Fiesta mk7 stereo bluetooth

[Nebby]

Hi I am thinking of buying a mk7 fiesta approx 2009 to 2012, have noticed some have Bluetooth some don’t, the 2009 cars don’t but is it possible to change the stereo for a later version, obviously buying a slightly later car 2011 there’s more choice of cars with it, but there obviously more expensive.

Does anyone know if it’s possible to change being as it’s not a normal single/double din stereo that you can buy from Halfords.

Thanks in advance
