Discover Media retrofit

[Delerion]

Recently i (VW CC gen2) upgraded my factory fitted RNS510 to a new MiB2 PQ G version.
Although everything works fine and as intended, i noticed the radio seems suffering from some very small hickups, random stutters in the menu animations, map drawing, especially zoom in/out is sometimes less fluent.

It's not very noticeable, but i see quite a difference in performance when the unit is just fresh started and how it performs after 30 minutes. it. So for me, it only happens when the unit is running for a while.

Initially i thought this was just a software flaw, something on the memory management that will become better after updates. And i just ignored it.

Last week, after a long drive, i removed the unit from my car as i wanted to connect a USB extension.
I discovered the unit was hot, very hot even. Could not hold the unit in my hands longer then 10 seconds, that hot.

So i decided to open the unit, to see what kind of cooling is in there.
Well... As for my G unit, it was even worse then i thought. On the bottom plate, there are 3 IC's (including the SoC) that are around 1 mm away from the metal housing, between there is some substance that i would rather call peanut butter, as it won't transfer thermal that much.

So i decided to improve the chip thermal transfer. Removing that yellow/orange 'peanut butter' junk, replacing with a 1mm graphite CPU thermal pad, and to make sure the contact will be most optimum, i also added a very thin layer of a high-end thermal grease ( Noctua NT-H2 ).
Also added this grease on the sound amp IC.
And as the unit is almost empty from inside, i installed a 5mm laptop CPU fan, that just fits perfectly on the air holes of the unit, so it will blow out all the internal heat.

Reassembled the whole thing, back into my car, and guess what.. Even after hours of drive, the unit is no more slowing down !

In my conclusion, before, my unit was getting so hot, the internal SoC needed to do thermal throttling, reducing its performance.

It's a relative easy modification, recommended to the ones who are experiencing degraded performance after a while as i did.

Yes the thermal 'paste' they use is more like a terrible type of foam.
Any time I have to open a unit up I scrape it all off and replace with CPU thermal paste such as Arctic Silver.
Haven't ever needed to add a fan.

[Delerion]

Yes, initially i thought doing the same, just replace the standard thermal 'foam', but then i discovered there is a 1mm gap, at least on my G unit.
Gap is just too big for any paste to efficient transfer any heat, so i decided to use (graphite) thermalpads to compensate the big gap.
Any thin 1mm piece of copper would be fine as well, as long both sides have any thermal paste to improve the termal conductivity.

I don't know if other models have the same 'gap'.

The fan should not be needed indeed, i just add it, because i had it laying around my desk here anyways, and there was room for it.
On some very hot days, it could help, as there isn't much passive cooling in that area anyways.

Hi to everyone! I recently retrofitted a Composition Media (5K7035200K) on my Golf 6 MY10 (replaced the RCD510). The unit has the hardware patch for the CP and in fact everything works except the voice commands.
However I have some small problems, I try to be brief.

1- The Composition Media has the ParkPilot active, but I do not have it installed in the car, so when I put the reverse gear the screen goes black and an error comes out after few time.
Unfortunately with the VAG I can't reach the 5F module (not even manually), I suppose the problem is the Gateway too old.
Are there other solutions, or am I forced to change Gateway?

2- The Composition Media clock does not synchronize with CDB and always remains at 0:00 (sometimes it appears as 6:28 and disappears after 1 second).
Is the problem always with the Gateway?
However the outside temperature is displayed correctly and on the CDB I see the song titles, radio channels, etc...

3- Sometimes, from the car speakers I hear a "pop": I notice it when I get into the car, shortly after opening the door. Has anyone had similar experiences?

Here is the scan with the VAG if it can be useful:

Your bad clone of VCDS is the problem, not the gateway in terms of being able to communicate with it.
Clock won't be correct because the instrument cluster software is too old. Only solution is install a newer cluster (this involves immobilizer matching).

For park assist you need to disable RVC low in byte 19 of 5F coding, and also disable in adaptations:
ENG122229-ENG117710-Car_Function_List_BAP_Gen2-parking_assist_0x0A -> not active
ENG122227-ENG117496-Car_Function_Adaptations_Gen2-menu_display_pdc -> not active
ENG122227-ENG117498-Car_Function_Adaptations_Gen2-menu_display_pdc_over_threshold_high -> not active
ENG122228-ENG117685-Car_Function_List_CAN_Gen2-PDC_audio_lowering -> not available

@kamold thanks for your reply!
Yes, I use an old version of VCDS, bought years ago to activate the led rear lights.So also with this Gateway it is possible to access the address 5F?

At this point I have two options:
1- Buy a new VCDS or ask someone to do it for me.
2- Leave the RVC option active on the MIB and purchase this kit: RVC OBD Dynamic

Right?

As for the clock, I think replacing the instrument cluster is not easy, and I don't know how to match it with the immobilizer.
Out of curiosity, which instruments cluster is needed to work with the mib?

The slight "pop" I hear from the woofers when I get into the car, from what can be caused?

[kamold]

Yes you can use the OBD Dynamic camera they work well.
A proper VCDS cable will be able to code address 5F without replacing the gateway with 7N0 version.
Instrument cluster software needs to be I think 04xx or above.
The pop normally should only be heard when you connect diagnostics to 5F. Maybe the speaker coding is not correct.

[Lele]

Thanks for your help! Last question, if I replace the Gateway with the new version 7N0907530BC, can I access the 5F module also with my old VCDS? Or support to 5F was introduced with the latest versions VCDS?

[kamold]

I think you'll need a newer VCDS to be able to access address 5F.
However I can't say with any authority as I have only used genuine

[DV52]

^^^ @Kamold: hmmmm.......... old VCDS instead of OBD2 version, clone VCDS instead of genuine VCDS and hacked hex5F module instead of FAZIT enabled retrofit!!

OP has certainly made lots of $ savings! Alas there must be a cost for all these benefits - I share your concerns!!
