Nath you just made my head explode....
Oki, so first of all I need to determine if I have the original wiring loom in place (I assume I already have the standard Bluetooth module) and then I need to find a new module.
I found your video of the installation and it looks very simple, I believe I can even get away with just using a standard USB A receptacle to USB mini in place of buying the extra loom as I will be fitting this into the secret compartment.
However so far i've found many different part numbers, some relating to newer versions of the same module others relating to models in the same series for the Mondeo for example.
Is the 8M5T-19C112 specific to the year/model of Fiesta or is that just a standard component?
Hopefully I can find a scrappy nearby as I am having no luck on Ebay.
The software is going to be the tricky part, I'm going to attempt to convince the garage I originally bought the car from for the upgrade. The only two issues are that the only contact I have there is the shifty sales guy who seems like hes trying to crawl into my wallet and the main factor that there is a language barrier (British Expat)
For the Ford IDS do I need a specific firmware/software version, or is it simply enabled via a code? I need to be able to explain this to the actual workers and not the sales guy who will defiantly not understand what I am talking about.
