[Android Head-Units] kaween:
I'd suspect it would, but I've no idea. But why go back to an old version if newer versions can be rooted ? *bit confused here*

Hi. It depends what is the most important part for you. And if you've not understood stuff I told you, tell me what, because in the end YOU alone knows what you want.

However, if *I* personally would look for a new unit TODAY, I'd go for RK3188 quad core based unit to get more "horsepower", like the newest Hufei&Co units that are coming to the market now. Reason : active developer community which allows to rectify a lot of things the AN21-U can do out-of-the box but the Huifei&Co can not, rooted and TRWP capable with at least a 7" 1024x600 lcd panel. The amount of tuning+modding for this unit done by the community is quite staggering. AND it supports RadioText in a better way, something I miss on the AN2-U (RDS support : perfect. Radiotext : Iffy)

What I would MISS when doing this (compared to the AN21-u machines) is the fast boot time of the AN21-U's compared to the Huifei&Co's, the capability of the AN21's to let you listen to the radio within 1 second of pushing the power button (the AN21-U will let you listen to the last tuned in radio station while booting, where other units will only come to life AFTER having booted completly, which means you have to wait a minimum of 30 seconds till you hear something from your speakers).

I *possibly* would miss the quite good Radio Tuner of the AN21-U which performs pretty well on both AM and FM bands. The Huifei&co's are reported to be nearly worthless in AM reception and their reputation about their FM reception is .... not really spotless, resulting in people trying to fix this with antenna amplifiers and what not.

Most people will say "hey but I don't listen to radio", but for me, a good radio reception is an absolute must. I've no idea if the complaints about bad reception is caused by bad installation by the users or if it is inherent to these units. Probably a mix of both. :)

I would NOT go for the Newsmy today. This unit has enormous potential but so far the promise far outdoes the actual out-of-box performance. My wife for example would call this unit "junk" because it can not do stuff TODAY which any stock cheap-ass stock unit takes for granted in terms of pure radio (No RDS, RadioText : no way, out of the box it can't even "sound duck" (meaning the radio sound goes down somewhat during GPS vocal instructions, coming back to preset volume afterwards). Even things like fader/balance/EQ functions are completly unknown to the Newsmy in the unmodded state. The thing feels a lot as if the mfg'er took a standards android box (because that is really what it is : the newsmy headunit is actually more a screen than anything else, the logic/gps/... all resides in a sepperate anrdoid box which is connected to the "head unit" part with a cable ...) and tried to use that for a car unit, but they didn't start by developing the hardware with car-use in mind .... I HOPE I'm wrong, but somehow I fear this story will not have a happy end.

Perfect unit for the nerdy (with all due respect) user who is willing to take a risk buying a unit which may becoming the best unit ever, or fail miserably trying to do so.

If I'd have to buy a unit for my wife's car, the solution would be an AN21-U, no contest. Everything "just works" out of the box. Period. You don't have the freedom of the Huifei&Co, nor the enormous potential of the Newsmy, but you get a unit with a very good sound quality, arguably the best of the 3 If I can believe people who tried all 3, a good Radio Tuner, fastest boot time and pretty unique "radio can be listened to even while the unit is booting" capability.

None of the units ticks all the boxes. It's up to you to decide what is important to you.

Recommendations : not really. Google->Aliexpress. :) If you find a unit that you think is good for you but you don't know if it is what you want/need, just post what you've found and we'll be able to tell you what kind of unit you've picked. Especially because you've stated it was for a new truck (congrats by the way, may it serve you long and well), but to make a recommendation we'd at least would have to know what kind of dashboard/car brand it is and how big the clearance is in your dashboard ?

I see "Ford Truck 08", but I don't know enough about American cars to make much of this. If it's a F150 kinda thing, the Huifei Dual core would be a http://android-caraudio.com/en/andr...rd-fusion-explorer-500-f-150-mustang-etc.html

If that model fits and you want a Quad, ask this seller. He's very responsive.

This person posted a YT series about mounting a AN2-U type of machine in his F150. It looks as if he used a bog-standard version of the AN21. He also posted extra tips about installing it ect, maybe it will be of some use to you : https://www.youtube.com/watch?v=3CjtFf_JK9k

TWRP nor CWM are possible at this time.

I've yet to see the first person on this forum who comes up with a solution to the "callibration issue after possibly bad flash". I'd suggest to contact your seller first.
