Wow! That really sucks, no fan module in my unit either even though there appears to be a cutout for it. Its difficult to say what your problem may be. Dare I suggest that perhaps the rewiring of the power supply could have caused the motherboard to fry?
[Android General] getehem:
Since your unit gets a canbus, SWC should work without any set up ...this interface for setting up SWC is for the units & cars without canbus.

And since the power is still on the unit, check it out of the car, without canbus, using only ACC+ ( red) and GND ( black) connected to a 12V battery. It could be only the canbus that is not working properly .

I wanted to make my own theme about sion firmware, but one man give link on this.

Before I want ask some questions:

What is the latest firmware for device, and latest for MCU.

How work can bus for other, read upper that very bad.

And want add my experience.

Wants to add what sended me from china sellers.

I am on update2014-07-30-class.7z firmware and factory mcu. On my VW Jetta 2013 model year displayed climat, work buttons on left side steering wheel and some info on MFA+. On this weekend I have driving 7 hours and it is worked, but have some glitches with gps, music.

The entire Car info app doesnt work I think either the software or the canbus is faulty

Since the unit turns on and off when the car power is activated the can bus must be working to some extent.

To the guy whose system isnt working maybe the canbus connection has a problem?

My play store now permanently doesnt work, my music.apk usually freezes 4 times before working well..

I use google maps plus navigation for Navi and it works well.

Has anybody found a way of changing the startup logo?

Any ideas of how to prevent the system from stopping music while in reverse?
[Android General] jasiug:
I have also ordered this unit (SA-704) on friday, will share my impressions when it arrives. So in about 2 weeks or so. Little worried about what's already been posted here, but no turning back now I guess
[Android General] chirilas:
I've got a scion unit. The wiring is mostly wrong as in the cables don't correspond with the labels. After the latest update and playing around with the !(123)= its now working rather well.

Gps igo is awesome. Brightness issue was sorted and a few sound improvments to.

Carinfo app doesn't work. Canbus seems to work to some extent as the unit turns on and of with the key and cables wired to the canbus wires on the car.

In the settings menu you can select how the lights on the unit will react to turning the car lights on and of. these settings are quite important so the ilumination doesn't stay on all the time. you can also select how long the unit will be in sleep mode before it completely turns itself off. I chose 1h.

Does anyone have a pin out diagram? I need to rewire my aux in and camera rca.

Also, what does the pink cable do? Does it rely on negative ground to activate camera input?

How do I get reverse camera to work?

I ordered mine with dvb-t but that doesn't work. Doesn't pick up any channels haha.

BT microphone is dud to but have asked supplier for an external mic. Was hoping to get a wiring diagram and wire in my own microphone to the rear of the unit.

Screen is much brighter after recent update. The only bad thing is that even after setting up what each button should do, the radio app doesn't change station between the preset ones via the big toggle wheel anymore. Used to do it before the update.

Toggle wheel and changing tracks works with spotify and other apps tho which is good.

OH about to forget. My unit doesn't take CD's!! cd goes in almost all the way then gets stuck and comes back out again. might have to unscrew the top of the unit and see why the cd doesn't go all the way in.
[Android General] jxh99:
It amazes me that they don't provide an accurate wiring diagram. To reduce support queries, you'd think that would be the first thing you'd get right.

Did you order direct from sion, or from someone else? How have you found support so far?

What vehicle?
[Android General] bluetwok:
Pin out diagram should be on top of the unit you have to look at the diagram based on the port at the back of the unit rather than the socket itself, you will find then that the wires correspond mostly

You have to remove the two screws on the top of the unit before you can use the CD, found that out later

Yes I finally figured how to update my unit with the update, GPS Slot for my Audi A4 version was the one on the right, copy the update folder to a SD Card, Slot in the GPS Slot, press and hold down the Power button and Eject button together and it goes into Android recovery and recovers from the SD card, if no card in slot will recover from Root storage

Lots of new features after update, Slightly new look to radio app, the radio can be paused from the pull down menu on the top left, the music app has stopped crashing, I can go to the play store, the music app has new equalizer features of loud and something else in Chinese.

The extra car settings finally gives some control of the rear view camera, back-light etc. now the unit is actually quite wonderful to have.

Before the update i had no access to the 16GB iNand flash memory i was promised, i thought i had been ripped off. Now i can copy things freely!!

Having a few issues trying to access the media files on the iNand from the music player but will try work around it

Bluetooth mic doesn't seem to work with me too and had issues with the phone book before the update, yet to check how it is now but at first it was dialing wrong numbers.

Also ordered DVB-T module which didn't pick a single station don't know whether its the antenna or the module.

Try configuring the toggle wheel in the extra settings !(123) menu to skip tracks forwards and backwards and see if there is a difference

In summary after the update i feel i have a really powerful, great looking Android device at last!

car info app no longer says canbus error but in the menu there should be a menu to choose the car model which isnt there?

My illumination still seems to be misbehaving though will toggle some more though.

Many Thanks to Vladimir for the update file
[Android General] Vladimir2k9:
Great desription.

With my bad english i can not write so big overview.

car info with can bus choose, i found only in extra config menu !(123) and choose can bus there.

Now i wait can bus update for normal work of car systems. I am more satisfied with this firmware, too.

[Android General] bluetwok:
Thanks found the selection for Canbus in the hidden menu. Car Info app works now to some extent, shows the speed when driving but no information on the climate control system.

Bluetooth now works better with phone book unlike previously.

I guess the only problems left are despite the backlight options being turned to headlight relation as soon as you power off the car the panel key lights turn on.

Radio issue: Using the toggle knob highlights the presets but doesn't automatically select unlike previously. Need to configure a key for enter function in order to select preset.
[Android General] jxh99:
Sounds like the unit is starting to work well for you guys :)

In the meantime, I have a dead one, which I'd like to return to Sion for repair. But Linkey doesn't seem to be logged in to Alibaba chat these days, and that's the only way I was ever able to communicate with them (ie engage her when she is online). They've never responded to emails (to the plostar01 address).

Any suggestions how best to get a response out of sion?

Update files

Nice to hear that the update went well, but could you please provide some more details about what files you used for the update process ?
[Android General] bluetwok:
These are the links to the files used for the update process

Unzip the file update2014-07-30-class.7z which will contain a folder called "update"

Copy the folder to a formatted Sd card and put in the GPS card slot (in my case it was the slot on the right)

Now according to the instructions you are to reboot the machine and it will update but that didnt work for me. I had to go to recovery mode manually by holding down the eject button and the power button together.

If successful you will the android robot in the background will the writing on the screen shows the update in progress.

Let me know if yiu have any issues.
[Android General] AndreyMikhaylov:
When I tried to update firmware using this file update2014-07-30-class.7z, it didn't work when I used 16 Gb microSD. And with 4 Gb microSD all worked ok. I also had to use Eject+Power buttons to update.

Recovery (clear settings) prints only one screen of text and takes not much time, about one minute. When updating, it prints much more lines, scrolling about two screens of text and takes longer to complete.

Thanks to Vladimir2k9 for the files.

I ecountered some problems with software:

1. When I try to choose default navigation program in settings, whatever I choose, it says "navigation application error". I manually installed apk file from iGO forlder on GPS card. Also I installed Navitel and get the same error. When I start Navitel from applications list, it works ok. iGO supplied with DVD player says that language folder is missing or incomplete. iGO that I downloaded myself, is working ok, but can not bind to default navigation setting. Hardware NAVI button is also unusable.

2. Media player that is pre-installed in device can not play chosen folders, only whole sd card. I installed RocketPlayer, it works fine. Is there any possibility to link it to main menu? Also "panel keys" settings have no icon for media player, only for radio and dvd. How can I bind hardware button to Rocket Player or any other application?

I wrote email to support@szsion.com about my problems, and got only reply that they want to know firmware versions of my player. So they sometimes answer to mail :)
[Android General] bluetwok:
Yes, i encountered the same problems, at first Navi button could be configured to any app but with this update the navigation. Apk keeps crashing.

The stock media player sadly doesn't recognize media files from the iNand flash memory sadly but does fine from sd card or usb.

I guess those issues need to be addressed, which car is your unit in? Any issues with your panel lights?
[Android General] AndreyMikhaylov:
Let me tell you about my experience :)

My car is VW caravelle T5 GP (2010)

My unit is 7'' "dx.com/p/7-android-4-2-capacitive-screen-car-dvd-player-w-1024x600-ips-gps-rds-wifi-radio-aux-bt-for-vw-seat-320126"

I installed it by myself. I used 2 washers under upper screws to set front panel of the unit evenly with vw's panel. Also I had to saw off two tooths of antenna adapter's connectors, because they not fit to vw's connector.

Initial firmware was of version 2014-07-16, and I updated it to 2014-07-30.

When I used initial firmware for three days, there were some problems:

1. panel lights sometimes turned off randomly, but not stayed on when I turned off engine of the car and removed the key.

2. once GPS freezed, and iGO showed no coordinates, but showed 8 green bars of satellites, that were freezed.

3. once bluetooth phone call ended with infinite ring sound from car's audio speakers.

4. once I started video input application, and can not close it, only by reset of unit.

Then I cleared settings, and got unusable unit with all panel keys messed up, and this led me to this forum fortunately :)

Newer firmware version is more stable for me, except NAVI button problem. And it has more settings. I used it for two days only.

I did not try playing media files from iNand, but when I chose any disk in preinstalled media player, it played all what it wants, iGO voice files for example :( Files named .nomedia did not help.

I wanted to copy media files from CD and from android phone via USB - unsuccessfully in both cases. This sources are not mounted to /mnt. Is it possible to mount them?

Bluetooth in the unit has no settings that allow to share files with smartphone. USB also not working. So I can copy files from phone to unit only via microSD. This is sad.

USB microSD reader, that I inserted in one of usb sockets, was not recognized with 16 GB microSD card, and was recognized with 4 GB card.

Second USB socket does not recognize any flash drive, it is only for 3G modem I suppose, or it is broken.

Unit's screen is quite dark, and in my car it is tilted to windscreen so when the day is sunny, the screen is almost unreadable. But when the application background is white, it is more clear and readable, then with black background. Is it any possibility to change unit's theme colors?

GPS receiver is very fast and accurate (compared to my smartphone).

Sound quality is likely the same as RCD-310 that was in my car before. The volume knob is more smooth, especially in high volumes. But it seems I eed to adjust volume more often than with RCD-310. Maybe it is because RCD-310 volume depended on car's speed via CAN bus.
[Android General] Vladimir2k9:
I want to add on my own. I have the same problem. Maybe we should write on that mail and then can get corrected these.

With navigation so press the button and choose installing .apk and then a navigation app starts to run normally.

In Navitel you must choose that GPS always work or after stop it may not run.

Loved radio app, you can press the pause in the curtain, that it would add to the music player, as well as the pause button mute on SWC.

Only one USB port work for me too.

One chinese seller says that:

"and audi has the most problems.and the SWC of audi is debuging and testing till now."

What you think about to make theme on our 4pda forum
[Android General] AndreyMikhaylov:
I think topic on 4pda will be very useful, but I can not create and support it. I shall write there my own using experience if somebody will create the topic.

Also there are two topics about car audio units that are mostly the same as ours:

4pda.ru/forum/index.php?showtopic=539771

4pda.ru/forum/index.php?showtopic=595229

But there are no owners of these units, only questions
[Android General] chirilas:
I have an Audi A6 Allroad 2003.

Well look at the moment I'm not sure whats right, the cables in their sockets or the sticker on top of the unit. Some of the cables the way they came are correct but others arent!

As an example, the AUX in, I connected the left input channel to the white RCA labeled aux in L and the right channel to Video 1 RCA..... so yeah some cables are correct and others arent.

Can someone send a pic of their cables and especially the subwoofer out RCA????? I have the function in the eq settings but there is no sub out rca provided!!! grrrrrrr...

I ordered through aliexpress. I have to say after telling the seller I would wait with posting feedback until he had helped me sort issues, he has been most helpful. Well, he is trying. It's clear he has no clue haha but I apreciate the effort. He did send me the update file and new maps which I appreciated. Now I'm just waiting for the external microphone!!!

Again if someone can send a pick of their pinouts./ wiring that would be awesome.

Also, carinfo app doesn't do jack hehe. I have selected audi in the canbus option but yeah nothing.

There was someone here saying the led stay turned on the unit and drain the battery. Well mine does the same BUT. If i turn the lights of before I switch the car of it's fine. If I switch the car of and then the lights, well then the leds stay on. Again, that's a software bug as it didn't do it prior to the update.

---------- Post added at 07:25 PM ---------- Previous post was at 07:16 PM ----------

yeah i have the same radio issue with the toggle wheel. Was brilliant the way it changed before. I think it's more a radio app bug as the toggle wheel works fine with other apps.

I can't get my canbus to work at all! What model audi do you have? How did you connect the canbus wires? Pic?
[Android General] jxh99:
I've got a 2001 Allroad.

Attached is how I connected the speakers.

red: AUR RR to RR OUT

red: AUX FR to FR OUT

white: AUX RL to RL OUT

white: AUX FL to FL OUT

Do you have a Bose amp? I had to provide power to that separately.

This setup provided good sound via all Bose speakers (though the amp is always on when the unit is on, as opposed to when sound is required - see my earlier post).

DISCLAIMER: as per from my earlier post, my unit died after about one hour. Sion haven't responded to my requests for warranty replacement; will advise if that changes.
[Android General] bluetwok:
I have an Audi A4 2002 model, unit bought on aliexpress

Canbus only shows me car speed, you have to check while driving but apart from that nothing works.

Wired up as per pics in earlier post.

No subout rca that I could see, yeah sub out on the equalizer has no effect with me too

Its a pity about the radio and the toggle knob

I have had no luck with my lights. Have to power off the unit with headlights on, lock the car, unlock it then turn the headlamps off then the panel lights stay off!

Dont have a bose amp but the wiring as suggested above should work perfect.
[Android General] jxh99:
What country are you in?

To try to make sense of and prioritise the issues, I've made a Google spreadsheet summarising as best I can experiences reported here, 1 column per feature, 1 row per car/device owner.

Anyone with the link can edit; PM me for that. After a while, we can make it public so anyone can view.
[Android General] bluetwok:
Vladimir2k9 was able to get update files from a seller, maybe that same seller would be able to help address our concerns, I feel with better updates this could be a best selling aftermarket unit.
[Android General] jxh99:
Yeah, I think you may be right. If Sion can take advantage of the window of opportunity (while other suppliers transition to 1024x600), especially including getting its act together and providing decent support.

Since my unit died, I've spent more time than I care to admit reviewing my options.

The way of the future for the mass market is the www.android.com/auto approach, where a dumb head unit reflects your phone. Here and now, you can approximate that with a Pioneer "AppRadio" device (and similar from other manufacturers - no doubt that's where Google got their inspiration from). An advantage is you can probably get a good local warranty. Disadvantage is the 800x480 screen res, and no doubt missing app compatibility. A worry is: will Pioneer recognise the phone you have 5 years from now?

See http://www.ft86club.com/forums/showthread.php?t=28525 for more on those

Another option is to build your own using a Nexus 7. http://xdaforums.com/showthread.php?t=2103183 For Audis, see http://audisrs.com/ftopic49631-0-asc-0.php

and http://www.audizine.com/forum/showthread.php/526430-Nexus-7-Install

Interestingly, naiku at http://www.audizine.com/forum/showthread.php/526430-Nexus-7-Install/page2 was able to get his SWC working with the Nexus, using an rcjoycon part which converts steering wheel signals into USB signals. Pretty important, given you have no buttons on the Nexus!

The main drawbacks seem to be no radio; regarding calls:

But back to the generic Chinese Android head units; I've made another spreadsheet (!), this one focused on options available to Audi older A4/A6 owners: https://docs.google.com/spreadsheets/d/1MDHr4YxnYvVVVJrZxZxO5voLRASpz68rmFdEPK4Ykvg/edit?usp=sharing

I'll only buy a 1024x600 or greater unit (800x480 is out), for better app support. For why, see http://xdaforums.com/showpost.php?p=51723674&postcount=228 and following posts.

And given that HuiFei/kaigele don't seem to have a model for an older A6, and the other units are 800x480 (including Pioneer's SPH-DA100), for me at least, Sion and the Nexus 7 build-your-own approach are currently the only games in town. But I'm in the minority ... the other platforms will work for other cars, and some of them have much bigger threads (more experience/expertise) here on xda.

Does Sion have any differentiating factors other than 1024x600? Is their mst786 platform better than rk3066?

Bottom line for me, is that unless Sion honour their warranty and replace my broken unit, I'm currently most attracted to the Nexus 7 (ie DIY tablet) approach. YMMV :)
[Android General] bluetwok:
Well said, after sales service is typically poor from Chinese sellers especially if not purchased from Sion themselves.

If the bootloader was unlocked for modding by xda I am sure the software issues could be sorted out.

The major bug I believe is the BT module, if it could be for more than bluetooth audio and supported file transfer as well as torque it would be excellent!
[Android General] jxh99:
OK, here's a link to the spreadsheet. Edit away :)

[MENTION=5963347]bluetwok[/MENTION], in the second column "current top 2 issues", you could put the BT module, if that's what's bugging you most :)
[Android General] Vladimir2k9:
add about my.

Send link to thread to my seller, other seller and Joanna lin . Sellers says that send link to manufacturer. And no answer from Joanna lin
[Android General] chirilas:
Yeah I've got Bose to. Connecting it the way you have shown doesn't work. I've got a different connector for my bose amp, no rca's. Regardless, once it's all connected i get the typical popping noises once turning the volume to zero and back up again, or changing menus on the stereo. This was solved by an Autoleads cable - basically a high low converter. Works great now, sound is better than it's ever been even better than with the original rns-d widescreen unit i had in.

My issue with the wiring diagram on top of the stereo is that there are several plugs, A,B,C,D,E etc. Whatever it says on the sticker that they are supposed to do is completely different to what the cables say. Hence, I have no idea which one is actually supposed to be the SUB out rca, or which one is actually the reverse camera input.

My right audio line in - red rca, is connected to CVBS - that's a video cable. screwed up yes but it works.

Therefor I was wondering if anyone has a sticker that looks different to mine, and what do your cables say vs. the plugs they click in to? =)
[Android General] chirilas:
bluetwok, we seem to have bought our units from the same trader, Green point. The way your cables connect to the rear of the unit is very similar if not identical to mine. Can you please provide a pic of the sticker on top of your unit?

I'm not giving up yet on my quest of finding out which cables do what. I'm sure the sub output is on one of those pins!! :cool:

Did you manage to connect a reverse camera? How? :)
[Android General] bluetwok:
I think my connection might have been easier because I have non bose system

The first attachment is the sticker on top of my system

The second is a link which has another wiring diagram

This wiring diagram looks like a much better match for the system szsion supplied me! AUTO ANT and AMP_POW are on different pins!! That explains it..

That's the dodgy wiring diagram that was affixed to my unit :( Grrr...

I just purchased a headunit which I believe is the updated version of the Szsion (or maybe AN-21 U), because of the feature list and specification list. They claim it works with Bluetooth OBDII devices and their Bluetooth TPMS sensor system. Here is a link: http://www.aliexpress.com/item/-/1949646832.html

I also purchased the DVR camera for it... Will let you know more info when the unit arrives.
