Anyone spot the radio chip in the picture's above? How difficult will it be to replace it? (maybe that's the problem with my unit)

Installed, I'll try it a bit later....
[MTCB Android Head Units Q&A] typos1:
That is a Klyde unit that was mentioned a few pages back :

I had not seen or heard of them before that post, the back is different to most of the units shown on this thread so far, deffo has an RK3066 processor though as we can see.

Couldnt you just return it and get a replacement ?

If the radio chip is soldered onto the boaard it will be a PITA to remove, if its connected with a ribbon connecter should be easy.

HuiFei - 2 DIN Pure Android 4.2.2 A9 Dual Core Car Stereo Radio Head Unit

Returning it will cost $150 minimum from South Africa, and then I need to pay customs on the new item (over 40%). I specifically asked the seller to check it properly because of this. I even asked in my mail after payment again that they double check before sending that everything is working :(

If it can't be resolved I'll have to claim via paypal, and lastly, my credit card company.

Radio chip is inside the metal box. I think the easiest way would be to replace the entire radio module.

In my unit is that one QSD-RT-L93

[MTCB Android Head Units Q&A] RoLoYYZ:
Bought a unit from Keylo, I had it installed for a week before the sound started doing some really odd things, right at the start of a long 8 hour trip to Michigan. The sound would play with a high pitched squeal, very slightly initially. Then louder and the sound cut out from the front speakers. Then eventually the rear. Now if the sound plays, its for maybe a minute, muffled, from the rear speakers. Then it goes to a very loud squeal or nothing at all.

I'm in contact with Keylo, they mentioned sending a new amplifier IC. I sure as hell hope it's in a socket and not soldered on, as that would go beyond my skill level. I see others receiving parts from them, have you had to pay for shipping? That seems a bit ridiculous considering I've had the unit for 3 weeks, 1 week before it started flaking out. What have peoples experiences been with their support and end result?

[MTCB Android Head Units Q&A] kvantum:
About f$%*ing time a proper tech company addressed this

Carputer as a somewhat working concept has existed for at least 10 years now, and ever since the first iPad came out people have been hacking tablets (physically hacking, not necessarily in software) to work as a car gps and entertainment platform.

Looks like your phone is the guts, and the head unit just mirrors the screen. This means Android Auto would have to be a standard app or even part of next OS version. Therefore, as long as we can upgrade our head units, or install APKs, there's no reason why we can't eliminate the phone entirely and just use this new feature directly on the HuiFei unit

[MTCB Android Head Units Q&A] Niolin:
Volume Controls

My unit (running the as-shipped ROM and MCU) only seems to have 1 volume slider which adjusts all volumes. However, the 'radio' app is significantly louder than everything else, so if I switch from radio to bluetooth or Pandora I end up needing to punch up the volume, and going back to radio I tend to blow out my eardrums.

Is there anything that can be done for this?
[MTCB Android Head Units Q&A] giornistrani:
Hi Malaysk. The problem on the audio depende from file update.img or mcu.img? thanks
[MTCB Android Head Units Q&A] Malaysk:
And what problems with the audio? If the radio sounds bad it depends on MCU.img and it is necessary to open the device mechanically and solder capacitors

Power management

Regarding standby modes, do you guys think we can ask Klyde/HuiFei that they include proper standby modes (not that 30sec thing), I don't know how well they respond to that kind of requests, nor where to find the contacts (does somebody have them?).

Maybe we can do it ourself, when my unit comes, i'm compelled to open it up and research for an opportunity for hacking a semi-standby mode, because I have skills in bare-metal microcontroller programming. My plan is to find the components that consume most of the power (like display, radio module, power amplifier, basically all but the android unit itself), then put an mosfet to control their power, and put my MCU between ACC from car and ACC on headunit, so when ACC signal goes low unit wouldn't come directly to poweroff, instead it would come to semi-standby, and after programmed time (lets say about 2hrs) it would actually put ACC signal on the head unit side to low, so it would complete its normal poweroff operation.

Another mod would be when the car is off (ACC low) that when you press the power button (longer press), unit would power on.

Mod complexity depends on the motherboard complexity. Of course I would share this with you. :)

What do you think?
[MTCB Android Head Units Q&A] Marius B:
How make that ?
[MTCB Android Head Units Q&A] Niolin:
If you could do this, that would be outstanding. I think that a proper low-power standby state (with a 5-10 second return time) is sorely missing in these units.

You can find all the manufacturers on Alibaba and Aliexpress.

Yes, download the KGL image and extract it - its the KGL launcher.

Why are you trying to open it ? !!

As the first page (and countless pages since, including several posts in the last 10 pages) says, you just put it on the root of an SD card, put it in the GPS slot and it should auto ask to update, if it does not do it from recovery. Have you read the first page ? ! :)

I have a KLD unit and have a few questions:

Is there a way to switch off the screen but keep the radio playing?

I notice when forcing a hard reboot after installing a xposed module, or say if I hold the power button for 10 seconds (which then goes into recovery), the radio presets are reset....is this normal?

Is there a way to trigger a normal reboot? Where it shuts down first and then reboots?

I have a usb stick connected with my music. When I turn off my car the head unit starts powering down but just before that I can see the "storage unexpectedly remove" message in the status bar. Not sure if this is going to give me issues on my usb stick in the long run - so is there a way to have it safely remove first when i turn off the car?

I wish there was a happy medium between cloudu's rom and malaysk's rom. Cloudu's is great because it's super snappy and there's no lag. Boot up is faster too. Malaysk's latest rom has been a hair sluggish for me, but it has a lot of great options out of the box and the UI skin looks a lot better. If Cloudu's rom could just have Malaysk's UI skin, be defaulted at 180dpi, and come with Titanium backup and MTCService already installed, it would be a great package.

Hi [MENTION=3590033]Malaysk[/MENTION],

Im running on my KLD your last ROM (25th April, regular launcher) but I got some little problems:

At the first start, in order to go back from Music I got the error: " app Start stopped working" (don't know exactly if this is the right translation, in english), this is not a very bad problem I press ok and that's fine.

the other one is the Music it doesn't keep playing the last song, which was playing before switching off the car. It doesnt do it always, just sometimes :)

I installed this ROM on the old one (3rd April), as soon as It started I reseted everything. (I followed your guide)

Backup camera issue

Yesterday I started having a strange issue where the display would cut out and the sound would get attenuated. I believe it's the unit thinking the backup camera is active but since I'm not in reverse there's not video feed to display. I've got a KLD unit with the latest (2.49?) mcu and rooted Android rom. It just started happening yesterday, I've been running the current software configuration for weeks now no issues. I'm assuming the reverse signal is decoded on the head unit from the OBD adapter that was included? I'm not sure if a loose connection would account for this issue and I'm not looking forward to taking the system apart to find out (since it would void my warranty. Any ideas?
