Thanks for the thought but unfortunately I don't know anyone with a LCD unit I could swap as a test, I'm afraid.
A bit at a loss as to how to proceed, I'm considering swapping it for a cheap double din android unit so I've been watching progress here carefully -

but it seems installation could be a nightmare and the 1gb RAM unit might also be a problem.
