How do you remove the aerial unit on an Astra?

Answer 1

You have to open the tailgate and lift up the seal on the roof and pull the carpet on the roof back slightly then there is a gap and you will see a nut, it is a 19 mm nut. You have to then loosen the nut off and then the unit will be off you then have pull the wires through slightly till you see the wires wrapped up spongey type stuff you take that off the wires then there is a plug underneath that, you have to take the plug out. You then have to take the rubber hose out for the washers that just pulls off its quite stiff and that's it. It is really easy.
