i have a golf 5 gti and want to instal a rcd 330, but will the radio turn on when i start my car, and off when i remove the key out of the ignition…
Yes. your description is correct. Only in this way can you prove that your unit is working under the control of a Volkswagen gateway, but for MK5 there must be a battery drain problem. You need to install a CANBUS simulator or replace the original one with a new gateway. The old gateway.
But if you have an 8-buttons multi-function steering wheel, you must install the CANBUS simulator to make your MFSW work for RCD330.
