You have a BC6, I doubt any other module would perform any better. If recording via an app on Android, the BT module is not performing the recording, the SOM does this.

Having listened to the audio, suggest the following might be happening:

Noise from car/ignition is entering headunit.

- check headunit supply from car for supply drop and good Earth.

- Mic circuit - do you have an external mic connected? If so, try disconnecting internal.

- Bad alternator (diode or regulator issue)

Unit power supply defective - check main reservoir electrolytic capacitor, dry/poor solder joints. Check power supplies to MCU, SOM etc for noise (oscilloscope) and stability.

- Poor/bad earth either in vehicle or headunit.

Car sounds nice, what is it?
[MTCD Android Head Units General] Ilkinansr92:
Haha its an older 2005 lexus ES330.

Also found the datasheet. http://www.datasheet4u.com/datasheet-pdf/CSR/BC6130/pdf.php?id=944249

-No external mic, I did buy a high quality internal mic and replaced it. https://www.mouser.com/ProductDetai...csMZaWNSqu/z0YbdNREjMUm3Xf2SS5aFgo2wF7HdUUg==

- first my ground was connected to harness where Lexus HU was connected. So I though it might be it. Got a bigger gauge wire and connected directly to chassis. Same issue.

-if unit power supply was defective wouldn't I have issues with that noise even while listening to music. Not just while I'm recording?

I though it might be alternator noise or even fuel pump. As it happens only with Acceleration. It might be fuel pump as I am hearing some high pitch noise near fuel tank while car it running.

But once again no noise through the speakers while listening to music or the unit just been on. Only while I record and accelerate.

StableGenius,

Can you give us some pics from the DSP chip and are you still pleased with the radio? (can you make a video of the radio?)
[MTCD Android Head Units General] Jkteam:
I hope he is I am waiting for mine
[MTCD Android Head Units General] Superman0621:
radio reception is fine where i live.. I have 2..and i am glad you asked i did not even notice that was a second antenna wire lol.. So i will post another reply to you after i get the adapter to make them both 1 from amazon...

Question for the rest of the group - does Xtrons post firmware updates how Joying used to do or do you have to ask them individually for a patch?
[MTCD Android Head Units General] skezza:
This unit runs the same firmware as mine.
[MTCD Android Head Units General] Ilkinansr92:
Had to ask.
[MTCD Android Head Units General] jakejm79:
That will depend on the car, if the car uses resistor array for the controls then it will work (i.e. there is a different resistance between the two wires depending on the button you press) but if the car uses canbus (or another bus type) for the controls you will need an adapter box.
[MTCD Android Head Units General] Superman0621:
I had to use the adapter because my car did not have steering wheel control because of the age.. but yes you are right with everything you said..
[MTCD Android Head Units General] bogdi1988:
Ok. Just finished the install of my unit in my car. I am coming from the Intel Joying and I had my amp chip replaced with the Pioneer one.

1. The sleep function works SOOOO well compared to Joying! Night and day difference!

2. I do miss the extra buttons on the Joying units, but i ended up re-programming most of them anyway -> power is now home, long power is shut down, back is app switcher.

3. I use Waze as the navigation app and I love using the "navigation" button on the steering wheel to switch between last app and navigation app back and forward. That way I switch between Youtube Music and Waze back and forward - I use T-Mobile Sync Up and Drive for WiFi hotspot.

4. Audio quality is quite good! Gotta adjust the EQ a bit but that was it. I have 4 speakers, 2 door subs (Mustang has subs from factory in doors), and a 12" trunk sub.

5. While the amp chip might be powerful, I doubt the rest of the circuits were designed for a higher load so it's not capable of driving too high of a volume, HOWEVER, it sounds a LOT better than the Joying+Pioneer combo I had prior.

6. HOLY MOLY, THE SPEED! It is SOOOO much better than the Joying unit when it comes to app install, app launch, app switch, etc. App install would take FOREVER on the Joying unit - they must have used some really crappy memory chips.

Overall. I have no regrets switching to this unit, even though I have a slightly small screen now.
[MTCD Android Head Units General] bogdi1988:
Here's my amp eq settings if anyone is curious.
[MTCD Android Head Units General] skezza:
We have the same unit (Albeit in different clothes). Scoop the mids some more. Honestly, mine sounds unreal now. I scooped the mids a bit, and boosted the trebles and bass and I've had people sit in my car and say "wow this is like a premium audio system". I laugh and tell them it cost **** all compared to a truly premium audio system. If you want me to post my settings I can?
[MTCD Android Head Units General] bogdi1988:
Go ahead and post them :) I will compare and test.
[MTCD Android Head Units General] skezza:
I am still tweaking, but this was my first attempt :) Let me know what you think :D
[MTCD Android Head Units General] bogdi1988:
I initially had the mids and lows similar to yours but at higher volume the bass was overpowering so I had to level the left half. Bumping the highs cleared out the audio significantly.

BTW guys, guess what I found? :) Xtrons updates site: https://xtrons.ibus-app.de/index.php?title=Aktuelle_Firmware
[MTCD Android Head Units General] Flemischguy:
After a lot of thinking and some mails with the guy of Android Auto Shop i pulled the trigger, very curious about the built in DSP in combination with Viper4Android. I surely will mount a heat sink wit a fan on 5 volt because that cpu can be quite hot, i bought a 7 port usb hub with 15 KV ESD immunity for in cars so i have the power of that hub, also for my smartphone, DAB+, TPMS, usb stick and some spare ports.
[MTCD Android Head Units General] bogdi1988:
Still curious what DSP chip is in
[MTCD Android Head Units General] Flemischguy:
i will take a picture of the board once i received the radio
[MTCD Android Head Units General] skezza:
Yep. I upgraded mine the other day. No significant improvement tbh.... must just be bug fixes. You have to apply the MCU and firmware separately. Not entirely sure which order you're supposed to do them in. I did the update.zip first and then the MCU. You'll **** your pants to begin with because you think it stops, it sticks at about 25% for like 10 mins. Then all of a sudden it flies up to 100% in the space of a minute lol :D
[MTCD Android Head Units General] bogdi1988:
I'll be doing mine tonight. I am kinda considering Malaysk also.
[MTCD Android Head Units General] Jkteam:
Still waiting for mine . Just wrote to them to have a update
[MTCD Android Head Units General] skezza:
I'm still yet to hear a cogent reason why Malaysk is actually worth it? All I keep hearing is "it's pre-rooted".... ok and why is that useful on your car stereo? ......"Because you can install xposed"....... ok and why is that useful on your car stereo? ............... "errrrm"

"...................."

"Reasons?"

Don't get me wrong I'm sure Malaysk does some very good stuff and has some very useful features, but I can't for the life of me see which ones are actually any use to the majority of people. The only thing I've seen that I wish I had on mine, is the ability to edit the steering wheel buttons, which is not possible on my unit because the decoder box handles it. Some addon for Xposed can actually do this..... Is it really worth a whole ROM for that though :D ?
[MTCD Android Head Units General] bogdi1988:
Viper4 Audio :)
[MTCD Android Head Units General] Superman0621:
Please let us know if you try Malaysk and how you like it I have been thinking of trying it.. It looks sweet...
[MTCD Android Head Units General] bogdi1988:
I was going to do the regular update just now, but it turns out my unit is at the updated version. I am still on the fence on whether I would do Malaysk or not.
[MTCD Android Head Units General] skezza:
Which allows you to interact with the amplifier directly? Once you've tried it, let me know. Like I said, if someone can provide me a decent enough reason, I'll happily flash it. I just don't see the point if it's just 'reasons'.
[MTCD Android Head Units General] bogdi1988:
I have used Viper4 before on the Joying unit. It doesn't necessary interact with the amp directly, but it's like a MUCH better EQ than the stock one. Can make a pretty big difference in the quality of the sound output.

IF these units actually have a DSP, I am assuming the EQ we have now is what it enables. In Joying the non-DSP units would have just 3 options for BASS, MIDD and HIGH so the quality of output was junk.
[MTCD Android Head Units General] ourson68:
Hello, I have this car radio, I have two bugs very annoying:

1) When I receive a call the sound is too loud. Xtrons support tells me to go to the "CAR SET" and change the volume. The problem is always the same.

2) using POWERAMP, and that I receive a call, I have conversation and music at the same time

Do you have the same worries?

Thank you all
[MTCD Android Head Units General] skezza:
1. Go into factory settings, I think you can adjust the volume in there.

2. I don't use poweramp. The benefits are far outweighed by the negatives.
[MTCD Android Head Units General] Superman0621:
Just updated mine.. as was said by someone else in the thread there is no major difference..but I always like to keep my stuff up to date.. still up in the air about trying Malaysk.. I always had my phones rooted ( until now damn moto z force lol ) but I am not sure if I see a point in rooting the head unit.. This thing is awesome as is.. So I will wait till more people try it and see if there is real reason to try Malaysk ...
[MTCD Android Head Units General] Jedimindtriks:
Yeah as a guy who has been through all kinds of headunits, i can tell that the new xtrons are good. Just ordered one from Androidautoshop.com with DSP, looks like the same unit but with a better soundchip

My ranking so far:

good:

Dasaita (overall best quality)

Xtrons Good allrounder

witson good with IPS monitor alltough this might be bad in the long run. unsure still. has ISO connectors which is good for Audi

(PX5 cpus in general)

Bad:

Erisin. (breaks after a few months) bad mainboard, the builtin canbus often times stops working.

Joying (unreliable) ****ty software

pumpkin (unreliable) ****ty software

eonon (unreliable) ****ty software

klyde (unreliable) ****ty software / bad mainboard

(all the allwinner cpu headunit)
[MTCD Android Head Units General] bogdi1988:
Hmm, I keep hearing of this mythical DSP chip... send us some pictures of the board so we can maybe see what's different.
[MTCD Android Head Units General] Jedimindtriks:
check the androidautoshop thread.

I was talking to a guy on chinarns and he told me about it.

its a hardware chip that gives way higher volume and much better sound. he explained it as having the same sound quality as the better known brands like kenwood etc.

So it looks like chinese units finally have good sound :)
[MTCD Android Head Units General] bogdi1988:
Link?

EDIT: NVM! Found the thread.

---------- Post added at 02:48 AM ---------- Previous post was at 02:44 AM ----------

[MENTION=8051679]Jedimindtriks[/MENTION] - looks like an add on board! Curious if they offer it as an extra - I will email them. Or if anyone can find the board online for sale and we can just solder it on the board. I am thinking the DSP software would get enabled kinda like the way the Joying units used to do...
[MTCD Android Head Units General] skezza:
Like I said in the other thread, have they compared to a current generation PX5? Don't compare to the nasty Joying units that have terrible chips. I would like him to try on one of the better units with decent amplifiers built-in. Volume is mostly dependant on the wattage of the amplifier, so do the units you speak of have a higher RMS output?

Some big claims suggesting it'll have similar quality to a Kenwood. That said, Kenwood have a cheap line of stereos and a high end line. I assume it'll sound closer to the cheaper sounding hardware. Regardless, any improvement over the audible garbage Joying units knock out is something. That said, Xtrons seem to be doing fine :)

---------- Post added at 11:26 AM ---------- Previous post was at 11:24 AM ----------

It's so mythical, there's no definitive proof that it even sounds better. I keep using the term snake oil, because big claims are only backed up by evidence and I've seen nothing to show these 'DSP units' are actually significantly better sounding than the built-in DSP's that you find on current gen PX5's knocked out by Xtrons (48w MOSFET tda7851 chipset).

One thing that is true, is they're a full £70 more (or 100$ in your case). That's not an insignificant amount of money and for that I'd want clear proof the audio is going to be better.

If the audio clarity is greatly improved, I suspect this will become the norm for these units :)
[MTCD Android Head Units General] bogdi1988:
Totally agreed on this! The stock chip in these Xtrons with a bit of EQ work is quite awesome!
[MTCD Android Head Units General] skezza:
Indeed it is. I was very surprised when I got it, just how good it was. I've had China 2Din's before. Many in fact. The first two or three I had, were just audio straight into the amp chip, so the only kind of EQ was the 3 level software jobby (BAS, MID, TRE) and the kind of tweaking is limited. The sound quality was also very mushy and a bit naff, but it was a tradeoff and a worthwhile one to get me the mapping functionality.

This Xtrons however, is the first one I've owned with a decent DSP and amp and the sound quality is next level. I think as people begin to purchase the newer units, the issues of sound quality will become a thing of the past.
[MTCD Android Head Units General] dmock09:
The only reason I would want to do it would be to have control over what programs stay active in sleep mode and which ones don't. Tethering my phone to the unit has to be done every time I get in the car because the program gets killed during sleep mode. But even that isn't a big deal. It's my only complaint with this unit at all. Everything else is fantastic for the money. Aside from tech support unsurprisingly.

Can someone check if bluetooth internet tethering from the phone to the TE706PL works.

Mainly use it for Google maps.

Currently have a Parrot Asteroid smart, looking to upgrade
[MTCD Android Head Units General] kilthro:
how is the display during the day or in bright lite? Is it washed out? Hard to see? I currently have a clarion nx706 and I hate the display as its washed out during the day and almost impossible to see in certain circumstance. Its also super laggy when changing the apps on it. I am interested in getting an android head unit and using an additional amp/equalizer to improve the sound as I am sure it's not going to be up to par sound wise as the Clarion has been. I am just concerned the screen is going to be crappy from a visibility stand point.
[MTCD Android Head Units General] dmock09:
Screen is surprisingly good in the day. I've never had an issue with it or thought it was hard to see. Tho it may different from car to car given various roofs and whatnot. Sound really isn't bad. I had a Kenwood before this and it's not noticably worse. Dial in the eq to your liking and you're good. Whatever the rated wattage is is a little optimistic but that's not too surprising. No static noises or alternator whines. Never had any interference of any kind.
[MTCD Android Head Units General] kilthro:
Thanks. yea i am sure they are optimistic with their ratings. that's why i will run a 4 channel amp to drive the speakers and process sound.. so no worries there. was thinking of doing an Android tablet anyways but thought this could need for most things i was looking for and saving time on compatibility. Just want a decent screen. lol
[MTCD Android Head Units General] Jkteam:
Hi

Just received the unit.

Can you elaborate? i really dont get it. If i dont use the m39 harness(stereing wheel control) i canjust connect the key 1 and key 2 cable? is so where?how?
[MTCD Android Head Units General] ItsMurf:
Yup, if you find the positive cables of each button (can be found with multimeter), just splice into those and connect to key 1 and 2.
[MTCD Android Head Units General] Jkteam:
and then everything will work? only with the 2 key 1 and key 2 on my steering wheel I have volume up down, seek up down for the songs , answer the phone (and mode when not using the phone) and hang up?

The main advantage of doing that is to have less stuff connected behind the radio right?Otherwise everything will work the same.

I have now i have the Metra Acces aswc for the steering wheel and i might just keep it since it might be easier for me.

with key1 and key2 and splicing can you reprogram and add functions like double tap or longpress?

Ok guys so I did install it.

By the way it's the one with DSP from androidautoshop

Well sort of installed it.didnt finish yet. pluged in with all the wires and back up camera basically just to see if it works

Didn't have time for the rest.will install external mic (will try internal first) GPS TPMS tomorrow.

I played with it a little bit . Obd2 connected to Bluetooth right away.

Tried the radio works well. Finding stations easily and the sound is good.(that's what I was worry about) didn't play with it for long time because installation took some timebut first impression very positive)

AndroidAutoShop DSP head unit

I have tried ordering the TE706PL from AndroidAutoShop, specifically as it advertises the built-in DSP. I was then contacted and advised that he needs to check with the manufacturer as there has been a delay in production, which normally takes 2-3 days but has been slowed down lately.

That was the last time I heard from the seller before he proceeded to cancel my order a few days later. I have not been contacted or had of my emails replied. I also did not receive a refund of the monies paid, which gave me no other option but to open a PayPal case, to which I am currently awaiting the outcome. From my personal experience with this seller I would advise to stay away.

Did anyone on this forum buy a DSP unit from this seller and if so do you have the pictures?

Anyone knows why this is happening:

First time a plugged the stereo radio was working fine.then later I start the car I didn't hear the sound.

I unplugged the harness plugged again it was ok

Since didn't touch the harness sometimes sound I can hear it sometiems no.

I can hear the sound of the buttons when pressing them for example volume.

Any ideas?

Got the TE706PL recently and built it in my Forester. All seem to work well, but one thing bothers me: I haven't found any app that can handle the volume setting. Only the native buttons and slider can change the volume. I use Car launcher agama as my launcher which has a huge virtual rotary volume button but that one doesnt change the volume neither.

Anyone knows what kind of volume this unit handles: system, media, ringtone, whatever.? i cant find it.
[MTCD Android Head Units General] smcabete:
I'm assuming you had to trim it. I already have that one with my asteroid smart. I did order another one just in case things don't work out I can just put my old radio back
[MTCD Android Head Units General] Jkteam:
Don't have steering wheel control?ifnno you can also buy a bleuooth steering control unit you just attach to you steering wheel

---------- Post added at 12:31 AM ---------- Previous post was at 12:20 AM ----------

The trim that you used for you parrot won't work with this unit.

Parrot is smaller.my trim was going around the parrot here I just need to add the top or bottom or both depending how I will fix it.on the side for me it doesn't require anything.

That unit it much bigger than the smart asteroid.

I had some doubts when buying the unit but after 1 week there is no way I go back to the parrot.

I will finish my install tomorrow.

Triming the ABS plastic trim was a pain in the ass since I wanted to put like 1 mm on each side but with a Dremel the plastic was melting too much when only 1mm

Now I have to decide if I put the radio in the center and palstix trim 2mm on the top and bottom or if I put the radio on the top of the double din and put 4mm on the bottom or vice versa.

My first choice is in the middle and 2mm on each side (top bottom) but it will be easier to just put it on the top of the double din and add a 4mm trim on the bottom.

Will drill holes tomorrow in the mourning bracket to put the stereo flush and since I guess the holes sont be perfect that will decide how much plastic I have to put and where
[MTCD Android Head Units General] smcabete:
I bought a"cheap" kit from Walmart and used a Knife to cut against the trim and came out pretty good. Unfortunately I didn't like the kit, so I ordered the Metra one. I'll be working on it on the 4th. I will post some pics of the trim kit
[MTCD Android Head Units General] shizuku:
I don't have steering wheel control indeed and i first like to explore everything in the unit itself before buying other stuff.

I also have no experience with Oreo, so a new opportunity to explore.

But the volume control bothers me; i cant figure out how that is controlled by the software.
[MTCD Android Head Units General] kPATm:
Iv been thinking about picking one of these up. Are they recommended? Im looking for somethimg that can stream from apps such as Deezer and similar. Also something that can be upgraded or better still put new rom images on. Thanks
