Can someone school me on eBay Android head units for dummies?
So here's the deal - I'm not a electronics/tech guy. I have searched until my eyes popped out, and most of what I read is old, likely outdated, oft times contradictory, and usually dissolves (or elevates, depending on your tech comprehension) to high level tech talk. I can install and hook up old school stereos all day long. In fact, I just did one in my 2002 Porsche Boxster. I replaced all the speakers, two new amps, subwoofer, etc. To me that stuff is easy. My 2006 E55 AMG, that's a WHOLE 'nuther story. My car also has the Harmon-Kardon system in it. The system worked well, and sounded just fine to me. I like good sound but I am hardly a real audiophile. I read about fiber optics, interfaces, etc, and most of that sails right over my old head. So, what I would like to do is boil down the issue into just a couple of basic questions.
1- Is it possible to buy a eBay android head unit, install it with the appropriate add on gadgets, and have absolutely everything work just as it did before - all the speakers, steering wheel controls, etc on sort of a plug -n- play basis?
If yes exactly what do I need to buy? What is the latest hottest Android head available now for the W211?
2- If the answer to question one above is no, what will NOT work? Is there any easy way around that ?
3- Any additional layman-speak tips on this would be greatly appreciated.
