agree, the aerial just kept spinning. i was stumped also, but if you just grab it at the base and pull it hard, its fairly robust so will take it . give a good all tug.
 
Yeah TBH it was a bit of a daft question on my behalf because the majority of the time I listen to my iPod...however for the first time in years I have some sort of radio reception (it's quite bad as standard TBH, even with a booster) because I had a stubby aerial on my previous car for 4 years!

Something I could probably live without again, it's just nice sometimes not having to choose something to listen to.....I'll get one ordered :D
 
i always push em in then pull out and repeat as required until result is achieved





then relax lie back turn the snooker on and grab a smoke :)
