Humn...doing a search on the web has turned up an adaptor on maplins website, code MZ79L which is described as:

Adaptor with the new 10mm ISO aerial socket to a standard car aerial plug.
Ideal for installing a standard radio into a car with an ISO aerial.

It looks like it'll fit the connector in the car, and the connector on the tuner module... looks like a trip down to cambridge car audio or maplins (urgh!) to suss this out....

Can anyone confirm that the clio has a ISO connector (i'm guessing it is because I guessed it was about 10mm and this adaptor says 10mm - and it looks the same) and that the tuner module is fitted with a din connector....

Thanks...
