Loose radio on VCDS

Hi.

Can I connect an RCD500 that only has power to the CAN pins of my VCDS cable?

I mistakenly left it configured for a "sound system," and now I want to use it outside of a vehicle.

Okay, please provide the German text you would like me to translate into English. I will only provide the translation.

Normally, that should work because the device is directly connected to the interface via the CAN bus lines.

I would still prefer to connect it directly to the car again and then reprogram it.
