Hi!
''It works perfect in an Altis 1.8.
But to answer your question, yes it does work in other variants but you will need to disconnect the 'direct current wire' in the grip which disengages the speedometer when the car is switched off and the key is out. This disables door open warnings when the car's off but works like it should and displays all warnings when the key is in and the car is started.
The speedometer stays on even when the car's off and locked if the 'direct current wire' is not disconnected.''
I've PM'd you my demand. :)
