Yeah unfortunately none of the headunits available will be plug and play as the D2 is unique on many levels..
I have met up with MJ at her amazin workshop to do some other mods and once we have everything finalised I think we will create another more concise thread with a simple how to, depending on what head unit/setup you want to go with.
If this radio didn't cost so much I would have given up too, but I already stepped into this mess with one foot so I might as well take it through to completion and make other people's lives easier.
