my apologies for straying off topic and being (way) late to the discussion but...

just bought a car with this hu, however, the previous owner provided no access to any of the usb ports (only did an ipod connector to center console).

anyway, is there a way to update the firmware short of using usb? i've tried writing to disc, sd card...don't see a way to bt or wifi transfer.

thx.

Only USB

I'm back up and running. My new cable works great. I spoke with my friend. Bricked units are sent back to Kenwood and a replacement unit is sent back. He has never gotten the same unit back. He did try to email Kenwood in Japan and played it off like he had a customer in Angola with a bricked unit and wanted to see if their any other recovery possibilities. Let's see what comes of this.
[Android Head-Units] chris.davis925:
does your friend do any reflashing of the unit? What about when the unit is slow or had another kind of error message do they do a reflash at that point?

I'm also curious to see if you can get any kind of serial communication out of the other two ports?
[Android Head-Units] aplusmiami:
I have my test unit up what do you want me to check on the factory wired USB ports. How can I turn them into host ports let's say to hook them into a pc?
[Android Head-Units] chris.davis925:
I am referring to the other beige connectors. I think your board only has one other beige connector. It doesn't have a side beige connector, right?

Either way, can you test to see if you can get any kind of serial communication from the beige connector?

Also, do you have a test unit to play with that is not your every day radio? If I compile a clock work recovery image, would you test it?
[Android Head-Units] aplusmiami:
I only have the one beige connector on the CPU board. The other one apparently is on the audio circuit board

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

Mine does not have that. I sold my spare radio. I can see if my friend has a new one I can play with.
[Android Head-Units] chris.davis925:
Okay. Let me know.
[Android Head-Units] aplusmiami:
He wanted to know how confident you are that this will not brick the unit.
[Android Head-Units] chris.davis925:
Well... in theory, it's just replacing the recovery image. So, worse case scenario the recovery image gets screwed up and you have to power off the unit. The next boot should be the normal boot image at which point you can replace the recovery back to the default one.
[Android Head-Units] aplusmiami:
. Coming from a store with the unit in hand I hope we don't break it

I got my deck back from the kenwood service center.

Good news: it works.

Bad news: I can't get USB interface to register anything.

I've hooked it up as per our previous discussions and even during Stand By / and during an update I get "Device Unknown". I've also tried flipping the USB data +/-.

Aplusmiami, you mentioned previously on this thread that you were using the beige connector NOT on the android board. Can you elaborate?
[Android Head-Units] aplusmiami:
I am using the connector on the CPU board.. they're is nothing plugged into it.
[Android Head-Units] chris.davis925:
Want to trade one of your many units for mine? lol

I can't get it to interface USB anymore. Even though the unit works just fine.
[Android Head-Units] chris.davis925:
Whoever has a dnn990 (regardless of root) can you please post your version information here?

Please do it this way:

-Launch the "search" app

-type: version information

-push the back button. You should now see the version app listed under the "applications" section of the search results.

-open the Version Information app and take a picture. Post the information /picture here.

I am interested in this information in order to figure out the different versions of the dnn990hd out there.

Thanks!

[Android Head-Units] chris.davis925:
Thanks. Are you on update 1.03?
[Android Head-Units] funkytrone:
It connects to my wifi at home and at work and I haven't seen any update notifications. I guess it's on whatever update is the latest. I also sent it in for repair back in January. They may have updated something else on it.
[Android Head-Units] chris.davis925:

Keyboard

I connected a keyboard to my DNN990HD tonight and several commands work which makes me wonder if there is something to your statement.

I was able to restart the device and scroll through menus but could not figure out a key combination to enter recovery.
[Android Head-Units] aplusmiami:
Sorry been busy with side work.. Need that extra $.. What port did you plugin to get the keyboard working?
[Android Head-Units] c4manceph:
I used the same USB that is used for updates
[Android Head-Units] chris.davis925:
Hey, can you try to get the version information on your DNN's as indicated in my previous post? I am curious to see your version info on the decks that are presenting USB on the beige port.
[Android Head-Units] c4manceph:
I set out to do that for you yesterday evening but for whatever reason I'm not able to figure this out. Not sure what I am doing wrong.
[Android Head-Units] aplusmiami:
I tried:

-Launch the "search" app

-type: version information

-push the back button. You should now see the version app listed under the "applications" section of the search results.

-open the Version Information app and take a picture. Post the information /picture here.

The unit tries to go to google to a search.. I pressed the back button and it just gives me the keyboard and text entry screen again.

---------- Post added at 03:12 PM ---------- Previous post was at 02:12 PM ----------

Can you post information on adding option for:

install from unknown sources

in the setup menu.
[Android Head-Units] chris.davis925:
Once it does the Google search click back (like you did) you should see the keyboard. Now, hit back again, it shouldn't exit the app, but will show you a local search of the text you entered.
[Android Head-Units] aplusmiami:
Actually had to press the Spy Glass and select Apps.

I get the title bar version information

But nothing else.

oh crap - I was going to try and push android system information.apk to the unit but now all I get is the kw splash screen and then it goes black...
[Android Head-Units] aplusmiami:
Unplugged from my PC and the update continued

Im ok
[Android Head-Units] aplusmiami:
How did you get the unknown sources option???????
[Android Head-Units] aplusmiami:
I am havng an issue - At what point can I install an APK?

I was able to install ES Explorer and terminal but know I can not install anything else?
[Android Head-Units] chris.davis925:
That's because your root wasn't permanent and your ADB's ability to talk to the android terminal/shell has stopped.

I get my second DNN on Tue and I will let you know if the permanent root script works. If it does, I will post it. If you are willing to try it without waiting PM/ Skype me and I will send it to you.
[Android Head-Units] oxman504:
For some reason I haven't been getting notifications for this thread untill this morning. So I just wanted say great job so far and keep up the good work. If I got this right yall are having to open up the unit and plug in a custom cable to one of the boards in the unit correct?
[Android Head-Units] chris.davis925:
That's right.
[Android Head-Units] oxman504:
That sux. I was hoping that it could be done through the update usb, because to take out my unit is a PITA. I'm no rookie when it comes to car stereo installs, it's just the nature of this install. Can the custom cable be installed and left in without any mods to the unit? Is it possible that later on we will beable to update through the existing update usb or aka ipod cable. This stuff is way over my head as far as the coding goes so a dummy way to root would be necessary. Where there's a will there's a way. My truck is in the paint booth, but when I get it back together I will post my unit info if still needed.

HI all I am at a standstill. I have a DNN990HD that doesn't appear to present itself on the USB port. I am unsure if it's the unit or possibly my laptop. I have two laptops, one of them I know for sure there are problems with USB. The second I am beginning to be skeptical of.

I know this is a stretch - but I am wondering if anyone would be willing to trade one of their DNN990HDs with mine? I have a new perfectly working one.

If not, unfortunately I will not be able to move forward with any work in regards to root, unknown sources or speeding up the unit.
[Android Head-Units] chris.davis925:

[Android Head-Units] BushmanLA:
Hey gents.

I've got one of these units sitting around doing nothing. I'm not an android or linux nerd, but I'm an EE and I have access to a nice lab and a team of little old ladies who can solder anything.

If I can help out in any way please let me know.

I refuse to install this steaming pile of junk in my truck until I can root it and make it work like it should. Keep up the good work.
[Android Head-Units] golgothagecko:
So do the custom apps play through the Kenwood DSP system? I wouldn't want to lose audio quality if I change to a different ipod app.
[Android Head-Units] chris.davis925:
Yes, they are still processed by Kenwood's normal processes.
[Android Head-Units] golgothagecko:
Amazing! Can't wait to replace the crappy ipod app with something more functional!!!

DNN990HD root

I have bought DNN990HD and would like to root it. I have gone through whole history from 2010 to 2014. Extremely impressive, the last post below mentions that finally it has paid off and you have a solution. When are you going to share it, also I will be happy to donate $40 for it.:good:

I have the HTC one m8 verizon. We got temp root through Weaksauce. It enables root access at boot and we were able to run Superuser. As soon as we rebooted the system was unrooted and Weaksauce would run at boot to enable root. Sounds like we need something similar
[Android Head-Units] swyner:
Any update on this? I saw the youtube videos and super excited to see this!!!!!!!!!! If we can have this unit boot faster, have Android rooted and all the apps (tunein, etc) play through the Kenwood audio processors....this will be awesome!
[Android Head-Units] aplusmiami:
I think we are at a point that it may not be worth it. Get a 7" tablet with a Verizon card and hardwire it into the vehicle.
[Android Head-Units] siralsmooth:
Here's the issues with that. With a tablet, custom mounting will be needed. If you leave the charger plugged in but off, battery drains overnight, at least with my nexus 7. Then the issue of USB DAC or 1/8in for audio, where as the Kenwood has 3 5v pre amp outs with lots of control and adjustment.

Or the other scenario that I've been working on for my own car, a 7in universal touchscreen with multiple input, cga converter for factory rgbs signal, HDMI for android, av1/2 for front/rear cameras. Biggest issue so far is either hack a few components to make a custom cable for simultaneous otg and MHL so my note3 can do video and have a touch input. Or the other option, use a mini PC. Problem with the mini PC is you have to properly shut it down everytime, as well as wait for it to boot.

Personally, getting root isn't the biggest problem, especially if we can sideload apps and run an alternative launcher already. Would be nice, but not necessary.

Does anything stay on reboot like sideloaded apps or are they gone as well?

Hey Chris.. been busy with work however just got laid off.. so now I have time. What do you need? Testers that are willing to brick their units? I can get a used unit to play with.. also can post on the Kenwood forums. Lots of unhappy dnn990 HD owners willing to cough up $$ if there is any chance of salvaging the UI
[Android Head-Units] LostinCanada:
I wish someone would find an answer to this! For fun I emailed Kenwood technical support and asked them directly, and received the expected answer that the information is proprietary and unfortunately they couldn't tell me. :( LOL I guess that would have been too easy.

It would be great to be able to add/remove apps from Google Play store, as well as install the Android swype keyboard!

Is anyone working on this unit?
[Android Head-Units] dbmdude:
OMG me too...

I recently bought (and had installed by Car Toys) a brand new DNN990HD. When I first got in the car they showed me how to pair my phone and it paired properly. I had to do a full reset on the device because the Car Toys people could not tell me (and I could not figure out) how to get back to create the owner account. Anyway, once I had to reset it again, the phone stopped working. It pairs but only the Media connection works... the phone is useless and I cannot figure out why. Now every time I pair it... it will only pair media.. and Pandora for sure DOES NOT WORK.

I have many gripes about my new purchase but this one really frosts me to the core. Another one is WHY do you have to pay for voice control? The basic commands in the HU are there but in order to use Voice Control for other software items you need to get a pay Nuance account... that's garbage.... also I cannot get the "My Location" to do ANYTHING... I try to add a City and it just sits there fat dumb and stupid... I type the city in and click Search and get nothing... I even tried Seattle (I do not live there) and it cannot find Seattle.... are you completely serious?

Plus since the device requires WiFi for anything cool and my Galaxy S4 hotspot does not auto connect (auto turn on) I have to remember to turn it on before I drive away....

ALSO... the USB connection upgrade process failed miserably... the device never recognized I had a USB flash chip hooked up... so I cannot upgrade the firmware.... and I even tried SD even though the instructions say it is USB only...and that failed even though at least it saw the SD chip.

:mad:

GEE...... so much fun!!!!!!!!!

Is there any setting anyone can think of on the DNN990HD or the ATT Galaxy S4 that would enable the phone????

Thanks!
[Android Head-Units] IGO2UA:
The head unit is quite slow. When you upgrade the software use cable marked iPod and follow the direction from Kenwood's site. I have the Verizon Galaxy S4 and I usually have to reboot my phone before Pandora will work and I usually travel 3 blocks before the connection is made. I have not experienced any issues with the GPS.

Hope this helps.
[Android Head-Units] ScottyMCSE:
I just installed Pandora on my new DNA last night. I will check it out today on the head unit and report back. Everything else works as advertised on my 990. Maybe dbmdude got a bad one? I'll let you know how Pandora does.

[Android Head-Units] jazzsax3:
The Pandora issue i remember having. I think what I ended doing to make it work was remove the phone from the headunit. For some reason though I think you have to be connected to remove it because it won't let you go into the settings of a disconnected phone. It's been a couple weeks and I tinkered with other things at the time so i don't remember clearly. Also check the Phone setting while connected on the Headunit and make sure Pandora is enabled.

As for the Remembering to Tether. Look for "Autotether for Automatica" on the Play store. It turns on tethering when the Bluetooth Connection you specify connects.
[Android Head-Units] LostinCanada:
I bought my unit from Crutchfield out of the US and with their excellent technical support and included wiring harness/dash kit I was able to install the unit myself... much better to do this yourself IMHO - saves $$$ and you can ensure everything is hooked up and working to your satisfaction. Plus I'm kind of a control freak when it comes to my truck - LOL I won't even let anyone put gas in it... (It's not even a new/fancy truck either) :)

I too had some issues pairing, and with the firmware update, but that was solved by calling Kenwood tech support and having them handhold me through the update process with them on the phone. Worked perfectly. Re BT, I had to make several attempts, but I think the magic solution was to answer yes on both the phone and the head during the pairing process. Once paired it will auto-pair no problem.

I did notice that sometimes the media portion of the BT pairing disconnects itself so if you're having trouble streaming audio then check the setting on the phone to ensure both phone and media are checked off.

Re Pandora, I'm in Canada so I had to do some workarounds to get the Pandora app and am using the Hola app to enable the Pandora service while in Canada on a Bell SIM card. I will be interested to try a US SIM card on my next road trip south to see if the Pandora app pairs seamlessly when workarounds aren't involved.

So far I'm able to listen to Pandora via BT streaming on the DNN990 but at the moment I can't get the Pandora controls on the head to work - so I'm controlling Pandora from my phone until I find the problem.

I plan to call Kenwood technical support to troubleshoot that issue and I will report back as to my results.

Overall I am extremely pleased with the unit - it's the only one of it's kind on the market so I wouldn't expect perfection. It won't take long for the major players to start competing with each other to provide more features. In its present state as a new technology (for the car audio world) I find it awesome enough that I don't regret the purchase. Of course it would be even more awesome if someone could help root the darn thing! ;)

I'm on a Samsung Galaxy Note II (Bell Canada network).. Android 4.1.2
[Android Head-Units] LostinCanada:
Further to my earlier post, I tried a few troubleshooting steps on my own this afternoon, and have come to the conclusion that I am getting Pandora on the Kenwood solely by bluetooth audio streaming from my paired phone (connected to phone/media). I tried to unpair the media part, and connect to Pandora using the Bluetooth (as opposed to wired) option. I keep getting a message to "Check Device". I now think think the problem is with pairing issues with the Pandora app on the Kenwood.

I guess I'll enlist Kenwood technical support to help now that I understand more clearly what the problem is.
[Android Head-Units] dbmdude:
UPDATE to my original post...

This turned out to be a HU defect... replaced the unit and after two upgrades (device firmware and Bluetooth firmware) this works now. The original problem was that it would not pair properly but after the two upgrades on the defect device it paired 'sometimes' and when it did the pairing would not be retained after reboot.

I still have the above gripes... I have installed the auto tether utility and have yet to try it out (going to today)... but I also discovered other things that are really annoying... please go search for my posts (dbmdude) on kenwoodforums<dot>com.

Thanks!
[Android Head-Units] Antd0g:
I just tried the auto tether utility and it works GREAT. Now I don't have to manually turn on tethering every time I start my truck. Now if somebody could just figure out how to root the DNN series head units I'd be good.
[Android Head-Units] LostinCanada:
Ok... update re Pandora... kept on with my troubleshooting and discovered the problem. Basically Pandora competes with your phone for bluetooth connection, so to get it to work, you pair the phone for telephone and de-select media. Then, in the settings for the paired phone (in the Kenwood), ensure that Pandora is selected on. Then the DNN990 will control the app on the phone.

After trying this out though, I have decided that like the limited Facebook and Twitter apps installed on the unit, the Pandora app is similarly limited and not as good as the phone app. So I will likely disable the Pandora app and use the media pairing (bluetooth) to stream Pandora through the unit and control with my phone.

Glad to have figured it out. So my feedback to Kenwood is going to be, great stereo, awesome capabilities, but they really need to work on their apps and Android functionality. Since most of us travel with our phones, we expect more functionality from anything with an Android OS! Why these apps are all dumbed down is ridiculous - since the screen on the Kenwood is bigger than that on my phone, I'd much prefer to use the fully featured apps on the Kenwood screen than that of my Galaxy Note II.

Hope this helps someone...
[Android Head-Units] swyner:
All, I noticed that you cannot get the telephone portion of bluetooth working UNLESS you select "No" to use OEM Bluetooth when setting up the device. This is what happened to you dbmdude. I have reset my unit a bunch of times and found this out the hard way!!! I believe you can go into settings, system then OEM or somthing to ensure that is set to off.

Anyone have backup camera working properly? Anyone with more news on Andorid development (hack) for this?
