I have the Autoleads aerial adaptor for my car but reception is still bad.
The adaptor only has 1 input but the car has 2 aerials.
I went into VW today and one of the assistants (told me he used to work for autoleads) said that they did a double adaptor and Halfords would be able to supply it.
I have been to Halfords and nothing is listed in the catalogue except the single adaptor and when I just rang Autoleads they don't deal direct with the public.
