9WZ bluetooth/ media issues

[Domatron]

Hi All

I installed a 9WZ unit into my R36 wagon a few weeks back. Below is the link to the thread. Thanks to rjt86 for his help.

I have got the system (mostly?) setup and have some annoyances. Hopefully someone can help.

1. When I get a SMS or email notification the audio is muted for a few seconds. I have tried changing a few settings on the RNS and the MFD. The only thing that I have found to work is disconnecting the phone from media in the MFD bluetooth setup. I have an iphone 6 plus while my wife has a standard iphone 6 and her phone doesn't do this! I have changed a setting in the MFD in the section telephone>audio to "calls only". Before it was set to "always" and when it was the sound would mute when the phone was connecting. Now it only mutes for notifications.

2. When playing music through bluetooth media the sound only comes out the front 2 speakers as if in a phone call. None of the other speakers work. The tone button on the RNS seems to be disabled when bluetooth is playing so I cant change the balance etc. When the volume is changed the volume bar is green and says "telephone".

I have tried changing all the logical settings in the RNS and MFD as well as VCDS but nothing seems to have worked. Some details that I think may be relevent:
R36 wagon MY09
White MFD
RNS510 part # 1T0035680L firmware 5238
BT part # 5N0 035 730 D

Any help is welcome.

Thanks

Hi All

I am still having issues with #2 above. Number 1 has been resolved. I have disabled media connection via buetooth on my phone for this bluetooth pair which got rid of the notifications but means that I can't play music over bluetooth. I have to use the AUX cable which is less than ideal.

It seems that I am not the only person to have this issue. Below is a link to another forum where the poster describes the same problems, except they are using an RCD head unit and Fiscon bluetooth. It appears their problem was eventually resolved by a firmware update.

View topic - Fiscon Bluetooth - Sound Quality • SCIROCCO FORUMS, friendly community, info, news & advice.

And here is a link to a VW site where they describe how to setup the bluetooth connection. In this walkthrough the 2 speaker issue is described as normal!!! But if you watch the video towards the end there is footnote that says this was not a problem on later models.

Connect or pair your mobile via Bluetooth to your Volkswagen

Is it as simple as doing a firmware update on my 9WZ? Is that possible? If so how would you do it?

Any help would be great!

Thanks

Firmware updates are possible but only with ODIS.
It possible that it's a firmware issue but that 9zz unit is from 2010.
What software does it have currently?

Hi mate
Sorry I thought I had already replied. Below is screen grab I took of the HW/SW info on VCDS

Ok that unit is a Novero HT4 'UHV Premium' module.
Its from 2010.
I can't find a firmware update for it that looks compatible.
It was superceded by the Novero HT5 based unit with part number 3C8-035-730-E which has wifi support.
This has PR code of 9IC/9W4/9ZG/9ZU/9ZZ

I would test a newer unit.
If it works then you have a solution - upgrade to a newer unit.
If it doesn't resolve your issue then you have a wiring issue.

Thanks Kamold. I'll give that a go.

You need Odis engineering or VCP and the firmware flash file.
What is the part number and software version of your Bluetooth module?

There isn't a newer flash file available unfortunately.

I retrofitted the 9WZ unit into my Octavia RS about 5 yrs ago.
Part No SW: 3C8 035 730 A
HW: 3C8 035 730 A

No issues with sound coming out of both front and rear speakers.

I had the RNS510 unit.
