Ford Fiesta 2012 infotainment upgradeWatch
I further needed the thin metal DIN cage, the anchor and fascia that screwed into the dashboard, that was quite costly, as it was an exact-fit for my model (a 2013 Mazda 5, part of the Ford family)
I needed a Mazda specific powered antenna to Sony coaxial adapter for another tenner, and a small but costly (£60ish?) Mazda CANBUS wiring harness and steering wheel adapter and decoder from a boutique UK car firm.
It’s a bit buggy, sometimes the Sony FM radio sticks on Volume level 14 ( a reasonable volume ), so I can cope with that. The steering wheel volume doesn’t decrease volume sometimes, but I can use the rotary knob. I’m not sure if the bugs are the CANBUS side or the Sony, but they are OK.
Overall, it works, took me ~ 2 weeks to collect all the bits, 2 hours to install, needling some serious tools to remove the old AM/FM radio. I could have easily added a reversing camera.
I am an electronics engineer, so that helped, but if you think you can do a serious car dashboard surgery (disconnect the 12V battery first!,!,!) Then you could probably manage, might be good if you had a friend to help.
You can probably get an auto-electrician to do the install for £50-100, if you supply exactly the right parts. I didn’t need extra amps or DAB+, I’m quite happy to have a USB for charging phones & passing the music/streaming-radio. (Apple-CarPlay would have added £1k) there are many cheap infotainment radios, of unknown brands, on eBay - I avoided those - but you’ll prob find a lot of “how to do it” resources online for those....read a lot, before unscrewing things...
Hopefully some of this will help, have fun. ( oh, and write down your current Radio PIN-Code, before you disconnect the +12V ) ( you might have to put it back, when/if you sell your Fiesta)
