how to get Power antenna to work with pioneer head unit in VT Berlina

[D-mac]

Thought I was pretty cluey with installing stereo's but this bastard has me a bit fcuked, The head unit im install is a Pioneer mvh 5280 in to a 97 VT berlina, The car has an electric antenna so that means there is 2 wires in the wiring loom in the car, Antenna UP and Antenna DOWN. The Pioneer head units only have one power supply supplied for antenna's, the blue remote wire. How should i wire it up for the antenna to go up and down? Ive searched around and still no real answer.
Things i have tried so far with no success
- Remote wire to antenna up = No good
- Remote wire to antenna down = No good
- accessories wire to antenna up = No good
- checked fusses = all good
Just to double check, the white wire is antenna up and blue is down?
Any help would be huge!!!! Cheers all

The actual remote wire for the antenna is yellow/red, hook the blue wire from the HU to that.
