OK so while I'm sat here at 06:45 drinking coffee and eating my toast ill quickly answer a few bits.....
Well there is a guy over on M3post that retrofitted all OE equipment for the reversing camera to his M3 E92. Now it contains loads of info on how he did it, but mainly I used the coding info. Now his hardware should also work in our E89's as well, so this could be what the garage has quoted for.....

All I did was fit the Aliexpress module instead into the headunits loom for power and canbus. Although I don't have the parking lines and in-camera view rear sensor indications (full car pictorial view with front and rear sensors works perfectly though) I don't really use these anyway.
I hope that is of help
