My radio antenna broke off inside the base and has to be replaced. I bought a new base, but it attaches to the roof under the interior head liner. Is it difficult to loosen the back part of the liner to replace the unit? Any tips?

 

Check out the threads about xm and sirrus radios in the audio forum, lots of info there.

Main prob will be the c-pillar covers, as they have a strap that holds them to the car if the side airbag was to blow.

Good luck
