2008 135i OEM Hi-Fi System

Sorry if this has been beaten to death but I've tried to research here and elsewhere without answers to my question...

I would like to replace the BMW Hi-Fi head unit (S676A) in my 08" E88 with a double DIN 7" touch-screen solution with Android Auto and reversing camera functionality. I've got a couple of installation quotes, and both say I need a $500+ MOST amp integration harness based on the type of unit in my car. This almost doubles the price of this upgrade. Anyone cross this bridge?

Pioneer DMH-3000NEX $400
Plastic kit wo/OEM nav, w/auto climate controls $95
Antenna adaptor $15
HD backup camera $100
MOST amp integration harness *** $530 ***

Thanks in advance...

Check out Spiral audio. They have a bezel replacement and wire adapter kit along with the antenna adapter. But more importantly they have a little amp description so you know which kit you need. All you need to do is confirm whether you have the Lear or Harmon amp. The Harmon amp has optical inputs so the wiring harness is more expensive.

Also, try the Greenyi AHD 720 camera on Amazon. It's only like $50 and works great.

But, at the end of the day, if you do need the optical wiring harness then you're probably looking at close to $500 plus the cost of the deck.
