Is there a remote boot popper for the 340? Or a central locking actuator I can fit with a homebrew pushbutton switch near drivers seat tghat would work with a "locked" boot? - fed up with unlocking boot all the time, and it is all the time.

yer just go to scrap yard and get a central looking mechanism (the bit that undoes the doors when you press the button)
go to you boot and find out which way to rig up the mechanism so it pulls pushes the lever in the lock and wire it in to a button
to were ever you want and hey presto job done you might need two one to unlock the boot then another to open the boot then you can
just lift up the boot hope that helps

Standard central locking motor wont really work due to the mechanical setup on the latch, however a generic boot pop will work.
