[Android Head-Units] kaween:
Happy newyear !

The one you ordered is identical to the ones a large part of the users have got.

Providing you read the guidelines, don't flash mcu's that are totally wrong for your unit (flashing an mcu with a different hardware code for example) you won't get into trouble with that one.

Netconn has a pretty special AN version (motorized bezel) which I didn't even know existed before I read his topic. That's also why he's having a hard time finding the correct mcu I'm sure.

And to avoid problems, here's some simple guidelines that will keep you safe from harm in 99,9% of the cases :

1) only upgrade an mcu when you're experiencing issues. If your unit works correctly, do not mess with the mcu. There's no reason to do so.

2) don't mess with the "choose model" unless ... see point 1. (if everything works correctly, do not mess with it)

3) note down your units' system, mcu and DVD codes for reference. If something ever does go wrong, it will be much easier to rectify and finding the correct version for you unit in the multitude of different software versions for both system and mcu.

4) not sure ? ASK here. Then do. Not the other way round. Most of us do not bite. :)

5) sellers .... you'll only know if your seller was a good one when he's able to help you if you ever get into troubles. They all can sell. The number of sellers that actually KNOW what they're selling and KNOW what they have to do to give you support is small. Most of them are box movers, nothing more. A good seller will be able to send you the correct files, offer you a repair out-of-waranty by offering you the correct replacement part ect ect. Most of them can not.

6) SEARCH and READ the forum. Chances are your problem/question has been asked in the past already. Can't find it ? Ask again because as said, most of us do not bite. :)

And a HAPPY NEW YEAR TO ALL OF YOU GUYS !!!!!

I'm quite sure the poster meant to say he's abandonned the AN21 as handsfree unit, and uses a full Parrot kit instead. The whole echo/noise cancellation is not part of the mic, but resides in the Parrot box.

Using a Parrot specific Mic will not magically add those features to an AN21 (or to 99,99% of all these low-cost Android 2din's).

In the past, there HAVE been DSP-equipped boxes that used 2 mic setups and ended in a "normal mic output" that you could hook up to a normal mic-input, but the last time I've seen such a box is years ago, and they weren't exactly cheap either (150USD approx). But for the life of it, I can not remember the manufacturers name anymore.

PS : while it's not the box I tried back in the days (it was a golden colored electronic box, the size of a sardine can), Andrea Electronics is the company that makes these kinds of items these days. They're NOT cheap (300 USD) but I've seen them on sale on Ebay as second-hand units for as low as 50USD. There are a couple of really impressive demos to be found on the net with these things (the DA350 and 250), and if you're willing to risk 50USD and are not afraid of some experimenting, you can get handsfree quality in an unparalled quality for a fraction of the normal price.
