Well, good guess. I wouldn't have believed it was the case. Now I wonder what the Connects2 emulates. Maybe just having the time changing (no matter to which value) is sufficient...
Note that with the full [Emulator + RRPlugin + RR + Winamp] combination, time changes too as it is taken from Winamp...

Only problem was that after I switched the HU off and back on again the sound stayed off.

And what operation do you have to do to enable it again ?

Now the only thing I need is time .... does anybody now where to find some ...

I've run out of mine, sorry

http://www.connects2.com/forum/b.asp?m=2758 suggests that the VRNX001 "Tuner List" interface is incompatible with Update List HUs.

EDIT: Apparently they have solved the compatibility issues, as the interface is now called "CTVRNX001" and it comes with both TL and UL support.

Great Project, thanks, keep on the good job.

Anyone working on Rockbox (http://www.rockbox.org/) interface with HU ?

I planning on doing a pic based interface between HU and Archos Jukebox (could work with Ipod, IRiver ?).

The guys from rockbox explain how to do hardware modification on the Archos to add a serial port. The pic would convert HU remote order to rockbox protocol.

Not that I know of. Nice project btw...

That's interesting indeed. You might even try to directly emulate the protocol from the Archos and just adapt levels... Well, I admit I'm not familiar with the programming of devices such as Archos...

Don't forget to take care of the sound issue. I know some models have a SPDIF output while some others don't. If you have to do both the hardware for the emulator and for Analog > SPDIF conversion, plus Archos modification, plus connectors, and such, it might end up more expensive than a Connects2.

Well, you'd just miss the fun of course

If anyone with an Update List can borrow a CTVRNX001, spying on it would be a huge plus obviously. Without that or an actual CDC, it'll be trial and error...

Hi all,
here after working with some problem due to the baudrate (using internal osc at 8Mhz perhaps isn't enougth stable) when receiving command from HU, i solved choosing 50 instead of 51 for SPBRG register.
here is the latest release 1.3.
New functionality include interrupt rx, received command que (up to 16 cmd) management of all HU-cmd, and auto-increasing time in play frame.
Open problem:
- The volume action +- doesn't show in the display. i don't know if the SPDIF input is enabled, becouse till now i haven't a spdif source.
- I reached cc5x limit of 1kbyte of code. perhaps i will move to BOOSTC compiler, free up to 2Kbyte.

bye
Ale

If the Tuner List HU reacts the same as my Update List unit I have to disappoint you, when volume up/down is not shown on the HU display when changing the volume, SPDIF is NOT enabled. Perhaps Vicne can confirm/deny this?

I don't have the definite answer, but my bet would be that no volume change means no spdif output indeed... Maybe you can do the following test :
1) Listen to the radio at volume 5 or 10
2) Switch to CDC Emulator
3) Press and hold "Volume -"
4) Switch back to tuner

If volume is still at 5 or 10 (which I guess it would be), it means the change hasn't been taken into account so most probably it means CDC was not actually to be heared...

BTW, maybe you have a SPDIF output to test : just look carefully at the back of your CD/DVD ROM drives : http://www.hardwaresecrets.com/article/82 (didn't test it this way myself though as I have both an Epia and a SB Live Platinium...)

Hope it helps...

Can someone give me a shematic to connect a Tuner List radio to a mp3
player? Thanks

In short... there isn't.
With our current knowledge, we could probably build one, but it would be roughly as expensive as the one made by connects2.com ...

For such a connection, 3 distinct functions would be needed :
1) Hardware interface for level adaptation of control wires
2) Software emulator to fake a CD Changer
3) Analog to Digital conversion of input sound

The current status is :
- for 1, we have a solution
- for 2, we have a solution with a PC and are working on a solution with a microcontroller
- for 3, we haven't worked on it yet.

So unfortunately, unless your mp3 player has a digital (SPDIF) output, we can't give you an out-of-the-box solution yet.

here last release 1.4 with cc5x. Fixed pause & stop reply in cmd_list table. Not all HU cmd are decoded in this release due to compiler 1K limit.

I moved to boostC compiler. The final release for this one is 1.7 - Now all work fine.
The volume doesn't change if there isn't a spdif signal connected.
I have done my last test with a portable dvd player that has a spdif out.

If you use the PIC internal osc, pay attention to calibrate it with the OSCTUNE register becouse HU can't decode command with wrong baude rate. In the last version i calibrate the baude rate with an oscilloscope for 104uS x bit and choose osctune =6.
The next step is to control through the pic port, some cmos switch to interface the dvd button play,pause,next,prev.
Anybody there have a functioning prototype?
Bye

I have a Renault Clio with built in radio. Modelnumber is 22DC278/62B. (picture)

I've found this page, googling the modelnumber:
http://www.javicas.8m.com/catalog.html

Now, looking at the pinout chart at the bottom, it seems the input for this model is analog (judging from the left and right inputs, digital would be left and right into one pin). Am I correct?

If so, it should be easy to connect any (normal) analog audio signal, providing the radio can be fooled into thinking a CD changer is connected, right?

Ultimately, i'd like to connect my PocketPC/Phone to the car radio and play MP3's over it, as well as using the radio as "car-kit".

Well, indeed, it looks like it. The rule of thumb for renault is "cars made before 2000 have a analog HU - cars of 2000 and later have a digital HU".

In theory, yes. Although, the emulators we talk about here are specific to a certain version of the protocol, and we already observed different behaviours even between digital models (Tuner List vs Update List).
I have no idea if the control protocol has changed between your model and more recent ones, and I guess the only way to know will be to test... remembering the disclaimer in post #1 of course...

Please keep us informed of your tests and results.
Best regards,

Mine is a 22DC278/62H. I can't clearly tell from your picture, but if it has the words "Tuner List" on the front panel, it does not have an analog input.

Ah yes, I remember the URL. My understanding of the Spanish language is next to zero, but I am quite sure that the purpose of the RCA "hack" is to allow for an external power amplifier to be connected, e.g. to drive an extra subwoofer. In other words: the points marked are line outputs, not inputs.

The guy's description of the blue 8-pin mini-ISO does not apply to the 22DC278, but it belongs to earlier HUs which did have analog inputs. The proper pinout of your (and mine) mini-ISO is shown here (pins C13..C20).

www.connects2.com offers several ready-made interfaces you might want to look into.

Putput, Thanks for the attachment which shows how to attach an audio device to the AUX input of an Update List radio. (I want to attach the audio output of either my Tomtom 910 or my iPod, bot of which have a standard 3.5mm jack output), but I cannot find anyone who produces such a lead or who can even sell me the (green) mini ISO. Does anyone know where I can get hold of these and, when if I can only get the mini ISO separately, is it easy to connect to a lead? Thanks
