On the door problem. It opens from outside no problem but not from inside. I don't think it is the child lock as opposite door opens from inside and out no problem
well, that is the purpose of the child lock: can open from outside, but not open from inside. to protect against children accidentally opening the door when you are driving.
from memory - i never used the feature when i had a 156 - there is a 'switch' you can slide between on/off for child lock. it should be on the door, accessible only after opening it, near where the actual locking catch is (below it?).
if it's not 'on', then indeed you may have a faulty mechanism. no easy fix, and will require removal of the door trim to inspect. even so, probably something broken, and not something you can fix at home, though you never know.
yeh its the one with aerial in the back window. im going to investigate the wiring behind the headunit. Off to Halfords for some tools.
Any ideas on how to wire it?
as mentioned, there is already an antenna booster. the wire to trigger it is the standard #5 wire in the ISO power plug. so, when you remove the headunit from the dash, trace the wires down to - what should hopefully still be there - the ISO (universal) plugs. they are like these black plugs: http://www.nexxia.co.uk/Car_Stereo_f...s/PC3-08-6.jpg
one is for speakerwires (locking tab midway along side of plug), the other for powerwiring (locking tab down bottom along side of plug).
in the powerwire plug, wire #5 is the 'antenna out' wire. the headunit should have an antenna output trigger wire (usually blue) connected here. refer to the general blaupunkt wire schematic attached.
chances are, it's already connected! other connections to check - including the actual antenna cable as mentioned - are on the back window. the aerial is shared with the demister from memory; so check the wires are firmly connected to the terminals of the demister on the window.
