Ford Bluetooth

Hi
first thanks to mfrazzz for wm6r5 which I am using...great stuff. And to rest of guys for such easy instructions
Has any one any suggestions as to how I can get the phone to bond with a UK Ford Mondeo ? It finds the car when setting up a partnership but the car never recognised the phone has bonded with it. Seems there are some comments around about the Nokia software in the car but no answers.
Suggestions on other bluetooth stacks I could try on the MDA (UK T Mobile) ?
Cheers

PX5 4GB RAM 8 CPU-what HU with good bluetooth call quality and working ok google

Hi Guys,
I am pretty familiar with these HUs. However, I have a question that I don't know if there is a definitive answer to.
Question: Is there a PX5, 4 GB RAM, 8 CPU cores, Android Oreo headunit that has good Bluetooth call quality and has mic working outside the Bluetooth app flawlessly?
- I have seen some HUs with exceptional call quality (XRC MCU with BT chip SD-968 for e.g.) but the mic would not work outside the Bluetooth app
- I have seen some HUs with mic working outside Bluetooth app but has terrible Bluetooth call quality (HUs with BT chip MD 725 for e.g.)
What I am looking for is the MCU, Bluetooth Chip combination that gives the expected result. Of course the latest HUs with PX5 board, 4GB RAM, 8 CPU cores and Android Oreo OS
Thanks in advance!
Cheers,

They don't exist in hassle-free quality.
BT audio quality in my experience isn't at the same level of branded or OEM.

Yeah, that is what I understood from various threads in the forum as well. Mine is the XRC MTCD/E unit with BT chip SD-968 and I have to say that the Bluetooth call quality is fine; but then mic doesn't work outside BT app.
@twist has purchased a new PX5 unit and he was telling that the BT call quality was "good".

My JY and from experience with GS and HA all have functional Mic outside of BT. e.g. Google now, search etc.

But the BT call quality was scratchy with those units?

The sd968 on the HA unit I installed for a friend appeared to have acceptable audio with a quality external [mic] fitted. It had a proper onboard mic input that actually disabled the internal - without mods. Other end reported no echo while maps was navigating. My
This isn't an endorsement for any particular product., Just sharing some experience. At least HA share regular updates from HCT and on the other hand haven't progressed fixing bugs such as A2dp or BT issues - despite change logs.

Subwoofer Seat Sound not working

Hi all,
I have a Seat Leon 5F with Seat Sound (so including a subwoofer). I've just installed a Witson PX5 W2-V5570 Android 8 unit. It's working fine, except for subwoofer (not working) and probably also center speaker.
On the original system, the signal for the subwoofer is coming from the quadlocker, but this doesnn't seem to be processed in the Android unit..
Anyone familiar with this? Know a solution?
Many thanks!

I'd say cut off the wire and solder it onto the extra cable used for subwoofers. But I'm not sure how the connections on this device are

Hello.
Do you still have your head unit ?
Thanks

Yep, how so?
I intend to sell it though. It works, but i cannot get the sound to work properly. I have sound, but it appears it cannot drive all speakers from seat sound.

old px3/px5 upgrade, newer 8.1/9.0 units - Too many questions!

Sorry if this has been covered already, or if I'm posting in the wrong area.. my brain is melting do to information overload.
Long story short, questions after:
Currently running px3 1gb, 5.1, with bt/wifi issues. I had used a usb-ethernet dongle hooked up to a Asus 330GE portable router in bridge mode. BT Connected and fast network. Woot.
I'm going to be giving my car to my sister, but I feel like the px3/1gb would be dangerously slow. (Keeping android HU for the backup cam I have wired.)
Questions:
1a. There are no bt/wifi chips that can replace (soldering) the current chip to fix the wifi slowdown issue - correct?
1b. Disconnecting the internal module and using USB dongle = same issue - Correct?
1c. Is this because of a USB hub issue I think I read about?
1d. If you have a type2 md725 module, BT does not connect with 8.0 at all, but a type1 can be connected in order to use 8.0, with the wifi-slowdown-when-bt-connected issue persisting - correct?
1e. (bonus) Are there type1 md725 usb dongles?
2a. Do you think a px30 2/16 core board upgrade would be sufficient (not slow as molasses) for basic simultaneous navigation + a2dp/radio/internal player ? (leaving out the assumption that the bt/wifi issue would persist. Talking about system speed wise)
2b. Do you think it would be necessary to bump up to px5 4/32 for $50cad?
3. Why do some of the new DSP eq's show a frequency adjustment low of 25hz, and some 20hz?
4a. What's the deal with these Android GO 8.1/9.0 1gb/16gb units? (I doubt I'd go this route, but just curious.)
4b. Wondering if this 8.1/9.0 GO could be ported to older p3, or p5 2gb units?)
5a. Does the bt-connected-wifi-slowdown issue still remain with these newer p5 units?
5b. Is there a simple way to confirm this other than msging seller for usb hub/wifi/bt specs?
These seem to be the best prices I could find for possible solutions:
*$117ca px30 2/16 Witson coreboard
*$165ca px5 4/32Witson coreboard
*$275cad 4/32 without DSP
*$320cad 4/32 TDA7851 + ST7786
First choice, thinking of upgrading to the px5 4/32
Would like to save 50$ if possible by using a px30 2/16
Would like to save all the monies by somehow convincing humans greater than myself to port 8.1/9.0 GO over? (assuming this would be quick enough)
*!HeadEsplode!*
When I do get this sorted (new(to me) vehicle acquired, current vehicle to sister,) I will most likey be going the 4/32 px5 DSP route, or possibly px6. (or Intel?) (Headexplodeagain!)
Hoping someone out there can steer me right ...

PX6 upgrade
I have the same set of questions, but also would like to add PX6 board in the list. Does anyone tried upgrading PX3 to PX6 on MTCD board?

I'm not sure, but I found this on another thread:
" yes, you can use the updates listed as PX6 (as they show PX5 once you download them). "
linking to https://forum.xda-developers.com/an...asaita-mcu-updates-rockchip-px5-octa-t3575155
I'm thinking yes. Have you seen any px6 coreboards for sale yet? Maybe there will be a group buy ..

Just to tag on and answer some of OP's questions as I'm in a similar situation:
1.d - You're correct (from all the reading I've done too). There's type 1 and type 2 MD725, with type 2 not working with android 8.0 due to driver issues.
1.e - There are usb dongles with Type 1: Comfast WU725B. This apparently solves people's issues.
2.a Although the PX30 should be better in terms of speed, I'm pretty sure you will still get a bit of lag with navigation (generally loading things up) but otherwise ok once running as long as there isn't too much running in the background. That is just an assumption as I don't have any experience with a PX30...but I do own a PX3 with 2GB RAM which is meant to be slightly worse than the PX30.
2.b. You'll be better off getting the PX5 if you're doing a coreboard upgrade anyway...I regret to not going the PX5 route from the beginning.
Now a question for everyone else:
I'm looking to upgrade my PX3 (2GB/32GB) with a PX5 coreboard. It appears only Rev8 PX5 Coreboards are available now which come with android 8.0 and the warning about Bluetooth and wireless potentially not working (which we know about MD725 type 1 and 2).
However my MTCE unit has Bluetooth module SD968 (with a separate wireless card) and I can't find any mention if I will have any problems if I upgrade the coreboard.
Does anyone know if the SD968 works fine with Android 8.0 PX5 coreboard?

Yes it does. That is the combo that i'm running in one of my radios.

Perfect! Thanks for confirming that. Guess there's nothing stopping me now, unless a PX6 board magically appears lol.

What do so have?
Hi there,
Sorry to open an old thread.
I have been reading up for ages but can't identify what MCU I have, is anyone able to tell me from the pictures or do I need to physically take it out and check?
Thanks.

anybody know where i can buy px5 or px6 core board? xtrons want to sell me the px5 4/32 for 150$! it is too expensive!

Hi, I have a px3 board with mtcd software and want to upgrade to px5. My board has a md725 Bluetooth chip installed so could anyone advise me on a suitable upgrade path as the 1gb of ram is killing me ha many thanks!

Hi, I have a px3 with md725 bluetooth on mtcd software. I would like to upgrade to a px5 board so could anyone point me to a listing which I can purchase from that will work? I dont want to lose any functionality of the Bluetooth/WiFi so I'm not bothered if it's running on android 8 or below or 9 if possible. Also should I upgrade to mtce first or after upgrade or does it not matter? Many thanks

Xtrons PQS1139BL issues

Hello, I purchased an Xtrons PQS1139BL and it's been a toxic relationship. I love the features but its very buggy. Xtrons says there are no updates for this unit and I think they are tired of dealing with me.
This is my bug list.
Every electrical noise came out the speakers such as alternator whine, the idle are control valve on the engine, turning the headlighs on and off causes a pop. The solution so far has been Xtrons sent me a filter that removed 75% of the noise but my wife still could not stand riding in the car so I gutted the factory BMW DSP and added my own 4CH amp the is ran off of the RCA cables and that resolved 99% of the noise. But this unit only has front RCA out so now I lost fader control.
Unit lockups about 1 to 2 minutes after starting the car the UI will freeze and what is on the screen will stay but the steering wheel controls will still continue to beep when pressed eventually the screen will turn black and the steering wheel controls will stop beeping then sometimes the unit will reboot and come back and other times I need to restart the car at a red light or pull over and restart. My wife pointed out that it mostly happens after I reverse which lead me to this forum and as an experiment I cut the reverse input to the headunit and now the lockups after starting the car went from 50% to 5% but now I lost my backup camera. One thing to add is that once the unit is up and running it works fine so I don't think it's a heat issue.
Wireless carplay, the unit came with an app called multiplay and half of the time it would say "MFI chip not found". So Xtron's sent me USB adapter that uses an app called autokit and that works okay but my phone shows that it's charging but it's actually loosing a charge so I bought a USB Y adapter to add power from a cigarette lighter plug.
The versions that my unit shows is
Model PX6
Android 10
Build number rk3399-userdebug 10 qq2a.200305.004.a1 eng.hct2.20210630.152440 test-keys
Kernel version 4.19.111+
#131 Thurs Jun 24 2021
MCU version MTCH_GS_V3.78_3
May 31 2021
Is there any hope for this? Can i update it? Can I wipe and reload it? Can I pull logs off of this? I'm about over it.

I resolved the noise issue with an aftermarket amp and the locking up i patched it with a switch in the glove box to reboot the headunit manually. That's the wifes job. This xtrons unit is complete junk.

Xtrons, complete junk. Yep - fake Chinese origin brands that sell from various factories at their best margins (buy cheap, sell expensive)
