Easiest android headunit conversion for Navigation and DSP

[seanbreaux]

Hi,

I have a 2003 e53 4.4i with Navigation and DSP. My goal is to remove the factory head unit and replace with an android head unit with the least amount of cost and work possible. I want to keep my factory DSP. Is there any way to do this without running a cable from the front to the trunk and just straight swap the headunit? I was reading that the IBUS app may allow for this but I want to know all that I need to buy to convert and have the below functionality.

I want to have:

- Ability to control all car functionality that I currently can with the old headunit
- Wireless Carplay
- Backup Camera
- Bluetooth
- Use factory DSP


Here seems to be some mention of it.

Thanks in advance
