    Mmmh, that's strange. Can you make sure you don't have the LogicalPlugin still active ? This plugin changes the values of the track number on its own, and the RRPlugin also changes them, so they may overwrite each one's values. Normally, the configuration I suggest now is disable all plugins except RRPlugin. You can also leave the GUIPlugin activated if you like to have feedback, but it only slows down the startup...
    I admit I still haven't tested with more than 12 or 13 tracks in the playlist... I am building a hardware interface these nights to be able to use the actual car PC and not the hybrid setup I had until now (I currently tested with serial port from desktop PC and SPDIF from carPC).
    Tell me if it still happens with only RRPlugin, ok ?
    Hi Vicne,
    I've check the plugin config, I've activate only RR plugin and deactive the Guiplugin, the problem is still present in a track list whit more songs, after 16 track the display indicate 10 then 17.

    bye.

    OK. I'll have a look.
    Among other things, I'm currently rebuilding the definitive hardware so I cannot test anything right now. Hopefully tomorrow.
    10 instead of 17 after 16 makes me think of a BCD/hex problem maybe, or it could also be that the HU tries to anticipate the next track's number as soon as you press the button, and it "guesses wrong" (because of fake data it was given on startup maybe).
    It will be much easier to diagnose once my setup is complete.
    Thanks for the bug report

    Rosetta stone

    I rewired the circuit in spy mode for a last time to perform a few tests I had forgotten, and I formated the results at the end of the rosetta_stone.xls document - attached.
    To avoid clash between sessions, I slipped the new sessions by adding 1000 seconds to the capture time, so you'll find new data at 2000, 3000, 4000 and 5000 seconds.
    I also removed the second sheet containing the protocol decoding in itself. Please refer to the following page on the SourceForge site for up-to-date version - just updated btw.

    One of the tests I performed (included in the new rosetta stone above) is "what does the HU send upon startup when it was turned off in random mode" ? (compare sequences starting at time 2015,00 and 2060,00 in the file)
    Well, the conclusion is that in my case, it sends nothing more than in "non-random" more. Only the CDC sends the information about the random status. Moreover, the HU doesn't send a "NEXT". That conforms to its usual behaviour : upon HU restart, the CD starts in the exact state it was upon shutdown, that is same CD, same track, same playing time.

    So I don't know what is different with your setup...

    I don't know either, probably the startup sequence is different since I don't try to completely emulate the cdc.

    I send:

    Code:
      def startPacket(self):
         """Tries to send the initial packet"""
         time.sleep(0.5)
         self.flushInput()
         self._sendsequence=0
         self._recsequence=0
         if self.sendPacket('\x11\x60\x06'):
              self.sendPacket('\x25\x03')
              self.sendPacket('\x26\x05\x01\xFC\xFC')
              self.sendPacket('\x25\x03')
              if self.sendPacket('\x20\x01\x03\x09\x05\x01'):
                  return True
         return False
    nothing more and nothing less, then I enter a loop where I send

    Code:
      def fakePlaying(self):
         """Sends a fake I'm playing packet"""
         return self.sendPacket('\x47%s\0x01\0x00\x00\x01\x00\x00\x00\x00\x00' % bcd(self._track))
    The HU will send "random on"+"next track" if it was in random mode.

    Hi

    I hope this isn't considered too off topic for this thread, I apologise profusely if it is but...

    I've got a VRNX001 for my Clio Tuner List HU, connected the cable and tested, all worked fine...

    Finished up the installation and then it didn't work anymore, so I got a replacement and all replacement cables too and this one isn't recognised by the HU at all, but the first one was at first...

    Any suggestions, can the HU be reset?, if so how? The cables are so short behind it I can't get them out!

    It's driving me crazy now , I don't know of any other options for using my iPod in the car only rubbish FM transmitters.

    Please help!!!

    The plot thickens...

    I tried the unit today on a friend 2005 Update List HU and it worked perfectly, but still not on mine.

    I unplugged the power but it doesn't appear to have reset the HU as the radio saved stations are still there as are my bass/treble settings.

    I have a 182 so have the Cabasse version of the stereo which I belive is more powerful than a standard HU, and replacement Renault HU's are verrry expensive, but I don't want to have to buy another as it appears to work OK.

    I believe the stereo is out of warranty after the first year is this true? My car will be 2 in May dammit!

    I'm totally stumped and peed off now!

    Hi,

    if you are able, try to disarm the chassis of your HU, maybe some short circuit have 'cut off' some wire around the 13/14 pin.

    let me know.

    bye
    peppe
    p.s. I have had the some problem , but lucky for me the wire connected to the pin 13 has worked like fusible.

    Could you explain a bit clearer, or do a diagram so I can see what to do...

    You must forgive me but I'm a bit new to all this

    Which plug/socket is the pin on?, the HU CDC socket? or the Connects 2 plug that goes into the CDC socket? and which pin is 13/14?

    Do you mean there could be a problem within the HU itself?

    Sorry to be a pain!

    I appreacite the help very much!

    Hi,

    can you move your discussion in other thread you are too off-topic.


    thanks
