There is some truth in what was said, however, not a lot. There are people running radios fine in skodas without boosters, BUT, if a stubby ariel is wanted, then a booster is generally needed.
From what i have read I would get a good enough signal to use the radio, but seemingly not a perfect one - i.e. i am likely to get radio one fine, but kerrang and other local stations will be more fizzely.
I have decided to cancel the order with halfords anyway - i have done my homework and can get the same model online for £40 less; however, this doesn't include the Alpine Ipod interface (KCA420i) - which is quite pricy. TBH i don't think i'll do much better than the Halfords sale price, but i don't want to give them my custom anymore.
I's a stroppy ba$tard, i know.
