Renault "Tuner List" Head Unit/CD changer hacking - Controls - Page 50

hi all!

i'm surely not in the correct topic but plz show some mercy on me.. i'm goin dizzy trying to cope up with all that data i read here...

questions now!

part I:i need to alter the wiring of the philips hu in my laguna (phase I, face lift) so that i can install a tuner list from a clio. the thing is that philips hu as i'm sure you may know haw a long conector with 7 (?) pins whereas the clio haw a rectangular one. trying to make the connections work and combinning cables didn't give out much, i only managed to make the remote on the steering wheel work but never had any luck with the on dash screen.

part II: i would also like to know how to "fool" my hu so that i can have an aux in for my pda to play through the car speakers.

i'm really looking forward to hearing from you..

kind regards

Hello, First of all BRAVO, this thread is fantastic.
I'm interrested by the cdc emulator based on a PIC microcontroler, (I just want to add an Aux Input to my Tuner list Unit). Could you just resum me at wich stage you are today. If i understand the hardware is done but the sofware is bugged. I'm electronician and driver of scenic car so may be i can help you, let me know if i'm right and what can i do?
I think first i need to do the hardware, did you know how can i do easly the PCB because it's dual side!

Kinds Regards

Here the answer for the remaining doubts:

F) the GP23 is a small alcaline battery of 12V that I use for programming PIC. In this circuit I use a MAx Tx driver to convert 0-5V of the LPT1 to a 0-12V signal needed by the 16F688 to enter the programming mode.
It need at least 10.5-11V on pin MCLR(pin4) to enter programming mode, and the internal voltage doubler of MAX232 give less than 10V, so I tied the V+ pin to this battery, and the doubler capacitor C1 is not needed anymore.
G) Sure the regulator 78L12 can be used insead of the battery without problem.

In normal running mode the MCLR is left open, the internall pullup provide the correct +5V level.

Hi ALE and all!
so what goes on..? I have tried to make PIC-based PBC of TLCDEMU. After making board, checking bugs I try to program PIC. It work, but summary of programming was the process of programing was incorect > listing LOGs and find something like this "002008 incorrect > read 00C001 wanted 003FFF"
So I tried to change this bug by changing in "Config memory" (winpic programmer) current item. after that I reprogrammed PIC and no bugs were found. So I connect PCB to HU but nothing was happened. No other item in Source. I think that is problem in wrong programmed PIC isn`t it?

I have Renault megane 98 with original Philips Radiosat 6010 (22DC459/62L) with 10 pin ISO conector for CD changer.

In this thread I found difference between DB+/DB- signals and standard BUS protocol. Could be problem here?

So maybe I find other problem. I have not grounded signal BUS for DB+/DB-. I will try to correct it and post result.

Thanx a lot! Supertronik

I've been looking around interent for projects like this, and this seems to be as close as I get.

My goal would be to connect a Sony Ericsson phone to be used as MP3 player and to work with handsfree.
I want the sound to automatically go throu the car radio whenever there is a sound coming out from the phone, and I want the volume controll of the car radio to be used.

I looked for schematics drawings of the car radio and I thought I had most of it figured out, until I realized I was looking at the wrong model... The radio I thought I had used TDA7318 audio chip which is a digital sound process with analog audio but uses digital controls. It has a input selector and after that an output and input (for external pre amp / eq, etc) and then volume etc and amplifier. This would be very easy to just use the "EQ throu" and just override the signal before volume controll etc...

However, I realized the radio I actually have is a 22DC279/62F (Philips Renault Tuner List) wich uses SAA708H Audio processor, which is a fully digital processor, which makes things harder.

Anyway, maybe it will work out anyway. On the chip there is a CD input and a Tape input that is not used (internal CD uses PDIF). There is also a Phone input, but only mono.

The CD input could be used for this. My "only" problem is that I'm not the very best when it comes to microprocessor programming, which makes things a bit complicated nowadays when everything is digital...

So what I need is a PIC (or similar) that has just one input. When the input is 1 the car radio will swith to CD input (and preferrably show AUX in display), and when the input is 0 the car radio will go back to where it was before.

I could use the "connects2 box", but as far as I understand I will then have to change source to "CD-Changer" whenever someone calls... I want it to automatically over ride all inputs so I don't have to press anything.

The analogue design is no problem at all for me, and I will post it here if I design it. But first I need the digital part figured out...

Can someone help me, please?

(I can send you data sheet for SA7708 if needed, I can't attach it due to file size limitations in this forum)

Thanks for a very good forum!

Do you top minds out there know if I can hack the basic (brand new radiosat update list) HU unit in my Grand Scenic so I can play MP3 CDs. You know a bit like changing your single region DVD player to multiregion via pressing a few buttons in the correct order. I can't believe the technology isn't already in it???? It does however have an auxiliary input, but I don't want to spend out if I don't have to! Any advice greatly recieved

cheers in advance Soundbored...

Hi,

Look here on post #458, you can find a pdf with all the info you need to connect the AUX input from your Update List HU. But be carefull, the input is versy sensitive and easily damaged. I suggest that you use 2 100nF condensators to protect the input.

soundbored · 03-07-2007, 05:36 PM

Thankyou for your input, so how does the 100nf condensator thing work, mini iso to left and right with inline 100nf in each?

Any thoughts on the HU already having the gubbins inside to read mp3 cds, the manual shows the same unit capable of mp3 playback. I reckon it just needs switching on!

If your manual talks about MP3 then you might be right and the thing just needs to be switched on. I could not find anything about MP3 in my manual so it appears to me that you have a different Update List type. I posted a picture in the beginning of this thread where the type is shown, you can check this if you want. If you want to give it a try, a simple drawing is attached on how to connect the 100nF condensers.

Hi everybody,

I read my way through the thread and the Sourceforge page. So I gather that to date, nobody has developed a working solution for the older Renault/ Philips head units, right? Pin out I found, but no protocol description. anywhere on the web, actually.

What protocol do the Tuner/ update list models use? Is that wildly different?
Any users who have had a shot at the Renault Radiosat 60x0/ D2B with some success?

I just got a Megane with a D2B unit and no cd changer.
I'm an E.E. myself, so if someone can tell me what the HU/ changer say to each other, I can build the rest. Or if anyone is based in the UK and has both HU and changer, I can come by with a 'scope and log it myself.

Buying a changer off ebay is too expensive (because I want the aux port, not a cd changer), might as well get a new radio w/ aux in.

Thanks for your advice!

Right. Only newer Tuner List models work for sure.

Not that I know of, unfortunately. As for the difference, I really have no idea.

I think it's the only way to know for sure, indeed. There are many people who have expressed interest in such a solution, but to date nobody has been able to reverse engineer the way those older CDCs work.
As for cheap second-hand CD Changers, I was thinking maybe in wrecked cars ...

Moreover it uses the same wires as our Tuner List, so that's encouraging : compare the last page of http://www.blaupunktusa.com/NR/rdonl...5E/0/MDP01.pdf to the attached pinout of the Tuner List. I also had confirmation by bistie on planeterenault.com forums that once the levels are adapted (5V TTL to 12V RS232) the protocol is compatible with a PC serial port.

Hi Vicne.. are you thereby suggesting that the protocol used by blaupunkt and by the OE renault equipment is the same, or are you merely saying, that they are both async protocols???

(im currently working on a project to fool my blaupunkt hu, which incidentally is mounted in a renault :-)

pcp · 03-26-2007, 11:58 AM

Thanks for the info. I'll try and see what I can find out. Will post if I make progress.

If anyone is interested in this and has a D2B / Radiosat 60x0 together with a CD changer, please get in touch with me!

I'm only speculating. To be clear, I have *no* idea. I just noticed some similarities...

hooverphonique · 03-29-2007, 11:18 AM

this is slightly off-topic, but since someone mentioned it in this thread already, i'll ask anyway..

does anyone here have a schematic over the renault stalk remote control? the switches are connected in a matrix somehow, but i can't seem to get the right configuration when measuring..

the car is a renault 19 btw.. the stalk rc has 4 buttons and a wheel on it..

hooverphonique · 03-30-2007, 04:54 AM

nm.. it works now... colors are the individual wires at the connector and S5 is the wheel (works like a rotary encoder, one switch closed at a time)
