Need help picking a head unit!

Hello XDA'ers.
Just got burned buying a crappy no-name Windows headunit on Amazon and was wondering if you could help me pick a different one. I'm looking for an Android-based HU that can support Bluetooth, GPS and a backup camera. HD Radio support is a plus.
Thanks!

I am also researching for one and come across with eonon brand. You can check it out.

Do you have a link to purchasing it?

Actually, that one looks just like the piece of junk that I purchased. I'm hoping for a headunit that I can purchase and can flash with a custom from here.

For "Cheap Chinese" HUs, Newsmy type are the most popular here, followed by the older Huefei HUs.
I personally would (and did, but with a NEED for Android Auto) spend the extra $200-300 for a Pioneer 4100NEX with Android Auto and many other features, including US HD Radio. On EBay now for $500 shipped for refurb, or IMO better at $570 shipped brand new.
But if you need "full regular Android" to run any app, most "normal" HUs don't provide this, but maybe we'll get a ROM with full Android. Some Pioneer devices run Android under the covers and are getting a ROM now, in part to get Android Auto on devices like the older 4000NEX. I think that 4100NEX will get a ROM too, once it provides a good option for getting more than stock functionality.
The best "Cheap Chinese" HUs are stuck on Android 4.4 Kitkat at best and I doubt Newsmy/Huefei will ever get Lollipop.
These cheap HUs are also full of compromises and unless you understand and accept them, I think it's likely you'll regret getting one within 1-12 months, as you already regret what you have.

I read an Amazon.com review of one of the Chinese HUs where the guy said that the stock ROM on it was "OK," but once he flashed a custom ROM, everything worked great. He didn't provide a link to the ROM but he did say he downloaded it from XDA. So was wondering if there might be a decent head unit that I can purchase and flash and have it working well.

They are much better than you make them sound. Honestly they are very impressive for what you get for $100-$250 or so, you get a full android rooted system you can pretty much do anything with. And the quad core devices are very snappy and responsive, and the screens on the 1024x600 7" models are very clear and look great.
For the price, they are well worth it to me. The only real problem has been that the bluetooth design is not the best, and lots of people are just connecting a mic cable directly to the mic and ground pins on the bluetooth board to get around the poor internal mic issue. Other than that there is no real outstanding problem with them.

$100 ?
I thought the decent units, like Newsmy, started around $300 or so, and prices get higher when you need a non-generic, car-specific model.
To each their own, but I am still not a particular fan of Mediatek/Chinese chipsets. AFAIK, Mediatek still regularly violates GPL and keep more secrets than Qualcomm does, making it harder for kernel & ROM devs. Still true or no ?
Anyway, since I don't own one of the Chinese HUs, the opinions of people who own one may be more important than mine.
IMO anyone buying one should read the main threads for them for at least a few pages to get better informed.
For those who need "real Android" running on the HU, I'm recalling that the AppRadio Unchained Reloaded app seems a decent option for phone mirroring to Pioneer HUs.
I must sound like a paid Pioneer rep sometimes, LOL, but reality is that my best interests are in people running my Headunit app on tablets than buy an HU. But I only recommend that if it seems the best option for them.

I'm torn between the carjoying RK3188 and the NU3001 Carpad. Anyone have experience with both can provide a recommendation? I was reading some of the posts regarding the carjoying unit and am concerned that I need to modify the internal to get a decent microphone quality. Not sure if this needs to also happen to the newsmy unit? I have also heard that the joking crew provides great support, which is important and like the fact that they have taken the time to create lots of tutorial videos. On the nu3001 - I like that the android unit is in a separate box. I seriously can't decide...lots of pros on both units.
DJRepresent - did you make your decision yet?

Honestly. I've been both a newsmy & huifei owner... I'm not a happy camper with the newsmy and their support.
My radio was working great then started to develop random screen flickers & after a firmware update it died. Ordered a replacement Android box (as the head unit & Android box is separate on the newsmy, had to fight to order it as I didn't order my radio directly from newsmy but from a reseller... Only managed to get it as a fellow xda member was a reseller and he placed the replacement order for me) and my radio now only half works. My physical buttons on my radio (as it's a Volkswagen specific unit) no longer work.
Newsmy has left me high and dry with the issue with zero support on the issue. I've spent about 700-800canadian on this unit and I have now a half working unit...
I'm starting to think about selling off and getting a joying/huifei unit. As the one I use to own before the newsmy is now in my dad's car and it's working perfectly fine. I only got the newsmy as at the time it was the only 1024x600 unit with 2 gigs of ram...
I believe now the joying & even the winlink units have 2gig ram models with the 1024 screen.
The winlink seems to be less popular but also seems to have a representative from the company participating in the forum activity. Newsmy use to have that... seems they are no longer focused on the carpad2 more their unreleased carpad3. Not sure if joying/huifei has a representative participating but seems to have a lot more overall owners participating with the development.
One downfall I had with my huifei that the newsmy doesn't have is the canbus. The canbus didn't fully work with my car or my dad's car (my car being a 09 vw jetta my dad's being a '12 vw jetta)on the huifei I had random issues with it. I ended up replacing their canbus with another manufacture and the issues resolved.
Newsmy also seemed more focused on eye candy vs actually developing the radio more... It still has no rds support.
Also the newsmy has no sub preputs.
Hmm other then that... I think that's the end of my feedback rant. Maybe a joying user can chime in?

I like my unit from carjoying.com, the prices are pretty good, and the support is actually better than I expected. But NO NONE of the more popular units(Klyde, Roadmaster, Hot Audio, Joying, etc) which are all based on the same HueFui design, all use the same RK3066/RK3166 Chipsets, and they all have 1GB Ram. The memory and cpu are all using the same plug in daughter boards that plug in to the various main boards.
Frankly I don't see the 1GB being a limitation, or that 2GB would help all that much. The quad core is what seems to be a big difference and makes the units very snappy. I know my unit I normally have Torque loggings engine stats, iGO GPS doing navigation, MediaMonkey playing MP3's, and DailyRoads recording the front camera all constantly going at the same time with zero noticeable slowdown, and the unit remains very snappy and responsive. I am not sure what else you would want to have simultaneously happening that would be better than what you can already do with the current units.
The best models you can get are quad core, 1GB ram, 16GB onboard flash, and 1024 screens. I would just make sure you get one with these specs and you will pretty much have the best currently available.

Thanks for the reply! I read from a post you started a while ago regarding the carjoying unit you modified internally to address the microphone poor quality. How bad is it out the box (without modifying the internals) or is this mod a must do before installing? Is this mod to address just the integrated mic or does this also impact the external mic input? Wondering if i wire up a quality external mic if that would keep from having to modify the internals. Your usage list above looks like similar apps I would be running in addition to an occasional hands free phone call. Thanks!

Thanks for the reply! This is great info. I am truly sorry for your troubles. Hope you get your issue resolved. Support/customer service is something I highly value. Now that u mentioned it...I do remember seeing newsmy frequent presence in the large dedicated nu3001 thread early on, but they phased out as I skimmed though the posts. Thanks again for providing your experiences/feedback! +2 for carjoying

Honestly I just checked out newsmy's website and they have removed most of their headunits they once sold. So I would 100% rule out newsmy.
Joying in the lead but maybe check out winlink/ownice unit. As it's the quad core with 2 gigs of ram... I myself am 100% torn
I'm slightly shocked that there hasn't been anything new on the market. Faster cpu & more ram? Kinda sad that the joying unit doesn't have 2 gigs of ram. If it did I'd be jumping ship 12 hours ago as they have a nice looking vw unit that's all touch. Including the malfunctioning buttons that my unit has...

I'm a little shocked also, but from the feedback 1 gb should be good enough. I figure the units are somewhat inexpensive and don't mind replacing it a few years down the road if it becomes an issue. I finally pulled the trigger and purchased the carjoying unit. The crew has been in frequent communication with me since I purchased it making sure everything is right with my car configuration before shipping it. I'm pleased so far with the support and do not have the unit yet Hope my positive experiences continue after I receive it. Not looking forward to doing the mic mod though

Single Din flip up options? Considering Xtrons D766a

Looking to add a bluetooth radio for hands free calling to my old Chevy. Thought it would be cool if it did other stuff, Maps especially.
I find myself being drawn to the D766a by Xtrons. Planning to purchase a backup camera also. I have a few questions.
1: Is this a good option? Are there better units for comparable cost? ($339)
2: How Is the app compatibility? Will I be able to use Waze? Would this require a data dongle?
3: How do data dongles work? Monthly cost? One time cost?

Software and modification support is better on the rk3188 units. I would recommend you look on Amazon for either the Pumpkin or Naviskauto single DIN. I looked at the Xtrons and it had a few drawbacks. I think the only advantage was the higher res screen. One big deciding factor for me was ease of rooting the rk3188. Also the 3188 units support Bluetooth OBD, not sure if the Xtrons does.

Thank you so much for the helpful reply!
Like this one?
I had seen these, but was leaning towards the Xtron due to the better screen. If XDA stands behind the pumpkin, that really helps make the decision!
It looks like this does not come with an external mic?
Lastly, I still dont understand how the 3g dongles work... I assume I need a service contract? Id love an EL5... (Explain like I am 5)

I asked about the Xtrons here before I bought the Naviskauto, and got no response. The rk3188 based radios have much better support.
No external mic is true. I haven't had any issues with the internal one on this model. There is a hardware mod you can do for external that I presume would be similar on the single DIN, but you have to be willing to do small part soldering which I'm not.
3g would require its own line with your cell co and a SIM card. For me it was a better choice to get an LTE hotspot from my provider which I keep plugged in in the car. That way I just use the built-in WiFi on the radio which auto connects to the hotspot.

Thank you! I ordered one of the RK3188 flip up units on EBay for only $279. From my understanding the external mic just required the adapter from RCA to the universal headphone style plug? My truck has enough road noise, I felt an external mic was important. I'll let you know if it works.
My phone is rooted and can create a hotspot, I was considering the 3g dongle to avoid data overage charges. Thank you for the info!
Super excited to get this installed.

I have the Pumpkin RK3188 based flip-up unit and am generally satisfied. People that I call on the handsfree tell me that the quality isn't great due to the internal microphone. My vehicle is a noisy Sprinter cargo van. The supplied nav program works well and requires no internet connection. I use my cell as a hotspot to provide on-road internet

Looking at this unit as well for its single DIN and hide-a-way screen, how's it running now? Im looking at possibly Oenon's deck as they have 2yr warranty and costs less vs Pumpkin's. Is the faster core worth the lower resolution?
I too have a noisy truck (Volvo semi truck) so i guess i'll also have to do some kind of external microphone mod? I still have a mic from past deck, is there a way to do it with external line in?
lol this is pretty darn cool jumping from smartphones to now car decks!

I know this is an older thread, but I am playing catchup.
My 2009 Toyota Avalon has a weird non standard audio form factor, but I know people who have installed 7" flip up screens and they are good fit. (Specifically the Pioneer single din flip ups.)
I am drawn to the "universal" android style and have read some good threads on the Eonon GA1312 and it looks to be similar to the Pumpkin discussed here.
Is that still the commendation from those who are using them, or have they been super ended by something better?
Thanks!

Joying 5.1.1 vs Pumpkin 5.1 - 7" generic units

Hi knowledgeable XDA folk
I am going to purchase one of the below units - the price is close enough so as to be irrelevant, and the front panels are identical. I'm chosing this model due to the physical volume knob, rather than the other one which has + and - volume buttons.
My question is - are they the same under the covers? Is one better build quality than the other?
I'm in NZ so the country is comes from (assuming china or usa) is largely irrelevant.
It's initially for my GF's car - will be used for primarily for gps, radio, hands free calling. If it works out well I'll get one for my car too. In my car I'll be wanting to use the bluetooth music functionality, or upload a bunch of mp3s to it.
Did a bit of searching here, but almost everything I can find relates to the android 4.4 units.

Hey. I have a radio joying, but with android 4.4. It is very good, the screen is 1024x600. Radio does not freeze and restarts. Wifi works very well. In my stereo GPS satellites it is about 8, five of them have signal 50 SNR. The antenna of the GPS I got inside the car under the board, the shaft signal should be better. Microphone for voice is quiet and you have to speak very loudly. I got a free 8GB card. You can use the Bluetooth audio, the music is very good quality. FM radio is not receiving as good as my old radio, but I now listen to Internet radio or music via Spotify or TIDAL. Generally I highly recommend this radio.

I dont have the same unit, but I do have a Joying Android 5.1, MTCD, Jeep specific, and I am more than happy with it

Any reason you chose that pumpkin model? I'm currently considering a fully touch one because they actually mention the manufacturer of their bluetooth and Fm chips.
I've heard lots of bad things about the Joying radio, which is why I still haven't purchased one.

I've been researching both of these as well & the no name brands & all are pretty identical.
I would find a older 4.4 model with the same specs. 5.1's are still pretty buggy while 4.4 are stable & runnin well for the most part, this is what I've read from some of the elder members here.

Went for this model because of the volume knob. I guess it's not quite as sleek as the other model, however really don't want to be looking down to find a button. It's going into an older car without any steering wheel remote or other factory integration.

Probably too late to make a difference, but I have that exact Pumpkin model. It has a few issues and I ended up fixing them myself. I've rooted the unit and done quit a bit of customization, and will likely do more. The volume knob is nice, but since I installed speed-sensitive volume, I don't use it much anymore!

HU for mercedes W245

Hello,
Long time reader but here's first post
I plan to buy an android head unit for my car.
I need your help to choose a model that feet my needs.
My car is 2011 mercedes B class (W245). It's actually equiped with an Alpine INE S900R unit.
I'm sick of it because of it's poor fm reception, poor gps reception and interface and moreover the crapy quality of hands free bluetooth with no possibility to stream music.
I look for a head unit that fits in my car.
I read that i have not much to expect from fm reception and functions. In my alpine unit rds, af and ta doesn't work well.
I think i will go for 2Gb ram unit.
I have the choice between units with 7" screen, hard buttons and a look like an original command ntg. On the other hand i can have 9" units with soft buttons.
As i don't plan to watch videos and don't need a dvd or cd player in my car is a 9" screen a big improvement ?
Of course i want to have steering wheel control, gps, wifi, an entry for a reverse cam.
I'm in france so i think i don't really need dab+ as our radio stations don't seem to be in a hurry to use it.
I've read bad comments about mtcd_kgl, but it seems to be the most common platform to find units which fits in mercedes cars.
Thank you in advance for your advices.

I'm in the same boat as you, since I drive a Sprinter (W906), which uses the same unit as for the W245.
I had a MTCD KGL 7" unit for this car before. All I can say is stay away from KGL (like the 9" screen unit your referring to https://nl.aliexpress.com/item/HD-9...4.48010108.5.2.KL6ja5&&scm=1007.12783.72505.0). The quality of the finish was terrible and trying to contact KGL in order to solve things in a mature way was simply fruitless because they cut off the conversation. Apart from that, the unit your referring to is still a MTCD-unit. By now, the general consensus on XDA regarding this platform is to avoid it. Malasyk did great things in trying to improve the firmware, but in the end there where too many bugs and limitations on hardware level that couldn't be overcome.
So for now I think the only alternative seems to be the Ownice C500-version with the 7" screen and the hardware buttons. Despite several bugs, to me it seems to be quite good and think of ordering one in the coming days.
Interested to hear your opinions on any other options.

Thank you for your answer.
The C500 is not an option for me as it seems to have an awful FM section with no support of rds functions.
Having spent hours to read the forum and search on the net I think that there might be only one option: finding a mtcc_kld unit which fits in my dash.
Kld units seem to be sold by pumpkin. The problem is to be sure to have one kld.
Chinese sellers would tell you anything to sell their product.
It's a shame I'd rather have A big screen and 2Gb ram.

The Chinese sellers are awful indeed, they will try to scam you into anything. However, Aliexpress does seem to be more strict in enforcing the money-back policy in case you specifically asked about a feature up-front and were given a positive reply by the seller.
Just ask for a screenshot of the system specs and make it clear that you will not accept something else. Problem is however: what do you do if they send you something else anyway? Taxes and return shipping will be your loss anyway and the guy who has bad intentions knows that.
I don't know what specs the pumpkin model has you're talking about. I would never go for a 1gb model anymore, just too damn slow.

You are probably right. I'll wait till I find a suitable 2Gb model

If you really want to get a KLD unit... nothing easier than that.
Pumpkin is just a reseller for a lot of different manufacturers and you mostly don´t exactly know what you buy.
Go to the factory itself. Get in contact with them by chat and tell them your wishes,

Advice needed on first Android head unit

I have a 2007 GMC Yukon XL Denali with the premium BOSE system, factory NAV, XM, and rear flip down screen. What is most important to me is retaining BOSE, being able to use the factory backup cam, and being able to utilize the rear screen so my son can watch a DVD or video files I load on a USB/SD card. I believe with a couple of adapters, it can work if the unit supports it.
I have scoured the internet for weeks now trying to learn what I can about the cheap Chinese units. I understand there are just a few producers and 100's of resellers but all this stuff is still new and confusing . I am considering the Hizpo 7.1 unit(Android 7.1 Lollipop OS, CPU: Rockchip PX3 Cortex A9 Quad Core 1.6GHz, Nand Memory: 16GB, RAM: DDR3 2GB), amazon number B077SBX8CG. I believe these are MTCD_GS units. I want to be able to get the most out of this thing and am not afraid of using custom roms. What I don't want to do is get one that no one is modding. Is there much aftermarket support for this unit?
The hardest things to find out for me have been:
1. Can my son watch a video in the back while I have navigation running on the front screen? I think use of the RSE requires Metra GMRSAV adapter but not sure.
2. Can the unit feed my factory backup cam? I think it would require the Metra BackupCam adapter.
I would appreciate any thoughts you guys do have. I have no Android preference, just want something that runs smooth, and can be tweaked. Thanks

Anyone?

Anyone have any thoughts?

I have the same SUV. My HU is my own from a business venture where I went to China, met ODMs, and had a nice plan that simply didn't work out. The problems I get frustrated with are:
(a) Bluetooth voice quality. There is no comparison to Parrot although Xtrons new 8.0 units use (company acquired by Motorola but I forget the name). So make sure you ask WHO makes the BT. (Note: external microphones never are an improvement from my testing)
(b) Boot time. More apps = more waiting.
(c) Brightness at night is something I constantly have to manually adjust...auto is not auto.
(d) External amps are a waste - will not be worth it. The DAC sucks in these chipsets. Internal amp sound will be sufficient.
(e) Rockchip is better than Allwinner - and the old Intel Sofia units have the most customization from what I can gather.
So if I were to buy another unit I'd look at Xtrons, Pumpkin, Eonon, Joying, Ownice, and maybe LinksWell when they come out with a compatible or generic HU (they are the only one on this list with a US office.)
Also, you will need to customize a dash install kit - easy to find but I had to Dremel mine down to fit nicely. These units are slightly larger than Japanese standard size.

Thanks for the insight! I believe these are GS units so exactly the same as the Xtrons. Hard to get details on the web but will know everything when it arrives on Saturday. I bought with Amazon Prime so if anything is not to my liking, back it goes for a free return!
Lets hope its one that folks have modded before. Since I have yet to find a video of this unit in my vehicle addressing my specific camera and screen questions, I will try and do a solid review of the unit and post it here for folks.
Thanks

That should have a Ralink BC8 for bluetooth 3.0 (maybe 4.0) in which case your handsfree should be fine. They have 1.5-3.0V output on RCAs which is terrible but I'll keep my fingers crossed for you as this is standard output power for any Chinese Android HU.

Good to know! I don’t plan on running any external amps. My loud music days are over so I guess not too concerned about the RCA’s ?

Looks like it is a PX3, 7.1.2, MTCE_XRC_V2.75_1
Hooked it up after a lot of guess work because you know...no instructions. I have a low level hiss which is annoying, each turn of the volume knob gives a audible "thump" even when there is no audio playing, the unit doesn't fit in my vehicle unless the wifi antenna is NOT plugged in, and I can't seem to get BT audio to play.
I didn't have a ton of time to play today but I will tomorrow. Not sure if I have some interference with the wires in the back or if this is just par for the course and I need to return it and re-order a different unit until I get one that works the way I want it to.
