You have to use the stock Bluetooth app for pairing (not settings》Bluetooth)

Check that you have set up previously the pin code for pairing your device.

For discovering and searching your device no other bt device must be connected to unit....otherwise you won't be let to search new devices.

After searching you will find your device with a "OBD " icon.

Pair it and check if torque shows it on he list of Bluetooth obd2 devices....if not you will have to use graser's app to allow obd2 to communicate with your apps.

Thanks mate really solid advice, it’s actually what I did earlier by trial and error. But will be helpful for any future non programmer skilled end users to search up [emoji1360][emoji1360][emoji1360].

As someone used to standard android and iPhone this way of connecting was unexpected but then again I did anticipate my android HU use wasn’t going to always be easy this really seemed impossible as ever experience I’ve ever had would be to go via system settings.

And last night I was actually told not to pair via Bluetooth app, so glad I ignored that as I did and it worked.

Disconnected my iPhone on a hunch during pairing too.

Thanks again.

I currently have a joying HU running a custom 4.4.4 ROM. The WIFI, Bluetooth, and USB controller took a dive so I'm back in the market for a new HU or repair this one for $100. I am vaguely familiar with how this market works that is why I am coming to you. The resellers are worthless when it comes to technical knowledge.

A lot has changed since I bought my original one 4 years ago. So I was wondering if the new PX5 systems are worth the $250 delta?

And have they fixed Bluetooth issue? Where there was a small crackle on the line that prevented the person you were talking to understanding you.

My most sincere gratitude.
[MTCD Android Head Units General] typos1:
You have a Joyous, not a Joying, Joying are a seller only.

The RK3368/PX5s are later MTCD/E units, yours is an MTCB one, the MTCD/E have a 32bit MCU (MTCB have 8bit) so they are more advanced, certainly getting an octacore (RK3188/PX3 quadcore MTCD/E units with Nougat and 2Gb RAM are also available) will give you a faster and more up to date device. However, you could also fit 2Gb RAM to yours and update it to 5.1.1. - Lollipop has been available for a couple of years.

What "Bluetooth issue" are you talking about ?
[MTCD Android Head Units General] tmiller101@gmail.com:
It was well documented on the original HUIFEI thread that there was a bad ground Or an impedance mismatch or just bad engineering when it comes to the internal mic. I tried several of the tips in the thread but could never make it usable.
[MTCD Android Head Units General] typos1:
Right, you mean the mic issue, it doesnt effect all units and the mic mod easily sorts the units it did effect.

Some MTCD/E units have a similar problem, like the MTCB/C units there are many manufacturers so youd need to read a few threads about them to see which. XRC RK3188/PX3 Nougat units do not work with Google Voice for some reason.

I'm sorry for this noob question.. Is it possible to root Dasaita PX5 units with kingoroot? I read somewhere that it hangs on HA/dasaita devices.
[MTCD Android Head Units General] typos1:
Yes, there are 4 or 5 threads about RK3368/PX5 devices, search them for more info.
[MTCD Android Head Units General] tmiller101:
Thanks, I don't really care about Google voice as much as I do care about being able to use the internal Bluetooth mic to make a call.

I also have a factory fender amp and currently only Eonon says they support it. Its frustrating because I know these people don't know their own merchandise. And I find mixer reviews here I guess I'll Just take the leap and see how it goes?

Is Android auto working out of the box for everyone ?

I installed Android Auto on my phone and connected via USB to the head unit but it doesn't recognize it.

Anything special needs to be done ?

Thanks
[MTCD Android Head Units General] typos1:
Any car head unit with RCA pre outs support aftermarket amps, MTCB/C/D/E head units are no exception, so you can buy from anyone, although you may need to consult forums about your car on how to set it up as different car manufacturers wire their amps in different ways.
[MTCD Android Head Units General] tmiller101:
Unfortunately its not an aftermarket amp. Its factory installed and controlled by the canbus. All the speakers run through it so no sound until the amp receives the on signal from the canbus. Its very frustrating. Eonon proudly says their canbus is compatible everyone else is unsure or don't.
[MTCD Android Head Units General] ab1702:
It will work but the problem will be that the sound isn't as good as what you've got now more than likely and you may get some interference through the speakers.

I've got an Audi A3 with Bose so it has a Bose amp from factory and the bass on the sound is nowhere near as good as when the factory Audi head unit is in and also there is some interference/alternator whine on the speakers.

I've done a lot of reading online about it and been talking to a very good car audio installer and the outcome is that these android units only give out one strength of power/signal to the Bose amp and it is too high for the amp.

When my Audi head unit is installed it can detect the Bose amp so it lowers the power/signal that it sends to it but the android units can't do this.

Not all a3's have Bose some have amplified speakers that aren't bose and it works fine on these vehicles the problem only occurs with factory fitted bose amps.

To combat this problem I have been told and read online that a hi/low convertor is needed as this adaptor reduces the power/signal sent to the amp and this would be installed on the rca speaker cables as that is where the power/signal is sent to the amp.

I'm awaiting mine to arrive that I have ordered from eBay which is a PAC model from America, I've had to get this one as it's one of the only ones I could find with 4 rca's on. I'm quietly confident aswell that it should do the job as the audio shop I know told me this and I also read it online so I'll update when I've installed it if it works
[MTCD Android Head Units General] tmiller101:
I appreciate the info. I currently have a JY quad core and like you said there is a noticeable difference in the sound quality. Especially a small whine or light static. And there are no RCAs in my Jetta, wish there was. But everything is wired into VW's wiring harness.

My concern is the first time I purchased a HU the CANBUS decoder didn't turn on the Amp, no sound what so ever. So I had to buy an aftermarket CANBUS decoder from PAC. It did not give me the full functionality I wanted. Eventually someone broke the code and Rambo at joying sent me a new decoder for $20.

Now I know better, I'm trying to avoid this nonsense by asking questions beforehand. But as we know the sellers knowledge is super limited. Since there is a limited number of manufacturers I hoping these other units also work just the resellers don't know it.

Plus, I'm hoping the decoder I have on my current unit will work with the newer PX5 units.

But again appreciate all the info you have.
[MTCD Android Head Units General] typos1:
It doesnt really matter is its after market, an amp is an amp. Have you researched how to add an aftermarket system to your car ? Pretty sure there will be a solution, sounds like its just a question of sending the signal to the CAN Bus system. What car is it ?

The Bose system in your Audi is set up entirely differently to [MENTION=3177293]tmiller101[/MENTION]'s system (its not done via CAN Bus) so its not correct to say "It will work but the problem will be that the sound isn't as good as what you've got now more than likely and you may get some interference through the speakers.". You have this problem because youre sending an already amplified signal to the amp to be amplified further. My car has factory Bose and it works fine with my unit. Bose often use the speaker outs for low level (RCA) signals, the solution you have chosen - a high low converter will not give particularly good sound either, although you wont get the distortion you get now. These stereos cannot send a low signal via the speaker wires, but they CAN send a low signal via the RCA outs, so all you need to do is buy an adapter that has speaker out DIN connector one end and RCA outs the other and connect the RCAs to your unit and the speaker DIN plug to the car sometimes this results in slightly lower volume levels depending on the voltage the Bose system requires, but this is easily sorted by buying a line driver or doing [MENTION=322215]7floor[/MENTION]'s sound mod. Its a far better solution than a crappy high/low converter and will give better sound as well. You didnt have to buy the PAC one from the US either, there are plenty available over here.

My Audi is wired up through a quadlock connector so it's not how you have just described and with this kgl unit I have it doesn't have any rca connections on the stereo either.

There is a connector which plugs into the back of the headunit for power etc and then one seperate connector which plugs into the headunit just for speakers which then on the other end has four rca's.. There is then another adaptor which plugs into the quadlock connector on the car and then links to these 2 adaptors plugged into the headunit but it does link the speakers by rca although that is just literally to connect the cables together as like I said it isn't an rca connection into the headunit.

Regarding the hi/low convertor i bought that one from America because there weren't many in England that had 4 rca outputs on like I am needing or the ones I did see were ridiculously expensive. As far as I can see and from what I've been told the one I've ordered is going to do exactly what I need it to do.
[MTCD Android Head Units General] typos1:
Some Audis have quadlock connectors, it doesnt matter, the principle is still the same - you simply need to connect the RCA outs from your head unit to the speaker in on the car, you can even make your own RCA to speaker in connector, its pretty easy, I ve done it many times on lots of cars including Audis. Ive also used the hi/low converters and theyre just not as good as proper RCA outputs. If you have the Audi loom/connector with the RCA leads on it, you just need to connect them directly to the RCA outs of the head unit, I ido it myself on an Audi with Bose and a KLD headunit just the week before last.

As I said, there are plenty of Audi Bose adapters on the UK, you didnt have to get one from the US, the ones from the UK are also plug and play, easier to fit than the PAC one, which I ve also used before.

ALL KGL units have RCA outs using a plug in loom that you plug into the back - look in the box and you will find it.

What youve ordered will do what you need to do, but it wont give the best sound quality and it wasnt actually necessary.
[MTCD Android Head Units General] tmiller101:
It a 2012 Jetta w the fender sound system. There are multiple ways to skin this cat I know. Just a HU that comes with a compatible CANBUS decoder makes my life easier. The Eonon systems claim to work but they don't have a HU with the knobs on the bottom, like Pumpkin.
[MTCD Android Head Units General] ikerg:
Ir eonon has a mtcd as well as pumpkin ....then order the pumpkin without can bus and order the can bus to eonon.

Just configure properly under factory settings

Yes I know all that if you would have read what I wrote that is how I have already got it set up, but you don't get as good of a sound quality as with the stock unit and there is also a bit of alternator whine.

I have had an android 4.4 unit before on a different Audi a3 that didn't have Bose and it worked perfectly fine but with this Audi that has bose and on the Audi forums where other people have bought these units in cars that have Bose you always lose sound quality and get a bit of alternator whine. The others on the other forum have bought a noise suppressor to get rid of the problem of the noise but that just kills the sound quality even more so I've been looking for a way to actually solve the problem and apparently this is the way to do it.
[MTCD Android Head Units General] tmiller101:
Yeah, I was wondering just how compatible those CANBUS decoders were. Because I was pondering that same thought.
[MTCD Android Head Units General] typos1:
I did read what you wrote, but it appears that you didnt read what I wrote, or forgot what you wrote - you said that you didnt have RCA outs, so you CANNOT have connected it the way I suggested - for it to work properly you need to connect it via the RCA outs, I know I ve done it to 20+ cars. I also pointed out that ALL KLD MTCB/C/D/E units have RCA outs via a loom that plugs into the headunit.

You ONLY loose sound quality if you connect it incorrectly, ie connecting speaker outs to RCA ins. Noise suppressors are for ground loop problems so anyone who has not correctly connected their stereo and then bought a noise suppressor is trying the wrong solution.

The only problem you may have doing it this way is a lack of volume, depending on a) the impedance of the Bose speakers and b) the voltage of the pre-outs on the headunit. But this can be overcome with a line driver

I have told you the way to sort the problem and yet, without trying it you are arguing against it !
[MTCD Android Head Units General] ab1702:
I have connected it the way you suggested because I'm not stupid and there is no other way to connect it and like I said before I've had one of these units with a different a3 without bose and it worked fine.

I did say that it hasn't got rca outs yes because the unit itself hasn't, it has a loom that plugs into the headunit that then had rcas on the other end so just because it has rcas on one end of the loom doesn't necessarily mean it's giving out a low signal it just means they've put some rca connections on the end of a cable.

Ive previously been told the android headunit is giving out a signal that is too high for the Audi bose amp as when the stock Audi unit is installed they detect the bose amp and go into a bose mode that lowers the signal to the amp so are you saying this is wrong because if I get a line driver then that is increasing the signal to the Bose amp even more?
[MTCD Android Head Units General] typos1:
If the unit has a loom that has RCA outs on it it HAS RCA outs !! So saying it doesnt have them is just not right.

The RCA outs DO give a low signal, this is fact.

As I have said I have worked on 20+ Audis with Bose (and other cars with Bose including mine which also gets the low signal from the speaker wires from the factory), so I know what I m talking about. How the amp gets the signal from the head unit is not really important - it needs a low level signal so with anything other than an OEM headunit it should be connected via RCAs. If the signal level is too high then the amp is NOT receiving a low signal and something has been connected wrong.

Some of these units give a low level RCA signal that is a bit low for some Bose amps, which is why I said once connected correctly, you may need a line driver.

Post some pics of how youve connected it and I ll tell you what is wrong.
[MTCD Android Head Units General] ab1702:
I haven't connected it wrong as there's no other way of connecting it, it's only a case of connecting f/l, f/r, r/l, r/r rca's. As I say this is a common thing on a3's with Bose that have these type of android hesdunits so it's not just me with this issue it's just that I'm trying to solve the actual problem rather than just buying a noise suppressor or ground loop isolator.

This is the item I've ordered and it is adjustable as it says you can increase or decrease its output so it should also do what you are suggesting it needs to do and increase the output to the amp so hopefully I should still be ok with this item then.https://rover.ebay.com/rover/0/0/0?mpre=https://www.ebay.co.uk/ulk/itm/361740249500

[MTCD Android Head Units General] eter711:
i never used bluetooth and have wifi connection bug, after 10minutes connection is stable, its software bug....
[MTCD Android Head Units General] Ga73:
Maybe yet another bug... All I know, like others if I turn bluetooth off on my phone wifi tethering is fast with no issues... I know bluetooth and tethering both use 2.4ghz so assume that's the issue as the wifi and Bluetooth chip I believe is combined in these units... I guess if you switch to 5ghz tethering (if it's possible) this particular issue would be fixed but it's not something I can do with my Galaxy s6+
[MTCD Android Head Units General] mojo4321:
I don't think these units have 5ghz wifi. I changed my hotspot to 5ghz and the head unit does not see it. I had a similar problem with a mini pc, but with that one I was able to switch to 5ghz.

A Mature Age NOOB Question - please be kind....

Hi All, I've read through all the threads and would appreciate some clarity before I plunge in and buy an Android Head Unit for my daughter's Mazda 3 2007. Key things she needs are Navigation (without internet access as many areas she travels have no Cell coverage) and music from her iPhone (Spotify or iTunes). Other things might develop, but this is the key apps that need to be bullet proof.

I'm keen to get the PX5 for the car, but XTRONS and Dasaita do not make a PX5 version specifically for the Mazda 3 and I would like to fit a unit that was moulded for this car with steering wheel controls that work, rather than fitting a fascia surround and general unit.

It seems Klyde do make such a unit - available from AliExpress (various stores) as a 6KGL-7638

aliexpress.com/item/HD-7-Android-6-0-1-Octa-Core-Cortex-A53-2GB-RAM-32GB-ROM-Car-DVD/32798002764.html?spm=2114.13010208.99999999.264.8hMa7N

Given there have been various issues/ updates that folk have had firmware updates for (XTRONS etc), am I making a mistake if I buy a unit such as the one I refer to - i.e won't get updates and things won't work?

Are Klyde ok regarding firmware updates for problems?
