upon having problems with my car radio (hissing and crackling) was looking into guide's on how to lower the roof lining, and how to replace the aerial base......

NOWHERE had any specific to the Astra H ...... was just wondering if its worthwhile, and how, i post a "how to" on the site? as i've done the job today, and taken a few pictures in the process.

Cheers,
