I got the seller to get me a pick of the back of the NaviFly unit with external Can Bus (attached). Does it appear that it will help with the fitment issue?
[MTCD  Android Head Units Q&A] doctorman:
contact carjoying

there is daily update on mtcD ROM

latest update was april 30 both mcu and rom

---------- Post added at 10:55 AM ---------- Previous post was at 10:51 AM ----------

I tried to get joying to cover the cost but they are scared of the confusion out there with Malyask ROM.

they said many customers installed Malaysk ROM on mtcD and bricked it.

Any how we are moving forward with collecting donations. I will send him one with DVR as soon as we have enough to cover the cost.

donation link in my signature is just for malaysk mtcd unit.

It alao lacks the rear USB ports also, I need to decide if that is important to me or not
[MTCD  Android Head Units Q&A] hadeone:
Are you sure? They are probably on an external cable. Check the pictures of all the harnesses that plug into the unit. I thought I saw some USB female sockets on there (purple plug).

[MTCD  Android Head Units Q&A] The LT:
I have this exact unit. (Even the warranty stickers are the same). There are two external break-out USB cables which attach to the rear, one marked "3G/WIFI" and another just "USB". One is supposed to be used with a 3G/4G USB modem and another with USB storage or DVR front camera. When fitting, I had to cut a small hole in the air duct for radio antenna so it would fit on the left side. Other than that, no problems so far.

Really? Does it work? What version of twrp? How did you install it?
[MTCD  Android Head Units Q&A] tpf:
I actually used Nandroid backup to make a TWRP backup.
[MTCD  Android Head Units Q&A] just_bol:
For what? Without twrp recovery it's useless (IMHO).
[MTCD  Android Head Units Q&A] TT_Vert:
I tried to restore a nanroid online backup in TWRP and it doesn't even work. I have a post on it somewhere. If trying to make a backup via TWRP you'll see 0mb for data which clearly isn't right. Then when you restore it you just get a boot loop.

Of course. I do not need this device. It is not suitable for my car. I bought it purely to modify the firmware. Personally, I do not need. I think .... Joing need for large sales. But he is not interested. It is sad. I think all this will stop. Why do I have to raise their sale at their own expense ??? I have nothing against them ... I'm just trying to help people in solving problems. I think it is necessary to return the $ 104 and close this topic.

If he gives the word he'll proceed w/ 5.1.1 i"ll surely donate. Question is, will other devs follow suit? Apps like headunit, xposed, other MTC apps, etc. need to work as well.

Dave
[MTCD  Android Head Units Q&A] doctorman:
I offered to get him the mtcD unit from Joying at cost price and through in a DVR so he can also improve the DVR app.

Unfortunately Joying is not interested in the custom ROM. they say it confuses the people and many customers mess up their head units with custom ROM and come to them for support.

I am still doing it at cost price to myself as Joying is not donating it.

Also Joying is not the only company who makes mtcD. There are others who would enjoy the sales increase.

I might just cover the cost of the unit and only release the ROM to the Donors till the full price of the hardware is reached. This way the Donors will get what they paid for and Malaysk gets to work only with people who appreciate his work!

So we might make a VIP club for mtcD Malaysk ROM if the cost is not covered soon.

---------- Post added at 01:07 PM ---------- Previous post was at 01:06 PM ----------

as more and more devs get mtcD there will be more development.

I can guarantee that Malaysk will get one regardless. the question is who will get access to the ROM. If we do not have enough donations.
[MTCD  Android Head Units Q&A] Marius B:

[MTCD  Android Head Units Q&A] sterod:
It's been said that Malaysk will TRY if he gets the unit, no guarantee of success. Think of it as a Kickstarter.
[MTCD  Android Head Units Q&A] TT_Vert:
There is already root access so I don't see why he would have any issues what so ever.

Dave
[MTCD  Android Head Units Q&A] sterod:
I'm no expert so I can't comment on that. I donated with the understanding this may or may not be possible.
[MTCD  Android Head Units Q&A] Malaysk:
I think everything is going to be alright. I will close the device :)
[MTCD  Android Head Units Q&A] Samoawbc:
This devices are so "new". I would say give people a little more time and i'm sure you will get enough money to buy one.

I just order a 5.1.1 unit today. If its arrived and i'm overall satisfied with it i also provide a little bit money.
[MTCD  Android Head Units Q&A] doctorman:
YEs Malaysk is very committed to make the ROM for mtcD. people need to show their support. not a single donation for a week now and that is embarrassing!
[MTCD  Android Head Units Q&A] Pattond:
I will donate if I wind up getting a 5.1.1 unit, Joying does not make the next generation unit for my e46, so I am limited to Erisin or NaviFly at the moment. I am holding out for one of the builders with better support for my car upgrading their e46 offerings (Avin or Eonon)
[MTCD  Android Head Units Q&A] doctorman:
I agree with you guys.. may of the models are not upgraded to the mtcD hardware still.

Joying is working to update all of their models but it will take weeks.

the 7" units should be easy upgrade the 8" units have not had the upgrade for the screen. the screen ribbon cable is different so just changing the motherboard and core is not enough.

Again as the mtcD gains popularity I am sure the development will catch on.
[MTCD  Android Head Units Q&A] The LT:
I am quite happy with my GS unit for the E46 actually. The MCU isn't giving any trouble. Bluetooth comms work fine, rear cam too. Just saying.

[MTCD  Android Head Units Q&A] tpf:
Radio reception on my Xtrons GS unit isn't too bad with the Audi rear window (amplified) aerial.

The radio units selectivity is dubious! It does suffer a certain amount of breakthrough from various external sources, such as pager towers. I can't say how this compares to the original Blaupunkt unit as I didn't do a side-by-side comparison, and almost any mobile radio will suffer somekind of breakthrough.

Soundwise, it lacks a little punch and the equaliser needs some careful adjustment.

I've tried an SDR dongle with Wavesink for DAB radio and the sound quality is excellent.

Hope that helps :)

Somehow, Joying still can't upgrade the 7" unit that without the panel button at the moment which I'm using now. look like the internal connector also different from the button type.

I think this community is far better than most resellers support sites!

tpf
[MTCD  Android Head Units Q&A] TT_Vert:
100 times better. You should see the disaster of support Joying has. It'd be quite the comic relief if I were to post up the emails back and forth. There are only so many ways someone can say " the unit will not go into recovery" and "I am not disassembling my car (or a friends car as they suggest) to put in a DOA unit". It's not going to work just because the 12vDC is coming from a car and not my regulated power supply.
[MTCD  Android Head Units Q&A] tpf:
I'm facing the same thing with Xtrons! They just don't want to deal with the issues, ie things I need changed to get the unit working to higher level.

Simple things, like fixing the name of the internal and external sd cards so they're usuable by apps.

I also had my unit on a bench power supply before installing, and will remove again for the new firmware ;)

Do you know if I can make a useful backup of my MTU/firmware or does that have to come from the reseller?

[MTCD  Android Head Units Q&A] TT_Vert:
Can't help you on the xtrons, the joying FW/MCU's are all over the internet. The biggest issue is i reply to something and then two days later i get the same reply then wait another two day for them to ask me to do something they originally asked for and received. It's just an endless process.

[MTCD  Android Head Units Q&A] w0rdie:
TT - You're attempting to boot from cold start to recovery correct? Not reboot - ?
[MTCD  Android Head Units Q&A] TT_Vert:
I'm just attempting to get this unit to boot at all, no video. The LED's flash. Joying stated it was a bad board of some sort originally and said to send them a $50 deposit and then to ship the old board back to them in China at my expense. Uhh, no!!! So then they told me to put it in my car or a friends car. Uhhh, why would i disassemble my, or a friends car, to put in a unit that clearly isn't working. So then a week goes by and they again told me to go into recovery apparently (conveniently?) forgetting that a week prior I sent them a video, showed them I could not get into recovery and their own tech said I had a bad board of some sort. So here we are nearly two weeks after receiving the unit and having no real resolution other than sending them a deposit then shipping back their junk bad part on my dime. So my $250 unit now ends up costing me $275 plus and a bunch of my time to disassemble replace the part, box up old part, go to post office and wait in the long line and ship it back while figuring out how to fill out the customs forms. Yeah right joying..

The real ironic part of this is that I bought this unit directly from them after having THREE units from amazon being defective. Two had cracked screens and the most recent one was used, still has the users information on it, has modified circuitry, software, and a harness that is cut so short it'd be hard to use, etc. It's shocking how they are still in business. Maybe Americans are too demanding??

Dave
[MTCD  Android Head Units Q&A] w0rdie:
Whoa.. thats a horror story. Had you replaced the stock recovery before things went south?

Good luck and keep us posted how things go as you work through this.
[MTCD  Android Head Units Q&A] TT_Vert:
On this newest 5.1.1 unit I did nothing other than take it out of the box and connect it to my 12V power supply. Knowing the QA with these guys I know not to disassemble my car, install and know it will just work. I connect a speaker to each output, test GPS, microphone quality, etc. before it goes into my cars. I've put these in most of my cars, one left and it's being a fighter, well joying is actually. I emailed them on 4/30 asking how I could get into recovery on this unit thinking maybe I had a SW issue and they've yet to even reply to that email lol. Maybe this is one of those screens you need special glasses to view?

Dave
[MTCD  Android Head Units Q&A] TT_Vert:
It's not only a few dollars, as stated in our private conversation it isn't about the money either, but more on that later. I purchase only amazon prime. All units are stated as new, not used units. I pay full price on amazon for new units.

Truth be told if I was aware of you before any of this I would have gladly purchased from you but the only way (at the time) for me to get a 7" screen 5.1.1 was via joying direct. Amazon ETA was in June. Again had I known what I know now.... With that said i"m lucky to get one email every other day and I"m even more lucky if the email doesn't a. tell me to do something I was told to do multiple days ago and told them was already done or b. tell me to do something they know isn't going to fix the problem (I believe in the hopes I'll just give up and go away out of frustration). Just because other companies don't reply doesn't make up for joying's lack of "effecive and logical" technical support. If all companies w/ sub standard support compared themselves to only the worst companies for tech support where would we be? Fortunately that isn't how things work here state side. We expect more yes but we also pay more for it, therefor we expect to receive what we paid for FOR what we paid for it. I'm not blaming you at all for my situation and I appreciate your efforts to help. With that also said, I'm not sending them a $50 deposit AND paying to ship a defective board of some sort to china or anywhere else at my expense. That is not acceptable and I'm fairly sure anyone here would agree with me on that. Like I had said, my time is valuable to me and quite valuable to my customers. For me to spend an hour boxing this, driving to the post office, standing in our long lines, then being sent back because inevitably i fill out the wrong customs form then driving back this would be a $200 plus bill to any of my customers. So this request is not only unacceptable it is almost extortion. (Do as I saw, how I say it or you have no working unit). Thanks for replying but my situation here is not unique as i've read before and your attempt at damage control, while admirable, is putting a band-aid on a gunshot wound.

Dave
[MTCD  Android Head Units Q&A] TT_Vert:
And right one queue, three days w/ no reply and I get an email today with them asking me to put it in my car again to test it. Despite me sending them an email 4 or so days ago telling them I did put it in my car and it didn't solve a thing. Of course putting it in my car isn't going to change a thing and everyone knows this. This is just my bi weekly comic relief at this point. I'm curious how long this can go on for..

[MTCD  Android Head Units Q&A] Pattond:
Between the differences in language and culture plus the difficulty of communication in time zones across the world, i'm not sure that any of vendors are capable of the level of customer service we see here in the US or in Europe.

When you were looking at the best of the Chinese android head unit manufacturers, Joying, Eonon, Erisin, Pumpkin, and look at the others who have nearly no support I am not sure there's much difference at the end of the day. I'm sitting on the fence before purchasing trying to figure out how to minimize my risk, not monetarily, but risking the time and effort people like you are having to exert just to get you to work basic functions.

I would be more than willing to pay more money to get a unit with the build quality of a Pioneer, Alpine, or Kenwood, but the features and OEM appearance of these units offer
