Thanks shadowmike, you are right the 2 screws were not removed, so removed them and CD is working now.

Now, the last 2 things are,

1: anyone figured bluetooth audio streaming?

2: My car is a 2011 Camry, the unit I have has CAN Bus TX and Can Bus RX. so how do I connect it to the car? or I need an CAN bus adapter?

thanks

[Android Head-Units] HaroldH:
Hey there donald. I have a 2013 Chevy Tahoe and the pac-audio instructions use the "green wire" from their SWC adapter to attach to my vehicle rather than their "white wire". Can I still connect Key1 to that same location in my vehicle or does PacAudio's instruction of "green wire" mean I need to do something else? (NOTE: the Pac instructions also indicate that I would need to cut their brown loop wire) Logic tells me that "green wire" and "white wire" would NOT be the same, so I thought I'd ask for help to see if there was an equally simple hookup solution.

I've tried to be a good citizen and I've searched this thread for everything from Canbus to SWC to Key1 and 2, high low, Tx Rx etc and your post above seemed like it might provide the most direct solution to my question. Thanks for your help.

EDIT FOR 2nd QUESTION:

I had also looked up my vehicle on the Axxess website. On the Axxess site, it has a single pink wire (digital?) hooked up, but to a totally different harness/plug/wire in my Tahoe. With the Axxess, it's connected to a single wire right behind my head unit. With PacAudio, the instructions would have me connect their unit to a wire/plug that's up under the steering wheel. Any idea why there is a discrepancy between the two? Different methods of communicating or tapping into the same info at a different location?

FINAL EDIT of additional info

- The headunit I have is the 6.2" AN-21 U that looks exactly like the one in the very first post of this thread.

- I found a GM wiring document that indicates pin13 of my head unit harness is "Low Speed GMLAN Serial Data" This is the pin that the Axxess SWC unit would connect to.

- I also found pin-out guide that indicates my OBDII interface pins 3 and 11 are for "MS-CAN (+) (95kB)" and "MS-CAN (-) (95kB)" respectively. It also shows that OBDII pins 6 and 14 are for "ISO 15765 HS-CAN (+) (500kB)" and "ISO 15765 HS-CAN (-) (500kB)" respectively. This online "info" is unverified by me, but is there some way to interface any of those OBDII connections with the Android headunit's CAN Tx and Rx connections to get SWC, or would that be barking up the wrong tree?

Thanks

Has anyone been able to identify the system version of this update from Peter Chan yet?
[Android Head-Units] Zittermann:
I think the CAN Tx and Rx lines from the head unit can connect to something like the MCP2551 CAN driver. I have not tested this, but I will order some of those drivers and give it a try.

If this is correct, the pins 6 and 14 from your OBDII adapter can do the same as mentioned in the datasheet of the popular ELM327 chip: http://elmelectronics.com/DSheets/ELM327DS.pdf

Those infomration are speculative. I hope there is a way to get around of buying a CAN Adapter from Dietz...

Thanks for the reply, Zittermann.

For the 2013 Tahoe, I'm already going to have to buy a 3rd party interface to maintain OnStar and door-chimes but I was just hoping I wouldn't have to also get a 3rd party unit for steering-wheel-controls too. The CAN Tx/Rx lines were a longshot, since it seems that most people with the AN-21 U are not tapping into them, but I'm open to any options. I think the best scenario for me would be if I can wire directly from my auto's wiring into the head-unit's Key1 or Key2 line for SWC, but I'm just not sure if that's an option or not with my particular vehicle.

Sorry it took me a while to reply. I've been super busy at work and they released an unlock for the HTC one M8 so my focus has been a bit off :p

The unit came with 2.6.73 and the preinstalled MCU was 4.2.6-1-10-2101, A "model choose" (V4.2.6, RDS, Sleep, Color, Rohm37534, TEF662

x) switched it to 4.2.6-1-10-2301

Sleep does not seem to work as is, didn't really do much else. I'm waiting for some molex connectors to hook up my usb cables as they've changed it on me (see hardware thread) haven't rooted yet so I can't tell you what other MCU files are there, but I'll check before I update. Sorry, don't really know when though as this "work" stuff keeps dragging me out of the house for days at a time...
[Android Head-Units] shadowmike:
When you get the usb connectors let me know if mirror cast works. I have the m7 with a m8 port Rom. But choosing mirror cast does nothing. I have not looked into it yet. I know it will be probably impossible to actually use the feature on our radio

If it came with .73 you have older MCUs on it.... I am hunting for the new .96 ones coz knobs mirror and direction change take affect.

Even the shutdown delay works now.....

I could already test all with other MCUs from .96........ but they dont fit to my Front Plate so everytime something not working like BT or Knobs

Looks like it's been asked a few times, but can't find an answer.

Is there any app that might be able to help with gain or sound quality out of the microphone? Voice searches are still very hit and miss with me.

I have a unit that came with an external mic connector, but no mic I plugged in could generate more than a whisper. The built in mike was marginally better so I disconnected and soldered my own mic connector to it's connection on the board.

Sounds better than I've had yet, but I still struggle to get voice commands recognized. The mic bubble on Google Voice search jumps around like I'm in a noisy crowd even when the car is off and there's no other noise.

I also tried this http://www.bhphotovideo.com/c/product/898863-REG/MG_Electronics_pa_3_PA3_12_VDC_Mini.html

amplified mic, and while it is awesome for phone calls, voice recognition doesn't work at all unless the car is dead quiet and I speak very softly. So I'm thinking of finding an inline 3.5mm volume control to tone down the amped mike, but any other suggestions would be awesome.

I checked the stock pictures and it looks like they should have the holes. But I'm curious, has anyone heard of any universal mounting kits that don't use mounting holes?

Folder permission problem

Hi all, I'm experiencing a big problem, all folders except externalSD have the "read only" permission. All apps that need to write its configuration on such folder are giving errors or they say there is enought free space...

This started to happen with 2.6.70 and also after updating to 2.6.96 system version.

I have root permission, but I cannot modify folder read/write permission anyway.

I cannot install APKs because the installer have Install/InstallSD buttons disabled.

I've noticed that sometimes after startup these folders have correctly write permission, but this occurs apparently randomly.

Is there a way to fix these folders permission problems?

[Android Head-Units] PsychoMcSatan:
I've never seen a video-RCA (yellow) cable with an extra red wire sticking out, but I think ground is a good guess. You can double check that it's ground with a multimeter as the outside of the cable connector is ground as well.

As for the power, yes you can wire it to the reverse light so that it's only powers on when you're in reverse. However, I've wired it to my ACC power so I can put it on while driving forward as well. Constant power from the main battery line is not a good idea as it'll slowly drain your battery.

[Android Head-Units] Sopiva:
Hello everybody.

I need some help. Since day one, my radio has not remembered any audio settings or radio channels after not using the car. I have triple-checked the wiring and there is no problem with them.

I read that there was someone with similar problems here too. I did not find a solution though other than installing 2.6.60-2, then 2.6.62 and then 2.6.70. Unfortunately I can not do this as my stereo came with 2.6.70 out of the box, and the system does not allow me to downgrade. It just says "update start" and then after a while goes back to the menu.

I was able to update the stereo to 2.6.77-2 but no help from there.

Any ideas anyone? It is really annoying to browse the radio channels every time you start the car.

Here is where I am now (with 2.6.77-2, others are unchanged)

[Android Head-Units] KID52:
It's not for ground.

You connect one end to the stereo "REVERSE" wire, and the other end to the reversing light positive so the camera automatically displays when in reverse.

It's a fairly common design, and means you don't need to run an additional wire for the reverse signal.

I ended up having to connect Key 1 to one of the slots and ground key 2 to the black wire on the stereo harness. Just offering some input in case you run into some difficulties.
