if you backread, you'll see the different options the members did with their head units.. but in your case, if you have a 1 din monitor head unit, there's no problem, take out your stock head unit and replace it with your 1 din monitor. There's no where there that you'd even need to touch the multi-info display..
Unless you have a 2 din monitor headunit.. for those who have the 4x2 then you have to change your center console to the 4x4 center console to house your 2din HU. In this case, you don't have a multi-info display to worry about. If you have the 4x4, then you'd just have to yank out the multi-info display and store it in a box and never look at it again!

Now, you'll have a space to install your 2din HU. Back read to the post sometime oct-nov, you'll see pics.
