Old Q&A-Thread - This Thread will be split into multiple KB-Thread soon

[Keylo Lo]

Hello to all!

I'm still looking for an android-device that supports kind of "Speed dependent volume compensation" as this feature already exits on (in-dash) other units, but Keylo told me that the KGL7683 so far doesn't support this feature.

1) Do you think it might be an option or possible to be implemented with a rooted device?

As far as Keylo told me this unit has one-way CANBUS, meaning that SWC works, but can not Display Information on the MFD.

2) Do you think a two-way CANBUS is realizable?

I'm still hesitating to buy this unit for my Audi A3 (8P)....
And hat I also dislike after reading this thread is that the Radio doesn't store the names.

good night.

Dear friend, happy to talk with you again.
About the "Speed dependent volume compensation", it is possible to work it out. But our boss was considered about demand and cost.
He thought it is not necessory for this function. How many people care about this? Do u have a qty for me? Then I can retell to my boss.

And the two-way Canbus, we still researching. Happy to hear if you all have any idea of it.
Thanks!

Good idea. I created a doodle to find out how many people is interested in the features mentioned above.

I can add more options so that we can make a wish list. Just let me know and I will add them.

About speed dependent volume and brightness, there is apps for that...
https://play.google.com/store/apps/details?id=it.playsafe.brightnessmanager&hl=en
https://play.google.com/store/apps/details?id=com.techelan.SmartSound&hl=en

Just random examples from a quick search...

Not sure they will control master volume and brightness if they have separate MCU settings, but If we do get a hint on the MCU communication protocol that could easily be achieved...

yes, there are apps but for instance brightness will not be changed when you are inside a parking/tunnel because it is just related to the day time. Anyway, if the unit does not have the sensor... it cannot be implemented..

Regarding speed volume, you need to have the GPS on for that to work, so it is not very useful.

Keylo said that the unit is 1 way CANBUS, so I guess, from car to unit. Since the car stock stereo already has the speed volume control, it should be easy (for HuiFei as they have the mcu protocol) to get that info from MCU and communicate it to Android. Sharing the MCU protocol would facilitate and speed up the task.

A much more ambitious approach I plan on taking once I get a working unit is the use of a IOIO for things like these and more (sleep, battery monitoring). The brightness for example will be controlled by the panel lights (as it should be able to already, is it not? isn't there an "Illumi" wire on this unit? does it not dim the screen at least some?) but with IOIO I should be able to monitor the panel lights voltage to change the brightness according to how our panel light dimmer is set.... It would be very possible to add a sensor to the IOIO BTW, but I like the Idea of it all going with the panel illumination.

As far as the GPS I don't see too much of a problem with having it on all the time in fact it will be good to have satellites already locked when you turn navigation on, other than maybe in tunnels but I'm sure that would be addressed by some of those apps in a way that when satellites aren't available keep it at the last set volume until they are available again....
Then again, I don't really care for that feature, I've had it before and ended up turning it off...

I see your point. The IOIO will give you all the freedom. But regarding brightness, isn't it easier to just have the same technology as smartphones? It is ready, cheap and works.

Ok, Video is up. Sorry for my ramblings, I do make a couple mis-speaks a few times, calling Wifi USB, etc...

Custom Recovery (CWM)
Open Source Firmware

Well, yeah, but the sensor is not there.... and neider is an inclinometer/gyroscope which is a bummer on a 4x4. I'd love to display the inclinometer gauges in torque when I switch to 4x4 (sensed by the IOIO)

The above would get me to buy one and replace my AN-21!!

So, it seems you have built in wifi... is there an external antenna? I see a harware mod coming already

 

[gangsta101]

I see a trend in the not-too-distant future where manufacturers monitor delelopers thread like these and come up with the perfect car stereo. Android has already made it possible, manufacturers just need to get with the program.

Thanks for the video ! I have included it on the first page.

I will not add these suggestions to the doodle as I assume that we all want that and Keylo is aware of it.

Could it be that the black of the unit does not much yours because it is thought for the last version of A4 ?

 

[nwskipro]

Thanks for posting the video!

1. Feedback/ground loop noise - Would this be an issue for those of us without Bose?
2. What's up with the antenna for radio? Is it just a simple connector that needs to be purchased?
3. Built-in WiFi - I didn't see any antenna for WiFi from the sellers pictures. Wondering what the actual issues are with the built-in WiFi?
4. Bluetooth - does it show song/artist info for playing songs stored on your phone?
5. TV tuner - are you planning on installing one?

Thanks

I do not think the ground loop will be an issue for anyone without the Bose. I talked to my friend at the stereo shop today and there an adapter that they use on all the german cars with bose, that fixes this problem. Im going to swing by tomorrow and pick it up

The antenna adapter they ship is for the non-amplified antenna in the back glass, which has always been crap. The antenna on the roof of the car (Shark Fin) is a powered antenna, and requires the other adapter. Almost any car stereo shop should stock this or its available for $10 on Amazon.

The picture used by the manufacture I think is the one with the built-in TV tuner as well. Where the two black wires are coming out of the radio in the top right (if facing the back of the radio), mine just has a single stiff wire coming out. When I pull the radio back out, Im going to investigate putting a SMA connector on this, so I can connect a 3rd party antenna and see if that helps.

I only tried with Google Music, and it did not. The controls for next song, play/pause all worked though. I do not plan on streaming much bluethooth since 99% of my music is in Google Music which I installed directly. Then copied my favorite songs over to a 32GB USB thumb drive. My ultimate goal would to be to get the USB to support a hard drive. Its my guess this is a power issue, but havent investigated.

I have no plans on installing a TV tuner. I do have an Aereo Account and with truely unlimited data on my Sprint plan and a rooted phone, I can stream all the live TV I want.

Awesome - thanks for the reply. Is the WiFi issue you're experiencing centered around the range or with connectivity going in and out? I'm planning on using a mobile hotspot (Freedompop ftw!) in the car so it would literally be no more than 2ft away from the head unit.

Thanks again, sir!

I initially had problems connecting to my home wi-fi, but after moving my home router about 10 feet nearer, I now get a good solid connection.

Yes its just a range issue. Wifi Tethered to my phone works like a champ.

 

[webdude12]

Ok, no luck on Wifi adb connect. Back to the drawing board.

And the two-way Canbus, we still researching. Happy to hear if you all have any idea of it.
Thanks!

The two way CanBus might be possible for things like the Radio, DVD Player, but would be hard to make universal across all applications. The biggest problem is the difference in all the vehicles.

I'm a little clueless on the Android OS stuff (WP8 guy here) - does Android 4.2.2 have offline mapping for Google Maps or is that restricted to a more recent build of Android?

And does it have mirror link? This looks to be the same unit and it's claiming mirror link capabilities: http://www.alibaba.com/product-deta...r-GPS-for_1652232645.html&af=cj_6147009&vd=30

Google maps does support offline maps and mirror link worked fine the little I tested it

tits that's awesome. I think I'm sold - just a little hesitant on whether or not I want the HD tv tuner (where to mount it for best reception and not see any wires)... Would be awesome to go out to the car at work and watch the world cup this summer!!

Ok, Ground Loop / Engine Noise are 100% fixed. You need this adapter:

http://goo.gl/dpdw4o

What you are going to do is disconnect the speakers wires out of the radio from the factory harness adapter. (We were able to push the pins out pretty easily). Then following the manual of the Scosche SLC4 you are going to connect those speaker wires to A1, A2, A3, etc on the adapter.

Then set the switch to "Line Out", I know you will want to set it to Factory Amp, but for Bose that is wrong.

Then connect the male RCAs from the factory harness side to RCAs on the Scosche piece.

DO NOT CONNECT THE GROUND WIRE on the Scosche Adapter to ground. Cut off the bare wire and wrap a piece of tape around it, Heat Shrink it, whatever you think works best.

The 100% eliminates all ground loops and alternator whine from the system.

Side Note: I actually extended the speaker wires from the back of the radio, so I could put the Scosche Adapter below my HVAC controls and out of the way of the radio. Also I adjusted the gain controls on the Adapter so that I could turn the radio full volume with no distortion.
