Well, looks like you are right after all. Previously I waited like 20mins after key off to verify the 12v Battery line and it seemed fine and I didn't think much about it but now I am learning that the car (2007 BMW e90) goes to sleep after half hour and the workaround is to either run a wire directly from the battery (which is in the trunk for e90s) or find the right fuse in the fuse box that has always-on 12v. I guess I will try the fuse box first.

Thanks for your help

there is no fan, is that a problem?

A question here, I am having some issues with my GPRS dongle lately, sometimes it just works after booting the head unit. But mostly it won’t connect all, not to the service provider but the dongle itself, it is getting power but the head unit won’t see it, I have to reboot the head unit couple times to connect the dongle to the unit.

Is there a way to fix this? Like restarting the USB service for the GPRS dongle? This issue getting worst lately, year ago when I got the dongle it was working well but last month it is getting worse.

Google Now for voice commands

This forum has been very valuable to me as I bought a JY unit a couple weeks ago and have tried alternate ROMs, etc. Using Malaysk's ROM 4.4.4 on 3188 1024X600 with NEXT Launcher currently.

One thing I'd like to do is use voice commands for a variety of things. On my phone I can use the Google App with 'Ok Google' to enter commands which are trapped by AutoVoice and the commands can be interpreted by Tasker and tasks can be executed. When I try to set this sort of thing up on my headunit, I can't even get the Google App to stay stable. If fails almost every time with an error and it abends. That's before even going to next step with AutoVoice. Doesn't seem to matter which ROM I use, I get the same results. I've searched the thread but can't seem to find any information from others about using this sort of feature and how they did so.

Has anyone had any luck with using voice commands and the Google App? If so, can you tell me which version of the app you are using or anything you had to do on these units to get it to work? Or if you have another app you use for voice commands to interface with Tasker I'd be open to that as well.

When i start tomtom at home (in the livingroom with a battery/accu-charger)

then there are no problems, everything starts nicely! also tomtom!

But if I pull off the power at home, and put the radio in the car, all cables connected correctly

I start the car,.....the radio goes on,

I start tomtom,..... see the start screen of tomtom, tomtom goes out immediately. Message pop-up: GO IS STOPT!!, and tomtom is stopt.

I go to setup, apps, tomtom, delete cache,

then start tomtom again, Message pop-up: GO IS STOPT!!, en tomtom is stopt.

CarService Question

Are there intents broadcast by CarService which can be noticed by Tasker profiles when SWC keys are pressed? I've been trying to get CarService to work with BeyondPod without success, but figured I can do what I want using Tasker since BeyondPod has intents I can use to control playback if I can capture a SWC button press.

Update: RESOLVED - Found Proper settings in BeyondPod to make it work with the SWC without engaging Tasker to do more.

BEST POST EVER !

Thanks a lot to all the people involved in this thread. You helped me so much!

I was going crazy with the steering wheel command for three days now, when I realize it was just because things were not explained clearly.

Of course: you find two cables in your car for the wheel command, and the first thing you do is to plug them to key1 and key2!

I've now put the "remote cont+" cable on key1 and the "remote cont gnd" cable to the ground on the unit harness and now my wheel commands are working!

Thank you so much, this post should definitly go into the First post!

This is the correct setup for cars having the swc working with resistance. Like my KIA and Hyundai. A lot of cars have swc through the can-bus, so

this doesn't apply.

Internal/external SD/USB wont mount Android head unit

Hi guys, this is my first post so not sure if in the right place.

I bought a chinese android head unit with Android 4.4.4.Has 8gb internal flash, 2 sd slots, and 2 usb slots. It is

When the unit powers up most times it will have an error and not mount any of the memories (internal or sd or usb)

When you open file explorer it just shows that the internal sd card is unmounted. I have to restart the device 3 or 4 times before it works normal.

Tried contacting the seller in China and no help from them. I have installed all appropriate firmwares/mcu's applicable for my device (which is a JY manufacturer) several times and still the same issue.

It is getting very frustrating now and I can't seem to do anything to fix it.

Anyone know of anything please?

So now that I've been using this Joying head unit for a few more days I've noticed a few things.

With all music turned off I'm hearing some buzzing noise through my speakers and they stay there regardless of how high or low the volume is.

I do notice the buzz changes when I press things on the screen.

Has any experience this? I'm connecting up via the line out which goes to my factory amp and not the speaker outputs .

Is there a solution or a reason why this has happened?

When I open up Bluetooth is it possible to have it not switch off the music playing?

I was hoping to basically say have USB music playing and then say I need to make a phone call I open up Bluetooth (music still playing) and be able to make a call (music pauses) then once the call has finish it resumes the music.

Anyone know if this is possible?

What ? ! Any type should work.

He DOES update, just not that often.

This is basic stuff, its obvious that SWC Key 1 should be connected to SWC Key 1 and that SWC Key 2 should be connected to SWC Key 2 and that SWC ground should be connected to SWC ground, this is basic car stereo stuff and applies to virtually all head units and cars with resistive SWC.

Its sounds like you need a ground loop isolator.

You do not have a "Joying" unit, you have a Joyous unit, Joying are simply re-sellers.

Whats happened to your E46 ? !

Android CAN do that, but these units communicate with the car via an MCU and the MCU has to be compatible with your vehicle, so far the MCUs on these units are not. You could try connecting via OBD and haking the system so Android can speak to it directly, there may even be an app on the Playstore that can do it.

Maybe it is your English but what youve written is not correct - the MCU on AN21-U Android units (currently running 4.1.1 and likely NOT to ever be updated) CAN communicate with Ford Mondeos, but this is down to the MCU on those units and NOTHING to do with it being Android 4.1.1 and also NOTHING to do with these units being 4.2.2 (although most are now 4.4.4) - the Android version is irrelevant here, its down to the MCU and the devs of these units not having written support for that vehicle . . . . at least not yet. (EDIT: the Wikipedia entry on Android Auto says car data is "under development" so there may possibly be a solution at some point using Android directly . . . possibly, with some hacking I expect).

You just have to disassemble it and work it out I m afraid, but it shouldnt be too difficult.

The screen just looks really faded and has a grey/white wash over all the colours..

Just looks really bright even with the brightness turned all the way down.

As there are 3x ribbons im unsure to which one it is thou,

So, I did changed back OBDII BT dongle from OBD WiFi dongle. Everything works fine.

Also tried pairing the BT TPMS (http://www.ebay.com/itm/Car-TPMS-Tire-Pressure-Monitoring-System-with-Andriod-Phone-Bluetooth-Receiver-/271315933336?hash=item3f2bb09898&vxp=mtr ), but still does not work ( still does not have support..) meanwhile other concurent Brand does advertise their HU's with TPMS support, with that kind of TPMS module....
