Hi Guys, Im new here
Im in the UK and picked up my F900BT today. Looks like a great unit.
Ive done most of the wiring but got stuck. Im installing it in my 2008 VW Polo.
So far ive moved and grounded the mute from the white plug and also grounded the handbrake. I dont fancy taking my brand new car apart to tap into the switch!
But ive run into a few probs. One being the aerial. I need to use a booster with mine as the VW unit has it built in. Here is a pic of it

The silver and blue plugs are obvious but im stuck on the blue wire. I think its power but im not sure. The radio seems to have reception without it connected to anything but i remember when i installed an X1 on my dads van we had to do somthing with it. But i cant remember what?
The aerial is on the roof so its not motorised or anything. Do i connect this wire to anything?
The 2nd problem is power! I plugged the unit in and it came straight on. The keys were in my pocket so i guess its getting power all the time and needs to be switching on the ACC..How do i wire this?
Many thanks for any help.
