Ok, so a little update here. I have now done the Stereo upgrade, i fitted a Alpine 1 din in the car, and moved the original stereo to the boot, so i still have the old CIC system working. I installed the new alpine headunit with the powerpack amp, and the sound is much better than the original bmw headunit. All speakers still stock.
I installed a M-sport leather steering wheel, with multi functions, this i still havent managed to code in correctly. Tried adding VO 249 and 544, even tried 710 for the msport steering. Everything lights up but functions are fubar.
Did a suspension upgrade to, lowering the car with Harge springs and installed a weichers top strut bar.
Got the car tuned to stage 1 also, and cleaned the intake at the same time. (damn that one was dirty.. After 130k km)
Anyone here have done the multi function steering wheel retrofit?
As you can see i did not have any mfs, but the clock spring in the steering column had all connectors. So everything is plugged in, and coded correctly, using the guide on this forum.
