Awesome thanks for this mate!

They have clearly put on the wrong sticker on top of my unit. This sticker looks more like what I have! Will print out and do a pin out this weekend =)
[Android General] jxh99:
The connectors on the back don't look like a Sion unit. Also, its only 800*480, not 1024x600 like the units in this thread. Have fun with it though :)
[Android General] bluetwok:
Looks like more of a downgrade to me

Lower screen resolution

Only plus is the OBD II accessibility which for audi owners like me reads very limited information.

I guess the DVR is a cool feature though. Looking at the connectors at the back you will have a lot of fun installing it! :D
[Android General] ZexGX:
I don't consider the resolution that poor, considering it will be replacing a Pioneer AVIC F700BT which has the same resolution but is much crappier. OBD II is a huge factor for me since my car does not have CANBUS.

[Android General] chirilas:
Ok so the sticker on my unit is completely wrong to the max.

The sticker you showed me is much closer. A, B, C etc seem to correspond much better. The main connector is wrong half way through. So far I have seen 3 different stickers and none correspond with mine 100%.

Can anyone else here show a picture of their sticker on top of the unit?

I am also convinced that plug D, which is n/a, contains the mic + and mic -. I want to confirm which pins they are as my internal mic doesn't work and therefor rendering my phone bt function useless.

My seller - Green Point has stopped replying haha.

[Android General] chirilas:
Well, from what I can gather Green point together with many others get these units from Sion then sell them on. They have no idea how to help with the issues so they rely on Sion to help out. No help from Sion - no more replies from Green Point.

Thanks for uploading the image. I'll take another look tomorrow.

Seems to me like nr6 - brown cable - is the reverse signal cable.

The brown cable goes to the canbus module. So obviously as you put the car in reverse the stereo gets the signal via canbus.

BUT... the canbus module mofo isn't working with my c5 A6 SO no reverse signal......... My thought is to cut the brown cable and give it a feed via a separate button - therefor I can activate and deactivate the reverse camera any time.

Million $ question: does the reverse signal cable require a positive or negative input? Do I earth it or feed it with 12v?

would anyone know?
[Android General] jxh99:
Have you replaced an RNS-D or an RNS-E?

If an RNS-D did you get a simple RNS-D to RNS-E adapter, or one which generates canbus signals, like http://www.ebay.com.au/itm/390794658493 or http://www.ebay.com.au/itm/110889420121
[Android General] chirilas:
I used to have an rns-jp3 but I think that'd be the same as a rns-d but wide screen for jap market.

Thanks for the tip re the converter! I'll deff have to look in to that. Maybe that's why most of the canbus related stuff in car info app doesn't work.

I would've thought that thats why they sent that separate can bus box.
[Android General] jxh99:
As I understand it, the older A6 C5 didn't have an entertainment canbus. The later cars with an RNS-E did.

Sion's head unit assumes the car had an RNS-E (and entertainment can bus), and the little can bus decoder they supply is supposed to convert the can bus signals to(and from?) something the head unit understands.

If the cables sion supplied you were the same as what they gave me (I'm betting they were), and those cables worked in your car, then (unless you already had some kind of wiring adapter?) you already have RNS-E style connector, and therefore - I'm inferring - an entertainment can bus and thus no need to simulate it with an adapter like the ones I linked to. Sorry if that sounds convoluted! :)
[Android General] bluetwok:
Another thing about the main connector is the direction in which the pins are labelled. Its a bit confusing when you are looking at the socket visa vis the connector. If you could print out an accurate diagram afterwards it could help others.

My wonder is do we all have the same wiring on our units or are there variants as per the 3 diagrams available and we end up being given wrong stickers on our units
[Android General] jxh99:
What's the third diagram? So far, I've seen two.

- the incorrect one which is on my unit (and linked in your post at #67)

- the one you photographed in that same post #67, which looks much better (and which is the same as the one just posted by Vladimir in #78)

Edit (8 Sept)

- chirilas has a third diagram, in #87
[Android General] bluetwok:
Sorry, my mistake!

But since none of these actually match your system there would be a third....
[Android General] chirilas:
Did you guys see my one?
[Android General] chirilas:
Yeah that makes sense. What your logic kind of points to tho is that the canbus box supplied with the unit isn't really compatible with the c5 a6 yet. All it picks up is: turning the lights on and off, aaaand.... hm .. turning the unit on and off..aaand... not much else.

I'm tempted to cut the brown wire and flick it to positive or negative to see if the reverse camera function activates. IF it does then I'll just hook it to a separate switch.

Who knows how long we may have to wait for a canbus software update from szsion =p
[Android General] jxh99:
The "can bus decoder" they supplied to me says for "Audi A3/A4/TT", software "Audi v2.01BI", and has a date on it 20131019

Have you got the same decoder? I'm not sure who makes it ... in Google images, you can see a similar looking decoder box for many other types of cars, but that's as far as I got.

---------- Post added at 08:34 PM ---------- Previous post was at 08:26 PM ----------

And we have, indeed, a new and distinct third diagram :)

I've updated the list in post #85

and usb did not work in android. Section B not work too :(

But better news, replaced ntfs-3g.ko from an-21 head unit and my flash drive with ntfs began work. Before cannot write files, only read.
[Android General] bluetwok:
How does this fit or work with our units?
[Android General] Vladimir2k9:
we have only one usb port. :(

But can use ntfs driver from other head unit.

Find intersting head unit

[Android General] jasiug:
Alright, I got my unit for some time now. I've updated the xls spreadsheet with my experiences and I'd like to add more, but..

Maybe there's something wrong with me but I cant get the headunit back out from the dashboard at all. On the front I got 2 holes that fit 2 out of 4 removal keys that came with the unit (and with which I was able to easily take out the rnse). The bottom right gets stuck inside as it should, the upper left does not. Nevertheless, when pulling the bottom right the whole thing won't even budge. Anyone got any idea, or can provide a photo of the removal mechanism of their units so I can figure this out somehow? (so I can post my wiring diagram, figure out how to connect this goddamn antenna, etc.)

Thanks in advance

J
[Android General] bluetwok:
My unit the removal keys all fit and the unit comes out well. Some units the keys need to be turned either inward or outwards in order to remove the unit. All 4 keys need to be in the unit though otherwise it may not budge.

The antenna connection may need an adaptor if your original unit uses a diversity antenna. I had to cut my wires and rejoin them to the socket supplied for the unit.
[Android General] jasiug:
Thanks bluetwok, appreciate your response and advice regarding the antenna.

It seems the unit won't give up so easily, the attached picture shows what I ended up with - stuck 2 out of three keys, brute force does not work either. Sorry for blurred pic - my optics are bit scratched. Also, contrary to common logic (or my logic at least) both right keys had to be inserted in opposite directions.

Anyways, it's not a hardware forum so I'll keep further hardware adventures to myself. Just posted it for the update and experience sharing sake.

Will be back with software summary.
[Android General] bluetwok:
You seem to have the exact same unit I do. Mine only has 3 slots for removal. I actually never pushed mine all the way untill my installation waw finished. Maybe you should try a different set of removal keys
[Android General] AndreyMikhaylov:
133

It is very interesting. In that unit bluetooth is more functional than in ours. It supports OBDII. I think we can try to install bluetooth drivers to our unit from it. Maybe all firmware is compatible with our unit, like in some chinese phones.

Also that unit has a little different body than mine. SD cards are placed a little different, and there are no holes in the upper right corner marked "IR" like in mine unit.
[Android General] chirilas:
reverse camera

Sooo for all you guys that have an A6 and the canbus doesn't recognise when the car is in reverse and thus doesn't show the image from the reverse camera - there is a solution!

Find the brown cable coming out of the rear of the unit.

Connect the brown cable to a separate switch and connect the switch to +12V. Flick the switch and voila! the unit turns over and receives the image from the reverse camera :cool:

Also using the separate switch means you can have it running all the time if you so want.

Hope this is helpful to some of you.

If anyone gets an update for the latest canbus please share it =)
[Android General] jxh99:
I like the idea of being able to have it running while the car is going forward: makes it easy to check the trailer is still there!

Well Sion eventually accepted a return authorization on my dead unit, so I should soon (at long last!) have Android in the dashboard of my A6 Allroad.

By the way, dx.com (deal extreme), Xiamen Dycaion, Jooy (branded as SICO), and Shenzhen Sunik Commerce all sell the Sion unit, so maybe people who are looking at buying or have bought from one of those places will start contributing to our little thread.
[Android General] chirilas:
Most times when I turn on the unit the volume is automatically on 14. way to loud for comfort and I always try to remember to mute or turn it down before I turn on the radio function.

Do yours do the same?

Also, i used to be able to go in to the video app and it would show me all the items on my memory card. Has stopped doing this for some reason. Regardless of the view mode... Have to go to file explorer and select from there. Anyone else have this issue?

Also, every now and then the gps looses signal between turning the car of and then back on. It can then take it aaaaaages to find satelites again. Weird, annoying, anyone else have this issue?

Also, how are we going with the wiring diagram? I still have to figure out which pins are for the external mic. I'm guessing at this stage it's plug D. My internal mic is not working rendering the bt handsfree useless.

=)
[Android General] jxh99:
Happy to be proven wrong, but when I asked Sion (Linkey) about external mic, she said - having apparently checked with an engineer - that the unit doesn't support that. (In spite of the web page specs claiming external mic is supported!)
[Android General] chirilas:
Oh ok, thanks. Annoying but if that's the way it is then that's the way it is.. .. I'm almost sure one of those labels mentioned and external mic. Oh well, not surprising I guess. Perhaps I'll try take the black frame of the unit and expose the mic and see if there's a cable issue or something. The lighting at the top by the cd slot stopped working a while back. Perhaps there's a dodgy contact there or something.

Thanks for the heads up!

Welcome to russian forum 4pda
[Android General] Vladimir2k9:
You described in google docs that have firmware version 20140905, where you get it?

Can you share with us.

Whats new, what mcu version do you have. Please describe work and features changed.
[Android General] Vladimir2k9:
Today upgraded to firmware from 08-22, the process was successful.

Before this make backups of /data and some other, because what seemed interesting, and the other should be standard.

After flashing, dragged too lazy to customize everything from scratch and restored from an image section /data and the most interesting thing he picked up and everything was configured as to firmware. Bad that when flashing overwritten partition Nand internal memory, but I'm make backup too. Copy the folder back Navitel and he earned too.

Archive folder with update and other firmwares in

https://mega.co.nz/#F!LR4yyD7C!9jguJYjEz1vorYV8yivzgA

called update2014-08-22-class-sion-oldtouch-mymod.7z

mymod - because has a small changes:

- replace driver for old touch

- replace driver for fs ntfs

- in /images/manufactorycfg/factory.prop changed the default sound level to 4 and the default language is English, to check it works.

Since I restored the settings from the old system, I have everything already set up and so far no glitches noticed. Noticed that was faster to work, I have earned export settings buttons. Appeared a new app apk shell or something.
[Android General] jasiug:
Hey,

sorry for a late response. It seems that I put the wrong number into google docs or I was wrongly informed by someone. Anyways, I guess that I had 8-05 at that time.

What is more, after updating to 8-22 (tried all versions, including your "mymod"), the touchscreen seems to be totally out of sync regarding the position of actual clickable content. It kind of looks like it has an information to work vertically instead of horizontally or something like that - noticed that when observed the correlation between discrepancies between places touched and places that actually responded on the touchscreen.

After using recovery everything is in chinese and the touchscreen behaves equally bad.

If anyone got any clue it would be much appreciated.

Does anyone know why TomTom is not compatible with this unit when all of the other nav apps work?

I can side load it on and it runs. Just does not see the gps location.

Is there a tech dude on here who can advise please?

Thanks Dobbo
[Android General] aitoroi:
Hello,

I found this post looking for people who has the same radio as me and it is really very helpful, thank you all.

I bought one radio to dx.com for a vw golf, and I am quite happy with it although the canbus was broken and I had to install a different canbus model to be able to work it, so my steering wheel buttons dont work. In the begining I couldnt use the navigator, but after reading this post I updated the firmware and everything works perfect.

I had a problem during the update, I installed the firmware not modified that Vladimir2k9 (thank you very much!!) uploaded and the screen worked wrongly: the control was 90º rotated, so if I went up, the screen went left, etc. After installing the modified firmware it works 100% properly.

The only problem I have now is the radio buttons are not properly mapped, so if I press home button, the cd player starts, with the back button another application, volume up and volume down are changed.... I tried to use !(123)= command, but nothing changes. Does anyone know how to change it???? With this my radio would be perfect.

Thank you very much
[Android General] bluetwok:
Try !(789)=

[Android General] Vladimir2k9:
read solution.doc from fw folder.

Everybody ask your seller for new mcu and firmware too. New come with 1.18, i expect that my parktronics being displayed.
[Android General] dobbor1:
Hi, does anyone know if this is the latest firmware for my system please?
[Android General] _Adik_:
SzSion and HUAWEI E1750

In case any of you would like to connect a USB modem directly to the szsion unit, I've found a solution that works with HUAWEI E1750 and software 22-8.

Please keep in mind that:

1) There are two usb ports but only one is dedicated for USB modem (so basically: if it does not work it means that you need to try the other one)

2) My SIM card has disabled PIN-code verification and it works, I will try with another card with PIN-code verification enabled and report back if it works

3) You need to specify APN manually (searching for networks does not work). To do so please go to Settings -> Mobile networks -> Access points names. Now please click on the option button on right and select "Reset to default". This step is not necessary but will remove all leftovers. Now from the same menu choose "New APN". You are obliged to put: name, APN, username, password MCC and MNC. All these can be found easily via google for all providers around the globe. Now, to save the new APN (as there is no OK button on the bottom) you need to press the menu button and click on "Save". The tricky part here is that you will notice that there is nothing on the list BUT actually it does not matter as it was saved anyway. In case the signal is strong enough you should be connected to the internet in less than 2 minutes.

What I noticed is that in my case, using USB modem somehow affected the GPS locking fix. Before from time to time somehow I was unable to gain a fix and now it is very fast and locks on more satellites than before. Maybe this can be related to A-GPS function of the software that is hidden somewhere, who knows... It works :)

Hope someone will find this useful.
[Android General] _Adik_:
Seems like you have the latest one, almost all of us here are stuck on 8-22 and MCU 1.13 (you have 9-17 and MCU 1.18).

Could you please tell us if (for instance) parktronic works? What does and what does not? What car is it?
[Android General] dobbor1:
Screen goes blank when the car is put in reverse. Steering wheel controls don't work properly. The internal and externally fitted mics are unusable. Nobody can hear you talking. The weather widget does not update location. Other than that just a couple of little niggles. It's the hands free part of the system I want working properly.

What is parktronics?
[Android General] Vladimir2k9:
What car do you have?

Parktronics is radio sensors at front and rear side car, i think you don't have it.

Can some one makes the latest firmware available?
[Android General] AndreyMikhaylov:
I tried some music players, and chose Mort player. It always resumes playback when I turn on ignition (if Sion unit sleeped, not rebooted), and doesn't crash.

It has widgets for displaying art, song and artist name, but the font is too small. I think it's Sion unit's launcher problem, it is not fully compatible with some widgets.

It also has screen layout for car, but it's not very useful.

Is it separate box with wires/connectors, or is it built in the Sion unit?

Can You post model / photos please?

Did You try to short contacts of audio input in reverse camera connectors? Maybe it will help.
[Android General] jxh99:
Hi Andrey, it is built into the Sion unit. The back of the unit is slightly different to my original unit (received around June), but unfortunately I didn't take a photo before installing it. The wiring diagram on the top of the unit matched one of the diagrams already noted in this thread.

I don't have a model number either, but it is the Sion unit HSXD supplied when I asked for one to suit 2001 Audi A6. They had offered me a separate TV box, to which I said "no thanks!" (given the probs people here has reported).

I can take a photo of the TV in action, if you like?

Tire pressure monitoring!

I bought TireHawk's Gen II TB-X04C system, and the good news is that you can see your tire pressures on the Sion unit :)

It has a little box which receives the sensor info from the tires and creates a wireless network Sion connects to, so the android app can display the sensor info.

The not so good news (minor glitches):

1. as you can see, it displays in landscape mode (the app also has a portrait mode, which seems to be the intended primary usual mode). From landscape mode, there is no access to the settings menu (or SmartLog, or About menus)

2. when the tirehawk app is in the foreground, it turns my music off! I'd like to be able to see the tire pressures and play music at the same time. (Apparently this would work if there was access to the settings menu)

3. calibration: the 4 sensors produce slightly different readings. sensor (1) and (4) read the same, sensor (2) underreports 1 psi, and sensor (3) underreports 0.5 psi.

It would be pleasing if the screen showed identical readings, when the pressure was identical.

4. Read out is in 0.5 psi increments eg 37.0, 37.5, 38.0; it would be helpful to get 0.1 psi increments, so I can calibrate them exactly, and after that's been done, to round up screen display to nearest whole number.

5. the external sensor is a little bulky:
[Android General] m0nt3r0z4:
i bought SA-7053 (BMW E53 X5 version), and have 2 problems:

1. Backlights always turn off everytime i turn on the car, the settings still ON but no backlight. I have to turn off and on again every time i turn on the car.

2. AutoDimmed function is not working, it only working (dimmed) if i set interior light on the highest bright.

no problem number 1, i think its only software 'bug', so i hope sion will release new update for the software. I dont know about the second problem, it might be the hardware :(

Anyone got the same problem here?

Is there any software update for SA-7053 version?

Btw, i already emailed sion. But no reply till now. (support@szsion.com)

anyone emailed them and replied back?
