one thing to watch - ELECTRICS!!
second thing: if you are buying the car for toys - buy something else.
if you are in QLD then I rework the navi/TV systems. search my name on here for more info.
have your wallet out as this is NOT a cheap exercise.
as a marker I had a customer over the weekend that wanted two new remote keys. $700 thank you. they took a setp back for a sec and realised I was serious and asked why. RS73's post explains it in a nutshell. you bought a $90k car (in its day) and expact parts to be nix for it. not so.
you are aware that there is a japanese one listed on thise site and with a bit for mucking about with acrobat and google you can do it yourself
(btw AV section 'almost' done.)
you used the wrong thickness. 9mm works fine. if you trace the original panel you took out it fits fine. bear in mind there are left and right sides and they are different.
