I recently bought a Tesla style radio for my Fiesta and recently been told that its not compatible to the software built into the car.

Has anyone else bought this and managed to fit it?

there is no reason why it shouldn't work i was looking at the other model they sell then i decided to go with a plug and play amp and speaker upgrade, it would be the same as if you went for a double din, however you will loose some of the car settings through the original screen unless you have pre facelift ? but you would still loose the my key function and stuff like that.

another factor to look at is if you have the right connection for the lock and hazard's as i believe they changed the connection lead on later cars and you would still need to buy the correct plug and play leads from auto connects etc
