MINI BMW . antenna base - removal- 2010 .

[oliverbmw]

Hi guys . this question may have been asked on PH before .?

I have just taken a flag( vinyl wrap) of the roof of a - 2010 BMW mini one.
However , i cannot get to the last small few piece around the rubber/plastic antenna /Ariel base unit on the roof .

Any easy ways of removing the base . or how is it fixed . do i have to take roof linning out ?
Thank s
