a proper analog-to-digital converter.

 

Boost is available in ECU and on the car's controller area network (CAN).

 

The only realisitic possiblity is to hack the monitor (screen) and hook it up to a carputer (in-car pc computer), that could display boost, egt and what not for you.

 

But then you would have to ditch the OEM navigation or figure a way to share/switch the display between the carpc and OEM nav.

ok no more drinks for me...:icon_bigg

 

Oh, well, the EGT sensor in the uppipe is pretty useless. If you want to measure EGT you need one (or more) in exhaust manifold.

Nothing is impossible. It was programmed, it can be reprogammed unless it's embedded on a PROM that can't be flashed and must be replaced - then forget it.

 

Who cares about a friggen camera?:icon_conf

I thought you were going to revamp the lame guage pack

that's in the nav menu?:icon_bigg

You're not reading or understanding my posts. That's exactly my point and mission.

Sure, in theory yes... sorry to be skeptical, but sys admin skills are not up this task. You would have to disassemble the code in the nav computer and reprogram it in assembler (I wonder what CPU that comp has). Unless you can find a cross-compiler for it, so you could embed some compiled code (for the new functionality), but then still you would have to hack in assembler to hook up the new code.

 

Besides, remember, even if in theory you could reprogram it, you may not have all the information available in the nav computer. I am not actually sure if it can pull everything form CAN/ECU, or it's just fed with fuel consumption data.

 

Anyway, I wish you good luck...

Thanks. I'm skeptical too but very curious. I think you're right. I'm a mechanical engineer (by degree) and a Sys Admin by current trade with some Assembly experience a long, long time ago. I think what's needed here is a really bright Electrical Engineer - certainly not me.

 

The NAV has got to be fed at the very least: TPS, Fuel Consumption/Pressure, Odometer/Trip, and Velocity (if not from the ECU then from GPS) in order to calculate and display the current gauges, IMHO. I'm doubtful (but hopeful) about ECU EGT and Boost information being fed there. You never know.

 

One of these days, when I'm not camping, playing soccer Dad, and commiting to all sorts of other family responsibilities (not complaining), I'll seriously investigate.

This is probably stupid but I have a question...

 

Has any tried to get into the Diagnostic menu according to the instructions? It looks like the default password is 014220.

 

It is accessed by pressing for 5 seconds or more on the top center portion of the screen.

 

They probably changed the default password, but I thought I would ask anyway.

Works for me and other Spec.B owners. There are pictures posted in this thread - screenshots.

I had to press the info button 2 times, first one gets me to the normal input, and the second press(with barking park on) is for the Video input on the back of the screen. I also found that if you do not have a video cable connected to the back it will not go to that screen.

that posting anything without pictures is useless, so here is two pictures of waht the screen looks like with video. My Camera picked up the pixels a bit, but when your watching it you can't see them. (These were taken a night, I can post day pictures once daylight hits.)

Any progress getting the stilly destination lockout while moving disabled? I popped in the DVD-ROM and it looks very much like what the Corvette folks are struggling with:

Sadly, they haven't figured it out yet. Neither have the Cadillac folks, again with a very, very similar unit.

 

http://www.cadillacforums.com/forums/cadillac-srx-forum/13242-another-nav-diagnostic-code.html

 

All of these, including the Subaru, use the Denso format. I found the 014220 code in the boot file, and there are tons of other numbers, too. The vette folks tried similar things to no avail, though.

Boot file? What boot file? Where/how? What other numbers? Where is the boot file? Please share.

On the DVD, you'll find a LOADER.KWI that some believe is firmware or bootloader. It contains strings that appear on the screen. Folks have found some limited documentation the KWI format. I'm going to attempt to get their "decoder".

 

Anyway, here are the numbers I came across. I haven't tried them all yet, just the ones that "looked" good. Folks in the other forums have done this, although I expanded my search a bit more than they. They've reported 2 other codes that work, which will be different on our system, but worth a shot.

 

Note that these will likely be different depending on what version of the software you have. I have ver 1.1 2005-2006 (which, BTW, is completely inaccurate for addresses in my county.)

In my VW/Audi days, you could reprogram the car into different modes (Europe, US, CAN, etc) and this would bypass having to click "accept" everytime the nav was started.

 

Surely something similar can be accomplished for us? Maybe for the GM guys as well if we want to be chummy.
