Hello guys,

 

 

First off all I would like to say that I have read a lot about this subject that I'm creating right now.

Another point... yes this subject is very present at all Skoda and VW forums however I have a particular problem. (so keep it reading please  )

 

 

PROBLEM:

Directly to my problem I have no sound from speakers in my new RNS 315 and no steering wheel functions but I have Navigation, Bluetooth, Mic, GPS working perfect!

 

 

 

HISTORY:

After 1 year and half with my Octavia I decided to replace my Audience with a second hand Amundsen.

The main goal was to remove the original Big Cellphone Holder and get a singular unit that had Navigation, Hands Free and Media player thru Bluetooth and Line in.

 

I bought an one year old RNS 315 and I saw it working in the Skoda Octavia facelift (mk3) from the seller.

The job of installing everything took a little bit more time then I though (some of you are smiling right now I can feel it  ) but I had the help from the RNS 315 seller, that was very kind and helpful. (He have installed 2 in the past)

 

So, we disassembled the cellphone holder, installed RNS 315 + New Gateway + Bluetooth + Antenna GPS and connected all the cables correctly.

 

At this point we entered the pin code and the RNS started... but no sound from it as was expected.

After that we proceeded to the activation with the vagcom 12.12 cable and software, from RNS seller. (I was very new in this environment!! )

 

It's important to say that we check listed everything from the original Gateway/CANBUS to the new one.

 

 

We followed what we can read in all the forums like this one:

 

http://www.my-gti.com/1411/volkswagen-rns-510-coding-when-installing-with-a-factory-amplifier

 

However and unfortunately the last step is empty.. no option to select ou change.

At Byte 5 when I select the Bit 00 there are nothing, off course I tried to found it in other Bit with no success.

 

 

I am suspecting that I have a little difference from the other Retrofit owners I founded in forums, I have an original amplifier and 12 speakers (I think).

So, right now I think that (maybe) the main obstacle between RNS and Speakers since that RNS has it self amplifier I need to shut it off to used the car amplifier.

At the Vag software when I select Navigation it play a 2 or 3 second of sound so I am sure that all the connections are ok.

 

 

 

 

POINT OF SITUATION:

 

Not Working:

- sound from speakers

- steering wheel commands

- parking sensors and AC controls information in RNS

 

 

Working:

- GPS Antenna

- Mic

- Navigation

- Radio

- Bluetooth

- SD Card reader

 

 

 

I will be here to answer your questions or at least to try and I will reunite more information if you need to clarify other points.

I hope to find some answers from you guys, I know that there are a lot of experts here

I would like to say that I registered in this forum to be part of it and not only to solve this situation.  :coffee:

 

Thank you for reading this boring and long first topic,

João.

 

The usual fault with no sound is that the unit is coded for a "Sound System" and the car doesn't have the sound system installed, or the car has "Sound System" installed and the unit is not coded for it.

 

Look for this (or similar) setting in VCDS...

 

 

and change the setting accordingly. Like if "Skoda Sound System" isn't selected then select it.

Edit: Depending on the age of your car you might not get the steering wheel controls and parking sensors showing in the display. This is due to the communication settings between the car and the unit, and incompatible control units. For the steering wheel controls, if your car uses DDP communication then the head unit uses BAP communication, and they don't talk to each other.

Another problem that I didn't mentioned it's about no "skoda options", for exemple no "Skoda Sound System" but only VW or Dynaudio.

However I tried every option in that Byte and Bit and no results from that.

 

The newest CANBUS is a second hand one, from a VW.  I think so...

At this point I'm not sure if this CAN is the indicated for my octavia.

The seller said me that the lastest CAN the better for me. That made sense for me after his explanation.

 

Other point:

I heard (about RNS 510) that after made any change from software the user should reset it, I'm not sure about that but if it's true... How do I reset RNS 315 since that button combination doesn't work?

My car is an Octavia Break 2005/06 and it had all that options from factory:

 

- steering wheel functions (now do not even have the button lights on)

- parking sensors and AC changes in the Audience screen.

 

 

About DDP and BAP communications, how can I clarify that?

 

 

 

 

Thanks,

João.

I can clarify the DDP/BAP thing for you. Your car uses DDP communication, and the RNS315 uses BAP. So they're never going to talk to each other correctly. Steering wheel buttons, and aircon settings will not work.

 

There's no reset function on the RNS315. Just power down and power up again, and it'll accept any changes you made.

 

One other think, you should perhaps try coding with the latest version of VCDS rather than the old version (cracked software and cheap cable) which was used according to your first post. Genuine VCDS versions update themselves and have support for all the latest revisions of controllers and coding helpers.

Thanks for that clarified answer!

 

When you say "they're never going to talk to each other correctly"

You mean never never... or never without a correct coding?

 

About VCDS you are right I used an old version and I think a cracked software and cheap cable since wasn't mine I can´t ensure.

 

 

Actually my Octavia is at electronic workshop since Thursday with a guy that was told me that is an expert in automotive electronic field.

Even so there wasn´t any evolution so far...

Never ever. You can't make the RNS315 talk via DDP, and you can't make the car talk via BAP. The other possible solution is to install a Columbus system which has switchable BAP/DDP settings, but even then you wouldn't get the aircon settings working onscreen without an upgraded controller (unsure what's needed here though). And you'd not get a Columbus with Bluetooth as they don't have it, but the benefit is you don't have to live with the crappy small screen of the RNS315 and the lack of other functions such as internal hard drive for music storage, simple maps updates, dvd drive instead of cd drive which the Columbus provides.

I didn´t know that difference of communication capabilities between 510 and 315, I thought the difference was only screen size, harddrive, etc.

 

Actually losing AC information in RNS's LCD doesn't bore me... in the middle of this situation is the least.

 

 

About bluetooth no problem because I already have installed the bluetooth module (is working fine), my RNS 315 doens´t have bluetooth incorporated.

 

 

About the Gateway with no Skoda options or even some other options do you have any idea why's happening or have any solution/action to try?

It's possible to "upgrade it"?

I don't know about the possibility of upgrading the gateway, some can be updated but it's main dealer only and cheaper to buy the correct one really. Also, I don't know why you're missing some options in coding, unless it's an issue with the VCDS version or the gateway itself.

I will check the prices from the dealer in the mean while there are any problem using a VW Canbus in a Skoda?

 

How can I clean/erase all info from the CAN in order to start from the scratch?

I don't think there's any such thing as starting again with the gateway. It needs the correct coding for your vehicle, and any new coding overwrites the previous coding as far as I'm aware. Nothing to be gained by trying to clean all the settings and start from scratch, it just needs to be correct. I dunno what your old gateway was, or what the new one is, but the same part number is used in VW/Skoda/SEAT so it's not really a VW gateway as such.

I think you are right about VW or Skoda Gateway, they are the same. 

So, the worst part is that I don't know why some options doesn't appear in some Bites and Bits.

 

I attached some imagens to show you both Gateway, old and "new" and the RNS serial.

 

New

 

Old

 

 

RNS 315

 

 

 

 

 

About coding I remmember that I tried to overight with a coding that I saw some in the internet from a similiar case and VCDS didn´t let me change.

The software just let us change if the code is correct? I dont have that idea, but in that case what is the best way to know correct coding?

 

 

 

 

 

Well, your gateway would appear to be correct. I'm unsure why you're not getting the correct long coding application, but I can only suggest that it's the older version VCDS you're using.

I thought exactly that but it seems they are still having the same problem at the workshop.

Turning OFF 47. Navigation module and then it appears ON again for example...

I can say that they have professional and original new machines/computers from VW and other brands.

 

For me the most strange fact is that every feature (from RNS) that do not came from factory is working fine, like GPS, Navigation, Bluetooth and the Sound doesn't work.

Yesterday the workshop concluded exactly what have you said about communications from car and rns 315.

so, I decided to sell the RNS 315 and after that I going to buy the RNS 510 in order to get everything working perfectly.

 

 Any Skoda RNS 510 works fine or there are some edition that I should avoid?

The Columbus (Skoda RNS510) version shouldn't make any difference. You've updated the Canbus Gateway, so there's no need to worry abut the battery drain. You might need a firmware "fix" to make the steering wheel and maxidot work correctly. In all honesty, the newer the better as far as Columbus is concerned, but I'd certainly avoid anything made before 2009 - 2010 as the hardware from those units is prone to sudden failure.

Uhm ok.

 

RNS firmware fix right?

 

Actually the maxidot is working fine no problem with it.

It's the version without navigation arrows and that new stuff, maybe thats why its working fine.

 

How do I know the release date of an RNS? Serial numbers, code or they have the date right somewhere aroung its body?

They all have the date on the label on the top. The label also has software and hardware details as well.

Ok, thanks again.

There is possibly one thing you can do to make the rns315 and older steering wheel and maxidot communicate and that's via a Polar BT box or Polar FIS. I have a pre FL Octavia that works with a newer BT module that is BAP only showing in the maxidot and answerable via the MFSW. This changes the BAP setting of BT module so it can be interpreted by DDP so it might work similarly with the rns315. Alex (Rainbowfire) is the one to ask as he had an rns315 and the FIS at one point in his pre FL.

Hi adamal, thanks for your replay.

 

I didn't know that box exist and that sounds good but it's very pricey, around 275€.

My main goal now is sell the RNS 315 and thereafter buy the RNS 510.

However, I will keep this option on the table in case of don't sell it.

 

Thanks for that new information.

 

Cheers,

João.

I asked Polar about this when I had my 315 and they said their unit is not designed to do DAP/DDP translation for MFSW.

Hi guys,

 

I'm very happy and I want to thanks your replies.

This Weekend I will try a 510 from a friend of my to see if it works easly and everything it's ok.

 

After all your replies I decided to re-install the old unit (Audience) but three days after that I ran out of batery.

 

Short story:

I drove to Ikea been there 2 hours and when I tried to turn the car ON it was totally dead.

I connected the cables from other car and it turned on, then I drove during 1 hour to charge the batery.

Next day the batery was dead... I bought a Varta and replaced the old one then everything worked fine.

 

So... I just wan't to know why my batery ran out and what I need to do.

Timelife?

Something draining it?

Other reason?

 

 

CANBUS GATEWAY? (I dont think so)

I agree with Mike that I got the currect CAN, if not the batery should have died with RNS 315 insted off Audience, correct?

 

GLOVE COMPARTMENT LIGHT? (I dont think so)

Another point is that the glove compartment light remains ON even if it's close, but only when the car is unlock (bad assembled, I need to assemble the gloove store again). I think that ins't enough to drain a batery, right?

 

What you say?

 

 

By the way I think I will buy a powerbooster kit or something just to check the batery level, because I need my car everysingle day and I can't run that risk again.

 

 

Thanks for your time,

João M.

Hello

 

 

Unfortunately I have tried the RNS 510 Columbus 2010 and the result was exactly the same... no sound.

There are any difference between production date?

That unit was really slow compared to the 315 form 2013... that fact was really disappointing.

Is it normal a 510 be slower than a 315?

 

 

Cheers.

Hi,

 

 

Sorry Mike, but I think you mistaken when you said "if the unit is set for premium" in both situations  Can you clarify it, please?

 

 

 

This is the difference with premium sound - if the unit is set for premium, the sound output is bypassed from the headunit itself to the amplifier under one of the front seats. If the head unit is set to premium, it will be trying to output from an amp that is not there.

 

 

 

 

I have no doubt that 510 is better then 315. 

However, even with the 510 I will lose the aircon settings but not the Steering wheel buttons, right? Or it's possible to get everything working fine with a RNS 510?

 

 

 

This weenkend I will try another 510 so this is my last oportunity to do it well, or at least to try it the best way.

So I will need some more tips from you guys, about the procedure to switch from BAP to DDP (in RNS) for example and other points that are relevant.

I am concerned about that VCDS option that should appear and it doesn't. I am not sure if with the 510 it will show or not.

 

 

 

Thanks

Mike,

 

Sorry about my bad explanation what I meant with a possible "mistake" was about the sentence not in true behind what you said.

I trully bealive in your words and I know you are right and also you have that knowledge! Just making it clear!

 

 

I will try to explain it better:

 

"This is the difference with premium sound:

 

if the unit is set for premium, the sound output is bypassed from the headunit itself to the amplifier under one of the front seats.

If the head unit is set to premium, it will be trying to output from an amp that is not there."

 

 

I think you want to say in one of this lines "If the unit is not set for premium" but you said "If the unit/head unit is set to premium" in both sentence.

Thats why it doesnt make any sense for me and I hope this time I had explained well my doubt.

 

So my Octavia has an amp under driver's seat so should I choose premium? Thats the important question

 

 

 

One more time I want to apoligize my english, I am not an expert and is difficult for me express as well as I want.

 

Thanks,

João.
