I have a problem, may be any of you can help me because i'm out of options. I installed spotify and due to some sound priority problems i updated to .77 and restored the unit, after that the sound priority worked perfect, but now there is another problem. When i installed spotify i had some offline playlist and now i haded more offline playlist but the problem is that when i turn off the car and then on, the playlist and configuration are allways back to that first configuration, so i thought, ok lets delete the spotify info, but the file is undeleteable (from the file browser and from the spotify app) even if i log in with other user if i close the spotify app and then open it again it will log in with the first user and again the first configuration as the configuration and user files are not deleted. So I rooted the device because i though may be with root acces and a root file explorer i could, but no, i also tryed with terminal and it says it cannot delete it because its a read only file, the permisions of the file is rwxrwxr-x and even trying to change the permisions is not posible. I also restored to default settings a couple of times, but the files still there. Dont know what else to do to delete the files, any tips?

I recently picked up a CaFi Dashlinq4 and i suspect it may be based off of this same hardware. Is there any way for me to confirm?

If it is, then the Dashlinq4 may be of specific interest because they have bluetooth OBD2 dongles working.

Bluethooth not working

Anyone here knows what would cause Bluetooth die in this unit? This is a brand new unit which I used it for a week only.

Just after the install I had it working, but I had issues with downloading apps and cause I was getting an error, I tried the factory restore. After that Bluetooth stopped working. It keeps searching but nothing is discoverable. It looks like it is turned off or it is not powered. Tried to push the latest firmware 2.6.70 (Mirror 2), but other than the update itself nothing changed as far as Bluetooth functionality.

And by the way, what mirror 1,2 or 3 means?

Any help on figuring out and fixing my Bluetooth would be greatly appreciated.
[Android Head-Units] jpapadami:
Try using Droid Hardware Info app or something similar on your unit and post back the hardware specs so we can compare.

2.6.96 is the latest. Try it and also update your MCU file.

SWC for 99 Infiniti Q45

It appears that my buttons don't get passed to the can bus, but are encoded to a single wire interface and then decoded back to 5 independent signals. I haven't hit this with a meter yet, but the factory service manual indicates this is a "pulse signal"

Will the AN-21U decode a pulse signal? I've read here that many people are using a PAC device or similar, but some experience discreet voltage levels, or resistance values that can inform the head unit when a particular switch is pressed. I've attached 3 excerpts from the fsm and put a purple asterisk (in 3 spots, same signal) at my point of interest. Can I connect that to the KEY1 line? If I do, should I ground the KEY2 line, or leave it floating? I may just go in there & take my chances, but I've read this entire thread & some of you fine folks seem quite knowledgeable in this area.

Ive had this unit for approx 2 months now and find that using the touch screen while driving is a bit awkward. I'm considering hooking up the 5 decoded lines to a teensy (as an HID device) and having it send keycodes that android understands at the system level.

Your help is greatly appreciated

Here you go:
[Android Head-Units] jpapadami:
Go to Shadowmike's repository and perform the following.

1. Download the 2.6.96 firmware and upgrade your unit.

2. Download the mcu96.zip file. Unzip it. Find 4.2.13-10-10-2501.zip (which seems to perfectly updated match your current MCU file) unzip it and update your mcu.

Kind of hard to view your pic upside down ;)

johnnybags, looks like pretty close hardware. do you have a bluetooth dongle? can you connect it and type lsmod in a terminal? or just check /system/lib/modules/ for the bluetooth.ko, btusb.ko modules.

I had the same problem, I have solved using root Explorer. All the permissions problems comes with . 70 version. Try to update to .96 following the instructions to get root again and then you will be able to delete those files. Now I'm on mobile and it is very late, I'll try to help you better as soon as possible.

those were with an "azio" bluetooth dongle connected. there are 2 USB ports on the back, apparently one has to be used for the wifi dongle, so i used the BT in the other. not sure if changing would make a difference.

Can you give me a link to that unit ? I think you have it to me before. I like the look, I might get that to replace the hole in my dash.

[Android Head-Units] jpapadami:
Here are my hardware specs which has the same as the AN21-U but with no DVD. By the looks of it the only difference is the iNAND memory is twice the size in the AN21-U units and the Dashlinq4 has a better screen display (1024 x 600).

Anyone think that the firmwares are compatible and are interchangeable between units? I was think that maybe if ROM Manager Premium is installed on these units that we can extract a copy of the ROM. Has anyone thought about installing CWM on these units?

Just a dumb question. Why bluetooth OBD2 dongles needed? So far, unit bluetooth works fine on my iPhone 5s. Incoming/Outgoing is fine. Only con is it doesn't show contact name, instead it just show number. However, the unit phonebook do show name and number. Unit bluetooth tether works fine too. I'm not sure what is OBD2 dongles does???

Ok i updated firmware to .96 and mcu to 4.2.13-7-10-6501 but i'm not sure where to change Vol knob from right to Left. Below is the screenshot from Extra Settings. I drew this since screenshot not that clear.
[Android Head-Units] jpapadami:
This is for the steering wheel control. Under Extra Settings there should be an option "switch key nob".
[Android Head-Units] johnnybags:
Bluetooth tethering from my iPhone 5s to my head unit won't work, I have to do it via wifi unfortunately. It doesn't appear my head unit has support for the DUN or lan access profile that would be required for tethering via bluetooth.

Bluetooth OBD2 dongles are needed for running Torque so that it can display engine statistics on the head unit (RPM, oil temp, coolant temp, you name it.) Those work fine with my current unit, although apparently don't work an the an-21 u's from what i've read thus far. It also may shed some more light on how we can go about connecting other bluetooth devices in the future.

[Android Head-Units] jpapadami:
I'm still wondering why so many people are still keen on OBDII bluetooth? Using a USB connection gives you better throughput and doesn't drain you battery when your car is off.
[Android Head-Units] johnnybags:
I'm not sure either, but I do see the desire for unlocking the rest of the bluetooth stack. If these units are in fact based on the same hardware, understanding how CaFi implemented obd2 bluetooth support could lead to support of other BT profiles. That is assuming that this is a software limitation as opposed to hardware. With full bluetooth access, these headunits could gain a lot of functionality, bluetooth tethering, high refresh rate GPS antennas, etc.
[Android Head-Units] cat2115:

[Android Head-Units] jpapadami:
I agree. I hope that it is a software limitation because the vibe that I've been getting from this forum is that it's a hardware one. Let's see if we can't get other people to help out in this cause.

---------- Post added at 04:21 PM ---------- Previous post was at 04:12 PM ----------

MCU comes from firmware after you install and root your device. I believe it's in "system/etc/mcu". I'm still trying to find the answer where the stock apps come from? I know they're located in "system/app" but when I update my unit it doesn't update the stock apps. They stay the same from the previous firmware.
[Android Head-Units] cat2115:
hmm, if this is the case then why when we/I update the firmware, the mcu does not get updated? Had to do additional MCU update.

I agree with you, none of my apps get updated from .70 to .96.. It just odd :confused:
[Android Head-Units] jpapadami:
This is the case. Not sure why, but you have to update your MCU manually.
[Android Head-Units] PsychoMcSatan:
My guess is that the update process has no way of knowing what specific hardware variations you have. When I update MCU via the "Model Choose" method, I often end up with a different MCU version where stuff is broken, so the logic used to choose is clearly not reliable enough.
[Android Head-Units] MFKinSINY:
stock apps

Does anybody have an answer for this? After an update, the system does "something" to all of the installed apps during the first boot (modifies, enhances, streamlines.... I forget the exact wording) but nothing apparently changes. I've tried to update some apps (specifically the radio app) and I see no changes. Im rooted & have superuser installed (and use an app to check root access, as well as "root access granted" pop ups when Im in certain directories) I'm sure I'm missing something simple. I'm about to go out to the car & upgrade to 2.7.4 (thanks for posting it ionutlup) and comb thru the filesystem. If I can figure it out, I will gladly post my findings, I'm just hoping someone beats me to it hahaha.
[Android Head-Units] spazfishy:
Couple questions possibly some good stuff to add to the FAQ.

Hey, I have done a lot of reading but a few things remain unclear to me about this radio. I am hoping some others can help me.

1. Recent apps, is there anyway to open recent apps on this radio or see what is open in the background?

2. Voice search on keyboard, I see the option in settings to enable mic in keyboard yet I see no mic button to push when in keyboard. It would be handy to search with voice while driving. Anyone else have this problem or know how to fix?

3. Android uses dragging from the top down to get to notifications. This can be tough on my radio because of plastic at the top. Is there another way to access this?

4. What is a good launcher to use with this radio? I have tried a few but they seem to put the dock on the side vs the bottom. I could not find a setting to change this and I was wondering if anyone else noticed it.

If you can answer any of the 4 please do. Love this radio!

Thanks

[Android Head-Units] jpapadami:
Well I went straight from .70 to .96 and none of the stock apps changed. So how can going through each update be any different? Unless only certain updates change the stockapps, like .93 where your archived stockapps seem to come from.
[Android Head-Units] shadowmike:
It all depends on the update.

Install .96 you'll get different apps. I think .77 has different apps as well. I noticed the ui also changes slightly to be cleaned up whey update

The system apps obviously get updated otherwise you wouldn't have the new notification quick toggle. And new system menu settings

It's not odd at all.

When a custom Rom comes out for an HTC device we don't update firmware to run the Rom.

I have a HTC one m8 Rom on my m7 and I still have m7 stock firmware and all features work from m8 Rom.

Firmware is for the hardware..

A software upgrade is only for the Rom and system.

Where are all the updates coming from? Can whoever is getting them ask the supplier to implement the bluetooth.ko and btusb.ko
[Android Head-Units] jblade1000:
Not sure if this was answered already (my apologies if it has), but does your app only remount the external microsd card or does it account for usb mounted storage as well? I have a usb hub and two of the ports have 128 gb thumb drives in them, one for music and the other for pics and video. On the video and pic side, MX Player finds all the media its supposed to without issue, QuickPic finds all pictures without issue but i haven't found a wallpaper changer (in the Play store) that is able to find media in the directories on the thumb drive. on the music side of the fence, the only music app that reliably, repeatedly is able to find (and keep) the music location is Rocket Player (yes even PowerAmp didn't work as expected for me). Problem is I like (and paid for) Mixzing and would much rather use it instead but ofcourse it can see the default mount locations this head unit uses.

Since we use your app at our own risk, I figured I'd ask before experimenting. Thanks!

I was thinking the same thing, so after some Googling and Google translating, it appears that folks on the Russian site 4pda.ru received it from someone named Allison. I suspect she's probably the same Allison ( allison@szcreat.com ) referred to a few times in this forum as a rep from Tonghai Create.

I'm still at work, but looking forward to seeing if the new version has anything new, specifically a compatible MCU. It sounds like they're the same version as the ones in .96, but the one I need was missing. Can anyone who has installed already check if there's a 4.2.13-7-10-2501?

I went through the entire 88 pages of the thread at 4pda. There were a few posts about possibly changing the bluetooth sub-board on the main board but no progress so far. It seems that there are 2 versions of the bluetooth sub-board. The people with bluetooth obdII working show no btusb.ko or bluetooth.ko which must mean it is controlled entirely by the bluetooth sub-board.

Also the guy that keeps getting the new firmwares from allison has requested the btusb.ko and bluetooth.ko be added but nothing yet. I did not see any contact info for allison anywhere.

One thing of interest though, one of the guys there replaced the 4x45w internal amplifier with a 4x50w amplifier pn: TDA7850

This information regarding the Bluetooth boards is not new, we already talked about it very shortly after I purchased the unit.
