I've just bought a Alpine 9847R stereo and also a PC5-52 adapter for the
antenna in my 1996 Polo.

My question is, how do I connect the blue power cable from the adapter to
the head unit?
On the head unit connection, there are 2 blue coloured wires coming out from
one slot, the solid blue is antenna power, the blue/white(or grey) is for
the remote turn-on connection.
Is it OK to connect the blue power cable from the antenna adapter to this
remote turn-on wire, since they are connected into the same slot on the head
unit connection and provides power to both these cables(solid blue and
blue/white).

Thanks
