replacing navi+dsp carver system with aftermarket kit while retaining steering controls

[z4all]

anyone have a guide on this?

I was thinking it should be simple enough.

the existing system (10 speaker + navi)-strip it out completely other than the 10 speakers

fit an amp, aftermarket headunit, connect the headunit and steering controls with this...

and finally turn the hole in the dash into a shelf.

anyone else done this? anyone see any hole in the plan?
