I noticed our VX antennas are identical to the one my VW GTI had. The VW Fuba antenna was amplified and the factory radio sent power to the antenna. When installing aftermarket radios a DIN-12 adpater was required to provide the antenna with a power lead.

Is that necessary with the VX antenna?

I checked behind the dash the other day and noticed a blue wire running along side the antenna cable. This blue wire ends at a small plug which is plugged to an orange wire running to the factory radio harness. Does this wire feed power to the antenna?

Thanks.
