Szsion (i am not allowed to post links, google it, the first match is the one) produces quite nice android only (no ce) car navis that fit the design of different cars (audi, VW, mercedes, BMW, Kia, opel and many more).
I bought the Audi A3 version which looks quite like my now obsolete audi rns-e navigation plus.
I assume that the radios are technically all the same with different CAM bus boxes on the back and different designs. Sporting MStar SoCs (subsidary of Mediatek) they have a CPU powerful enough for car radio tasks and have a quite nice display.

I am also happy with the radio reception, which is as good as my original audi device. also i bought a realtek based dVB-T stick which enables me to use SDR along with digital radio, tv and FM in even better quality.
Navigation is VERY accurate, I even play ingress on it ;)

The only issues I have at the moment is CAN bus support, which is because I got a pre-sale sample with some firmware problems regarding can bus support and I can't turn display brightness to full at the momenr, but that could be fixed with a new software.

So , do you guys know something about those devices ? Anybody else owns one? I just saw that DX.COM is also selling them, so chances are that I am not the only one with this nice device..

Greetings

As a trading company selling car multimedia since 2007, we purchased some samples on may 15 ( all with either 8 Gb or 16 Gb storage memory). We are still expecting to see the first units....nothing has been shipped till now....
Also : SION shares it's office address with ZHINAVI, selling same units with another interface....please check what you'll find in XDA forums about this company...I don't want to comment publicly, only in private messages if you want.... For me they are sisters companies, even if SION denies it....I am rather anxious about this....

Don't worry about not getting the devices. They exist ;)
It seems that they are having some trouble with CAN conectivity which they claim is a software issue. I insisted on getting my device anyway and putting on software updates later on. Linkey is very nice if you ask her ...
They could also send me just 4gig model since 8 and 16 are not available yet.

They could, however communicate the problems a little more and not letting us wait 2 months without delivery, a mail saying that it will take some time would be nice...

The launcher they use is very nice, like on the pictures. The cpu is powerful enough for car tasks, gps is awesome. I have the best snr i ever had on any of my android devices.
Dvd playback works, radio is good. As I already said.

Anbody knows a rooting technique that MAY work with the mstar cpu?

I have been following these units as well. I have asked for a video of the interface so that I could see performance. Instead of doing a walk-thru like most companies, I got this, that I uploaded to YouTube.

I have also asked about unlocking the bootloader. It seems that the manufacture is interested in modifying his code to Android 5.x I told him if he opened up 100% of the source code to XDA, not only would he have a stable build of 5.x, but he would also have the best selling unit on XDA. I havent heard any more back.

I bought and received one of these for my 2006 Audi A4. It's working alright, sill trying to integrate steering wheel controls and the rear speakers aren't working, these two items aren't huge for me so I'm happy with the purchase so far. Also, I ordered and received the item within a week, crazy fast

Hi Riley!

Do any of your CANBUS features work or is it just the SWC that dors not work?
Also, how happy are you with the display brightness? Mine's way too dim for daylight use. At night, the display is very nice and sharp with beautiful living color, but with sunlight it really sucks so bad you almost can't see anything.

What's your software version?

I forgot to mention how AWESOME it would be to have source code access for this device.

KICK-ASS!


Anybody got an idea how I could try to enhance the display brightness?

I have similar unit for Audi A4 2002 model, rear speakers were not working but got around that by connecting the rear aux outputs left and right to the cables for aux inputs left and right!

I also have trouble with the Canbus support and the LED lights on the unit do not go off when the unit is powered down. Thats not good news for my battery. However the unit is very quick and GPS works smoothly....

Baidu Root works just fine.

The display is not great in the sunlight. I also think the colors are a bit washed out. The radio tries to turn on the back up camera when I go in reverse and the led lights turn off when I turn off the headlights, so I assume the canbus is working. I think the swc is a wire harness issue, I'm going to check it out when I feel brave enough.

Those with Audis, how does the plastic of the radio match the dash?? The HuiFei unit was a glossy and didn't really match the matte factory finish

Side Note... Those with the Audi that are having speaker issues. 99% of the time this is because the right harness combo is not hooked up. I worked in car stereo for years and tell you the Audi harnesses can be tricky. Sometimes you need to have speaker wires only, sometimes you need to use the RCA jack harness, and sometimes you need to use both.

DO NOT PM asking me to help with your car. This is nothing something that can be troubleshot over the internet. Has to be done in person. Your best best is too pull your radio out and the harness, You should have a separate harness that plugs into the back of the radio giving you RCA output. You will need to take these outputs and try plugging into the harness that goes into the car. A combo of these, should cause all speakers to work.

One more question for the Audi guys. The 4 buttons around the volume knob. Can you program these to do certain functions? i.e. One to be home, one to be radio, one to GPS, last one to be Google Music for example. :)

The default is home, gps, secondary menu and radio. I haven't figured out how to change them yet though

Ok, it might be a hack to change them then. Im waiting to order mine as the harness shown to come with the radio is not the harness I need for my Audi. Also been told that the new versions work fine with the SWC. Once I see a picture of what harnesses come with the new versions, I will make my final decision. :)

Anyone want to install CPU-Z to see what the actual hardware specs are??

You can change the button layout by going to the calculator and type in !(123)= or !(786)=(look what works for you) and then chose the 4th option.

Can anybody share me the gps program they got with there device, mine was navione and its in chinese i dont understand anything of it.
Thanks in advance

    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.

    OK, here's a link to the spreadsheet. Edit away :)
    @bluetwok, in the second column "current top 2 issues", you could put the BT module, if that's what's bugging you most :)
