Thread: Renault "Tuner List" Head Unit/CD changer hacking - Controls

I admit I have no idea if there are differences between Tuner List and Update List models. Although, it seems the same CD Changers are compatible with both I'd be surprised if they were different in that regard.

A few tests to perform, maybe :
- if you use NEXT/PREV on the stalk controls, does Winamp change track ?
- if you use PAUSE/PLAY, does Winamp follow ? Note that if SPDIF has been disabled in the HU for a reason or another, a PAUSE/PLAY cycle often re-enables it.
- do you have a means to test the SPDIF output of your SP13000, to make sure there is something actually coming out of it ? Please note that for the M10000, there is a typo in the manual that gives the video/spdif jumper settings wrong.

You're not far away, I'm sure... Good Luck

Yes, factory settings is video for all Epia's I think.
Now it'd have been fun if you had seen video on your HU :-)

Just to rule this out, do you by chance have another device with a SPDIF output (DVD player) to connect to the HU or or one with a SPDIF input (receiver or home theater amplifier) to connect to your Epia...
I'm almost sure the problem isn't there now, but you never know.

A question, when I try to change the volume in CDC mode, and playing frames are sent to the HU nothing happens, shouldn't the display show the volume level when changing? It does this in tuner, AUX and CD mode but not in CDC mode, is this normal?

No it isn't. Volume changes should be shown on HU display indeed...

And the volume level isn't changed so I assume that the audio input (SPDIF) is not yet activated. I also remember that the first version of the Connects2 adapter was not compatible with Update List models, their new version works on both types (Tuner and Update) but this was not always so.

I didn't know that.
Obviously, it means there *is* a difference between TL and UL head units :-(

Perhaps the Update List model doesn't accept sending 00 as playing info in each frame? Vicne, is there a simple way to change your program so that it sends real playing info?

Well, I don't want to disappoint you but there are many reasons the SPDIF could be de-activated. I can see a few options to try :
1) to answer your question, yes, there a simple way for the program to send real playing info : just use the LogicalPlugin : see http://tlcdcemu.sourceforge.net/plugins.html
Time is incremented every second, CDs are declared of 20 tracks x 3 minutes, and tracks change automatically. I advise you to activate only LogicalPlugin and GUIPlugin instead of the RoadRunner one (there might be conflict if you activate both).
2) Before you change that, did you try PLAY/PAUSE/NEXT/PREV and numbered buttons ? Even if you don't have RR, try with the GUIPlugin... Are the commands sent ? Doesn't a PAUSE/PLAY activate SPDIF ?
3) You might have more luck with Pippolippi's emulator. By luck, we took different approaches (full vs simplest) so it could well work
4) If you want (me) to debug further, it would be interesting to have the full log of the startup sequence. To do that, just append '>tlcdcemu.log 2>tlcdcemu.err' to the first line of TLCDCEmu.bat, so that it looks like :

Code:

java -cp ./classes;./lib/RXTXcomm.jar org.tlcdcemu.main.TLCDCEmu >tlcdcemu.log 2>tlcdcemu.err

then run the program with maximum debug Level (6) for a full session and then post the two log files...

Note that there is a non-zero probability that we won't be able to go further without spying on a UL Tuner list connected to an actual CDC or a Connects2...

Let's cross the fingers.
