You have a Bosch RCD 510 and yet you cant see the 56-Radio module in the VCDS scan. That is strange because that is what happens with aftermarket HUs. Those HUs are not accepted as Radio module. But a OE system has to be registered as a Radio module except some base line OE Radio units which are not CAN based units. RCD 510 definitely is detected as a radio module.. unless the unit has a chip/module which is not OE. Lets see... Does your system ask for security code after installation or upon re-installing after you disconnect the HU power for sometime? The reason I ask is, there are a lot of stolen HUs being traded online with the chip being replaced so as to get rid of the security code issue. This is what I heard and happens more so with the RNS 510/Columbus HUs. Don't know if RCD 510 have such problems.

Hi Ajay. The system does ask for a code and the code has been supplied by the aliexpress guys. Do we have to manually add radio?

On the ops and telephony, they should automatically come on if radio comes on. So my main issue is radio showing in vcds. Is there anything I need to do on vcds for radio to show before choosing the option in installed list.

Okay. So it could be that your car does not have a CAN Gateway. Or does it have one? If not, you might require something called a gateway emulator. I am not really familiar with installation or use of this but came across such a thing for use in cars without a can gateway for supporting modules that require a CAN gateway to communicate with the central module.

If you have a CAN Gateway, you have to check in the installation list within the Gateway module using VCDS that 56-Radio is selected. If not, select it. That is all you need to do and nothing more for selecting 56-Radio. The installation list would have all the components that version of CAN Gateway would support. You would see in the list, many items that might not be installed in the car. Radio is something any version of CAN Gateway should show up in the installation list, I guess, as it is one of the basic things. Advanced features might be missing on lower versions of Gateway module, but Radio should be there.

In VCDS, when you go to Select Control module screen, you would see 19-CAN Gateway. Click that and if your car has a gateway module, it will take you to your gateway module. Select the Installation List button within the gateway module menu. Rest as said above.

Actually there is a can plus and minus in the harness, which I connected. Without connecting these 2 wires, the steering controls and climatronic won't work.

So obviously some parts are working and some are not. This is what confuses me the most, unless climatronic and mfsw have nothing to do with canbus, which I highly doubt. But let me try what you said and see what happens.

Went through this thread. But i did not understand ANYTHING.

My simple question is:-

I have a 2011 Vento highline with the HU minus the sd card slot/bluetooth/aux/usb.

I want to install the RCD320(the olx add mentions this code) which was on a polo. It has the sd card slot/bluetooth/aux/usb.

Will the swap work. All i want is the aux/ usb to work. Dont care if bluetooth etc does not.

[deehunk]

Hi danlalan, the swap will work for Aux and SD card.

[danlalan]

So i did the swap and as usual the same problems propped up.
Which iam completely fine with.
Except the Hu buttons not lighting up. Although i have already memorized where the buttons are in the dark, i wish somehow these button lights could come on.

I am assuming you installed the RCD 320 unit with the Phone button? The RCD 320 uses CANbus inputs for turning on the backlighting.



Do you have the images of the stock black shaded ISO connector from your car? Like this:



Run a pair of cables from pins 1 and 5 from the black ISO connector to pin nos. 20 and 21 from connector B of the BCM, respectively. These slots should be empty in your connector now.





This will enable the backlighting when you turn on the lights.

Hello Everyone,

I too have the issues.
I had installed RCD 510 in my 2012 polo and kept the can wires unconnected since I could not find someone who can do the connections in BCM.

So I was using the HU without features like backlighting, switch off etc. Recently, I found in Vagtune website that canbus decoder is available for RCD 510 and RCD 320. I got the cables and installed today. Wow, everything is working perfectly. Actually I have a 2012 polo and 2015 vento. Swapped the RCD 510 to vento and RCD 320 to polo.

I suggest contacting Sugesh (Vagtune) with your specific issues and he can guide you.

Finally, we have a solution without complex connection needs.

I am myself planning for an upgrade to a 320 on my polo. It's a 2011 comfortline without system. I actually went today and got a pullout 320 from rapid from JMD Skoda. But when plugged the backlight of buttons didn't light up. Is your method tried and tested? He is quoting 6000 for it and I am in no mood to invest this amount without the backlight buttons. Please advise ASAP as I need to close the deal soon.

Hey did you try what was suggested by gannu? If yes did it work fine? The backlight of button started working? I am going in for a upgrade to a rapid pullout 320 tomorrow. Pls advise ASAP. Thanks.

Hey Guys, any update on the above? Does the wiring from the points to bcm solve the issue of backlight?

Hi I have an RCD320 that I bought off a gt tsi owner. It needs to be fitted into a 2011 polo highline will I need a canbus adapter for the same ? I dont mind if bluetooth or the button lights don't work as long as the sd & usb slots work and it does not drain the battery.Experts or anybody who has done this swap kindly help

[naikpranav]

Can one install an RCD 320 from a 2016 polo gt into a 2022 polo mpi?

From what I see online the port has changed post 2013? So should be fine?
