yeah I would be a bit concerned about messing with the 4x4 controls....how about an in dash housing that will fold out your lcd?
I'm sure it would be possible...you are getting rid of the factory head unit right? If you do then you should have enough room to fight a lcd housing and a head unit in there. If it doesn't fit exactly you should have be able to make some minor modifications to get alittle extra room for it to fit. If you want to keep the radio there are other options for your carputer to still listen to the radio if you don't want to keep the head unit. I hear the reception isn't as great as having a head unit but it depends on what you want. Me myself I'm going without a head unit.
