I hope you ordered 5Q0 035 726E.

That's the expected outcome. There's a small possibility that, for some reason, the USB was disabled when you first reset the multimedia to factory settings. Or that the USB got some internal error and stored error code, until you delete error code in 5F module it will be disabled. It's certainly not possible to solve this without diagnostics. Cheapest option would be some Real HEX-V2 VCDS clone (FlyOBD is best) on Ali for 50€, it pay itself very quickly.

ODIS, VCDS, OBDeleven... You can write original .bin but it would be very very weird if that causes problem with usb. I never heard of that kind of problem after activation fec. EDIT: Maybe you just didn't pluged in HSD cable connectotr properly in the unit when you put back unit in car after activation?

It is not common problem, try hard reset of multimedia with long press power button until logo show up. If still not working, try reset to factory settings whole unit. And last step would be to check with diagnostic tool for faults or posssible wrong coding/adaptations.

Reset to factory settings, only smartlink or whole unit.

What update do you need?

Hi, didn't tried that way. I belive it cannot be done so easy...

It will work.

This is topic for swing, aka MEN2 units, so this is offtopic and should be removed.

Did multiple devices with this method, never get this problem. There was people which had this problem, solved with desoldering eeprom chip, or desoldering atleast vcc leg. Before desoldering double check did you connected everything ok, try with and without 1.8v adapter, if everything fails, I would try to unsolder vcc leg.

Probably, it will work.

You need to reset to factory settings, just SmartLink settings or complete unit, depends which option you have. Path is something like Setup>Factory reset... I dont remember exactly, but it is self intuitive. Then you will get CarPlay.

Do you see CarPlay on multimedia screen when press App, without cable connected? What happens when you connect it, take some picture? Also is process of removing radio on rapid same as on octavia? For keys insert and pull?

Probably clamp not have good grip... Try multiple times, compare original .bin wit patched .bin, they should be the same in lenghth.

If it doesn't recognize it at all, even as "unkown device" in device manager then it is not driver releated. Try on another computer, if problem persist probably ch341a faulty.
