Hey guys, I usually just lurkj the forums but I figured it is time to ask the pros. First off, this is the unit I am installing today: Seems i cannot post the link but here is the title. from amazon Pumpkin Quad Core 7 inch 2 DIN Universal Android 4.4 Car Stereo Radio HD 1024*600 Muti-touch Screen GPS Navigation Without DVD Player Support WIFI/3G/Bluetooth/OBD2/DVR/Mirror Link
I am running a t-mobile service on my phone and I get free data for certain streaming apps. Its pretty cool. Anyway, I just learned that using the phone as a hotspot and then using one of these streaming apps on the device, in this case the new stereo, it does use my data plan... bummer. Anyway I am wondering if there is a wireless mirroring solution that would work and have control over the phone using the touch screen on the receiver? If there is not, how about a wired solution? I have looked into things like android auto. Does that actually work descent and on our receivers? Thanks everyone and a little nudge in the right direction would be awesome :good:
The pumpkin deck has a really basic bluetooth audio interface. I guess that would be the main thing I would like to change. I use Pandora alot and the interface on the deck is really basic. It gives me the option to skip track and play/pause. If I could at least get a similar interface to my old pioneer deck (id3 tags, thumb up/down) that would be cool. Or even a front end app, now that would rock.... Thanks again.
Hi
I am currently using Parrot Asteroid Smart, generally I am satisfied with the unit, sound quality is great, BT and other features works good, but the HW is old and max. Android version is 2.3.
I'm thinking about upgrading to newer android and the only possibility I see is one of chinese 2din HU like Ownice C500.
Does anyone have experience if they are any cons of such change? What is the sound quality of C500 compared to Smart?
Any info would be appreciated.

I am in the exact same situation. I was happy with the PAS at first, but it became outdated and frustrating very quickly - the lack of apps supported natively, the lack of ram and storage. Even after rooting and installing Google Play store there are so many apps that can't be run on 2.3. Positives though are that the Bluetooth call quality and voice command is in my opinion unmatched.
I have since bought an Eonon Android unit (rooted and installed Malaysk rom) for my wife's car and the interface is great, the sound is reasonable and the app support is great. The Bluetooth however is terrible, to the point of being unusable, the person on the other end can either not hear or suffers from major delay. This is a known problem with nearly ALL Chinese Android head units and there is a hardware mod but not being very confident in opening the unit and performing the mod properly and potentially voiding warranty is a risk I'm yet to take with it. I also have an issue where the physical volume control knob stops working and sound can only be adjusted on-screen, this is usually fixed with a reboot.
I still have not found a reliable unit to replace the PAS in my car after reading numerous threads that has Bluetooth quality on par with the PAS. Hopefully someone else here can recommend a decent unit?
Joying 2GB Intel is the way to go

Why?
look over some of the various threads on XDA, and feel free to check out the official Joying forum - http://forum.carjoying.com/
For the most part i think Joying gets the least amount of negative feedback, they tend to have pretty good customer service, and they seem to so somewhat monthly updates. I have had the older 1gb model and I currently have the newer 2GB of RAM model, and I'm a big fan:
here is a video review

https://www.youtube.com/watch?v=IUP4WGYHIaQ
but dont take my word for it, like I said, if you spend some time reading, you'll see a lot of the other head units have their fair share of bugs and complaints
If you want a fully functional BT interface, go with the Intel 2GB Joying head units. I think they are the only ones with a full stack BT interface available, the other Rockchip based units seem to have a somewhat hacked in BT interface which is limited compared to a full native interface, specially when it comes to how the Android OS can access and control it.
Install the apk from this thread and you have access to the standard Android BT settings screen, it is normally hidden in the Settings app but luckily it's not removed.

Thanks for the info
Few questions:
What is the BT handsfree quality with external mic installed?
Does the radio display station names? Does RDS and AF work correctly?
What is the general sound quality?
Does WiFi module connect with 4G router?
I use the head units wifi to connect to my phone as a wifi hotspot. Works great. BT handsfree with external mic is very good, at least according to those I talk to, I haven't been on the "receiving end" yet..
The sound quality is good, I'm still using the OEM speakers and they sound better with this head unit compared to the OEM head unit. Can't confirm on radio as I actually don't use it much... It does have RDS it seems, but don't know if it works or not. (radio where I live is garbage, nonsense content and music seems limited to whatever the top 20 list is...)

Thank you for the info. Which version do you use? I can see there are 3 different versions of 7" universal unit with the same hardware. The difference is that two of them have volume knob and the 3rd only touchscreen.

Both MTCD and Joying INtel have positive and negative feedbacks....
In terms of BT performance....both have BT Limited to MCU. Even you could pair from the BT standard menu, the functionality is limited. If i am not wront (correct me) both units CAN'T perform CALLS from BT by using google Now. Google Now recognizes correctly the name and it seems to start the call but never is initiated as it can not communicate with the real bluetooth Handsfree on the Headunit.
On the Intel units, the BT and wifi hardware is on the same board as the CPU, Android has full access to it. That is not the reason Google Now can't make calls. This is different on the MTCD units where the BT is a module which is sort of hacked in and Android doesn't have full access to.
I have bought Joying with Intel. BT handsfree works fine, although there are some other problems:
- no voice in Google Maps,
- when listening to the FM radio no voice output from nav apps except of Igo,
- I have connected Alpine active sub to the unit, sub works fine for first few minutes and stops, any idea why and what can be done about it? Sub worked great with Parrot, so it must be some issue with Joying.

I think if you change default nav app to your preferred one, you'll get voice output in FM radio.
For the sub - is the amp still ON after a few minutes when it stops? I have an active sub on mine and have no issues. I'd check on what your source for "on" signal on your amp is.
Google maps voice output doesn't work no matter what I do. As a default nav app neither.
Sub is powered and it works with very low volume settings, ad soon as I turn the volume up it stops working.

We got Google voice output working. Look into the forum.
Strange. Maybe I should reset the unit to factory settings. Reinstalling google maps did not help.
Any idea what is wrong with the sub?

(have seen a few oem ones) if so it would be hooked up with the sub RCA output ? Is the amp powering down ??
If so try hooking the remote line on the amp to an 12v acc line instead. (This is no different to the headunit remote 12v output just that if you switch the head unit off the amp is still powered on , this could eliminate a headunit problem ?)

As wrx216 said. I think it might be bad wiring. try a different SUB "ON" source. For example, I tap in the + wire of my rear speaker as the power on signal for the sub amp.
Google maps voice output still does not work. I did factory reset - it did not help.
I have updated the firmware and google maps voice works fine. But sub does not work at all now.
I have connected remote wire of the sub to constant +12V output (the same as amp. power supply) - it still does not work. I have also tried to change RCA input of the amp. - still nothing.
Modify Android 8.1 head unit for better menus & easier BlueT controller compatibility
I bought an iMars 7 from banggood, I believe it’s called a “Android Head Unit AC8227l” but from reading on here it could be a YT9217 or a YT9218 (?)
The menu systems I’ve seen running on these online, on pics or YouTube videos vary. But my menu system is quite clunky and limited.
I can connect a phone via Bluetooth for calls or on-device music controls, but I can not connect any Bluetooth controllers (I’d like a Bluetooth control for music and calls since using a touch screen and driving is a no-no). But I would also like to connect a Bluetooth games controller for my girlfriend to be able to play on it when we’re driving on long journeys.
Also, some better menu controls would be useful as the settings are limited at brightness, WiFi, and a few other minor things. Some display settings, better sound settings, and some others would be really useful.
I havnt wired the radio antenna in because of a lack of a female to female jack, and the reverse camera hasn’t been set up yet so their compatibility isn’t an issue right now!
Is there a way of modifying the software to allow for what I’m after? I’m decent with tech, but rooting an android device (even if that’s the correct terminology) is new to me!
Thank you for any help or advice

Sorry to say, but forget about all your wishes. BT is not available for other devices as phone and OBD.
Modifying the software to get this fixed... good luck...
Hi friends,
The head unit I have right now does not support stereo sound, and when I play any music from my iPhone the sound comes from both left and right speakers at the time!
But when I play from the usb using the music app, the stereo sound coming from the right and left speakers with HD sound that means the Bluetooth apps don’t work correctly in my head unit.
Also, when I checked the developer option, I found that the setting sets in another option not as stereo sound, I tried to solve this issue from the developer settings, but when I change the voice type to stereo, the setting returns to the original.

Anyone can help me here
Did you already take in account that the issue is not on the head unit, but in your iPhone?

Really thank you for your attention.
No, for one reason I have another car, and the Bluetooth working smoothly in the factory head unit. supporting stereo sound and HD sound. Meantime I opened the development options and I saw that in the Bluetooth Audio Codec setting the sound is not stereo. I tried to change it to stereo but the system didn't allow me. also, no build number and I opened the Dev options using a shortcut app in the store. it is really Stuped Headunit.

FYI
Well... OEM unit may work different, because they are completely different.
It´s a known fact, that those iPhones have problems with most of the Android head units.
You should contact the seller and ask him for a solution. May be there is one.
...btw: This is a quite old unit with Android 8. May be you can update your unit.
Look for STM32 thread in here.
