Yaris 2005 custom HU question

[stroebs]

Hi all, I've looked at everyone's HU mods and noticed all are the northern american stereo which come stock with the car so the side panels with the hazards and the passenger airback light are indented and don't have holes for the full HU which comes stock with my car.

My question: What sort of HU could I install in my Yaris? I've decided to do this car up as a hobby.
The car: 2005 Yaris T3 European (Right-hand drive) Manual with digital speedo and tach. (No onboard computer which means no electronic windows, fuel consumption meter, central locking etc)

Much appreciated
