Hello,

I have been looking on the internet everywhere, but I cant find anything similar to my problem.
Its touareg 7P 2011. RNS850 headunit. It takes about 15 seconds for RNS to start. After that sound comes from right side only and keeps braking (1second there is sound and 1 sec no sound and it repeats like this). It doesnt matter if its radio or songs from SD card or AUX connection in glovebox.

Did a full scan and there are a phew hooks. Channel 19 (Gateway) say that there is no communication with radio (Channel 56 ) and Tv tunner ( Channel 57). Everything else is fine.

So i took out the RNS, checked connectors there. Took out the radio in the boot (right side), repluged everything. Under drivers foot tried to get to j533 gateway module, which i guess is responsible for communication, but its in really tight spot and i can only see its 20pin connector, which is plugged in properly.

After all this, nothing changed and sound keeps braking. But during phonecalls sound comes normally, without braking and if im correct from both sides.

Any guesses what could cause this? Should I take out that J533 gateway module and replace it?

Hi there again. I managed to fix my rns850. After the update there are a few new channels in the list. But I do not have them. I think it was i channel 17 instruments. In the right corner next to coding you have instruments. Look there if you have double checked 56 radio channel. It was by me. After that clear all fault codes and there it was, the radio starts normal and all the speakers works just fine. Really hope to help.

Hello, thank you for replying to my post, but my sound hasnt fixed for me yet. I have tried replacing radio module in the trunk, the cd/sd card thing in the glovebox , but nothing changed. Now i started getting optical data bus faults, so it might be wiring problem for me. But as I mentioned before during phonecalls everything is normal. Tomorow I will try that thing with channel 17 you wrote about.

It would be great if you could clarify what you did to your car. Channel 17 is "instruments cluster" an I dont see instruments there. if you were talking about longcoding, in byte 10, bit 3 is checked, wich is radio/navigation system.

Hi, so after about 2 months i finally could get into channel 56(radio), which i could not do all that time. Went into longcoding, and changed byte 4, bit 1 to 0 or 0 to 1 (those sound profiles) and from than it works just like before. Dont know what was the cause of not letting me into channel 53. Could say it fixed itself

Hi! I resolved a problem with sound in my RNS-850. The solution from @Mladen is worked. I have had two checked blocks 56 Radio in the "Installations list" for Block 19 - Can Gateway. I am checked only one block, saved results and cleared fault codes. Then just switched off the ignition for a couple of hours. And everything works perfectly! Sound and radio. The solution is worked for me! Thank you, guys.
