Ok, so I bought my 335d used and it doesn't have bluetooth or iDrive (which is a good thing, seeing how outdated and user-unfriendly the system is). Originally, I wanted to retrofit the bluetooth, but that's about $1,000 for that installation.

So, I came across the Eonon GA8165 head unit and it seems good from the reviews. It runs on android OS and has bluetooth, Google maps, a touchscreen and access to all apps on android phones. It's also just $319, significantly cheaper than a BT retrofit.

So here's my question: is it worth it installing this head unit? I've heard some people say that you shouldn't remove the OEM head unit because it causes electronic problems. Does the Eonon unit do the same? Do the steering wheel controls work properly. How is the quality of the unit? I'm worried about it being a cheap Chinese unit.

Any Eonon head unit owners willing to chime in?
