fordpartsuk.com is a good site, you can stick a description in to their parts request of what you want with your reg and they will give you a quote with the parts.
There are other places too, linked to genuine Ford dealers, although as Matt says, ebay or breakers might be cheaper.
Thanks for all the info guys, very interesting. I had thought of this but thought buyng everything in one go, already coloured up (in Piano Black!) was more appealing hence me asking if anyone knew of the company or website, now wished I'd ordered it at the time I saw it
Thanks for all the advice & ideas. I've reset the Bluetooth module (thinks the thanks goes to Nathan & his YouTube video, if it's his hehe) and hey presto it's now working, quite how Ford design/make a system like this is a bit beyond me but never mind I have my iPod back!
I've played the ipod through my home amp and works fine so doesn't need resetting. I've also tried connecting the ipod via an apple lead and tried plugging in an iPhone using the Ford lead as well, all to no avail.
All the other functions, CD, Radio, Phone work ok, it's just the AUX button/function that doesn't! Doesn't something on the unit need resetting or could just that one function have broken (as I can't select it through the menu options I don't think it's the physical button faulty!)
