Navi replacement with Raspberry Pi / Android car “Crankshaft”

Since my C70 yes – thanks to the “tolle” Volvo DVD drives – has for a long time no working navigation, I was thinking about replacing the fixed installation on top of the dashboard with a Raspberry Pi solution with Android car … the punched part I think can be completely levered out, there then simply a 3d-printed bracket pure, reasonably wired and finished … Has anyone here ever dealt with this?
