Carperformance.se Uconnect Android system help.

i am looking to get this also. I am very curious how you like the device - it looks great though a bit out of date. Waze & email should work well. How much storage does it have? Can you add a sd card or something?

How did you get it installed? Who?

got any pics?

Actually I would be interested in this too, I have an Alfa Romeo and the Uconnect 6.5 (european version) which isn't that great, it would be nice to attach a sort of box with ARM hardware running on Android and using the display and touch of the existing Uconnect. The question is, how this can be done?

http://www.dodgedurango.net/forums/.../24632-android-phone-uconnect-8-4-screen.html

I would check out this thread. It has two videos that walk you through the entire process - great info!

I also bought this latest Android system V4 2 weeks ago. Auto launcher pro app is very good working. At the moment there is a issue with the system time, which is not correctly synchronized with gps time. Carperformance Team is working on a fix for that. How can I get root Access for this Android 7 System?

glad to hear i'm not going crazy with the clock but there is an issue.

I just bought and installed a V4 a couple weeks back too.

i must have left a loose connection cause i keep having to recall the touchscreen for android. I half-arsed the install cause we were leaving for a 2k mile roadtrip the next day- need to take it apart and do it right. Luckily you can connect a usb mouse in to trigger the calibration app.

id also love root- at the moment im trying to figure out if the one usb port is safe to connect an A to A usb cable into to get ADB. apparently on some versions of nvida sheild, you can. If they provide a firmware update for the clock fix then maybe that gets us an image to futz with for root.

a keyboard also works in teh usb port and i've tried a handful of key combos during boot to get to recovery but haven't stumbled on it yet.

I'll post back if i find anything

Hi @michaelk

Good to hear that I am not alone here with this special system V4. Except for the issue with the system time and no root access, I am fully satisfied so far. I hope to fix it soon. If we had root access then we could solve this issue with the system time with some time apps ourselves.
Thank you for your experiences.

Best regards

wiring harness investigation

so played around some today.

I've got an issue where I need to recalibrate the screen almost every time I boot. it seems the box (or card added to the radio?) forgets things and only works the bottom right corner and also seems to rotate 90 degrees at boot. The end result is unusable screen. I think carperformance is just a reseller because of their response. They're friendly and reply quickly but are really unable to help. The first answer was just randomly fiddle with screen and try to find calibrate setting and reboot- that proved impossible and on my own I discovered a 6 dollar USB mouse from the Walmart could be used to navigate to the calibrate app. When I inquired again when it got more frequent they basically said it's not normal and offered no help except to adjust a personalization setting to run calibrate on boot- that only works once that I can figure (might be related to weird time bug)- so I settled on having tasker run calibrate on each boot. I wonder if there is a battery in the box that needs changing but the warranty sticker keeps me out for not- might add an external battery to keep it alive for a longer time to minimize the rebooting

Anyway took everything apart today to double-check and can't find any connection issues. I traced the harness a bit to try and understand a little and basically, the skinny cables run the daughterboard to snag the screen output and the touchscreen input. But i wanted to figure out what is tapped from the radio harness to the large white plug on the box and see if anything going on their .

DISCLAIMER- I NEED TO CONFIRM (it was hot - laughing) but basically seems what is tapped in radio harness is:
1) power and ground also
2) L&R aux audio signal- interesting here is they tapped a single ground (physically next to the right signal) for common. Earlier i had the RAX hack and their harness used a ground for each L&R and their aux input worked all the time without the little plugin shunt thing to trick aux input. When i dug some more and found a pin diagram from mopar I found that the 'left' ground is actually labeled "aux audio device detect signal" I need to play some more to see what happens but my guess is if we put a switch on that to short it to ground then the aux would just work to avoid the hokey plug.
3) Here's the fun- holding the screen to flip inputs could be the daughterboard running things. BUT since it also reacts to the left steering wheel button pack and switches inputs itself when you need the reverse cam- i figured it reads the can bus. and sure enough, it looks like it taps CAN IHS (+) and CAN IHS (-). Very cool that it would get into the whole bus and read anything- BUT since there are other FCA vehicles that don't auto-switch inputs on revers and they have alternate connections it seems the real dev is not involved to update things to sniff for other reverse signals. Reading around here- seems that there is probably a custom serial port someplace in the box that reads this and there's probably no documentation for us to do anything ourselves. But one can hope...

So the spec for the chipset for the V4 says it can handle an OTG port and a couple (maybe 3?) other USB ports. Obviously, the box only has the one USB A port visible on the pigtail. I wish we could get in the box and look for a header for the OTG port to help rooting but.... the darn warranty sticker.

on the FCA/Dodge side of things- I have a Durango with a USB port and SD card reader in the dash (USB Media "Hub" Apparently, FCA uses USB Mini B connectors to interconnect all the ports and the radio. They use latching connectors that are keyed but if you undo them there's a standard USB mini B in there. They do some odd male/female things so you have to pay attention to where you undo cables, but bottom line you can undo the connector on the back of the dash's USB port and stuff a USB mini B female on it and connect it to whatever host device you want.

I first tried an old laptop in case there's anything weird going on. My Dash "Hub" actually has 2 mini-B connectors and a multipin auto harness. Without the harness when you connect it to windows it sees a USB Hub, but the USB port was still dead. So I assumed it needs power from the harness on the back of the dash hub and connected that. UP popped up a USB mass storage device which I believe is the SD card reader- didn't get around to confirming and then the USB port also comes to life. Knowing that it was safe at that point I connected it to the USB A Host port on the box and presto chango now I have the in-dash port connected to the android tv box without any exposed wiring.

Connected the "android auto dongle" through the cars USB port and that works perfectly. I ordered a used 2 USB dash hub from eBay (later model years have 2 and will see what that does. The pictures of that also show the 2 mini B ports- I'll play some more when I get that. I'm not sure what is in those dongles but from the other folks hacking android auto into older models (by using newer radios) apparently, one port works for android auto and the other doesn't. The scuttle is its a body module programming thing but I wonder if maybe there's something physical in there and so the dongle won't be necessary any longer with the new hub? My other thought is if the two USB min B jacks allow you to connect to 2 different hosts- I would try one on the original Uconnect (in case I ever need to update the software) and the other for the android TV box.

So apparently the android tv box handles hubs just fine. As I mentioned earlier it handles a mouse or USB keyboard fine. Also, I played around and connected my hotspot by USB instead of wifi so the device sees it as a modem and that works just fine- so I assume a USB modem works out of the box too. (again odd if that works that carperformance sells a hotspot and not USB modem- like they don't know what the box can do)

I disassembled my display 2 times until it worked. After the first start, I had a black screen. I thought that was it... After 3 times it finally worked. I also had a cable on the plug which has easily resolved. I think you will also have a loose contact somewhere. One time I also had the display calibration gone. Then I connected my old usb keyboard and could then start the display calibration. I reset the system before. So far, the system works without problems. I also have a passive 4-way usb hub to connect.
I have already connected cables for the frontcam but have not yet moved into the engine compartment.
In the video tutorial of Carperformance, you can see when you switch to drive, the display then changes to the frontcam or signal from the cam, but the display does not change to the Frontcam signal with me.
Do you have with you the signal on the display of the camera when switching to drive?

Adw2 = bad mix

Went back and forth many times in email and turns out my calibration issue was probably all ADW2 launcher, guess it conflicts with whatever app they use to communicate with the display.

in the process of troubleshooting I got the update zip for the current version but I don't think those have recovery partition in there and so can't help root? I need to read some more.

I've ripped everything apart like 12 times with the screen, so that my front cam is not connected right now. For the brief time I had it, it was connected to one of the smaller video in pin connectors and don't think it worked in drive by itself, but can't really say for certain. I think certain models can't get the canbus command to see reverse and if I understand they connect in to the video in on the main connector and then use a point on the car that is energized to trigger the switch on that connection. If your adventurous they seem to have to flip a dip also. I think it's the Cherokees or maybe grand Cherokee so maybe Google their thread's? This site gives connector pin outs
http://connectors.dcctools.com/home.htm
There might be a lead for the drive on your shifter if lucky. I think I read the reverse shoulder comes from a body control box in the passenger wheel well?


Also they're super friendly and never wrong when you email but they can be brief. So you could ask if there's a dipswitch to flip to enable auto switching one of the inputs. Hec maybe we should just ask for a table of where the dips do...

(Sorry for any typos... Will try to edit later)

Supposedly it is enough to connect the extra input cable for DVD or CMMB. That answered me Carperformance. Before, I had no external input cable connected. That's why no signal came. The OEM rearcam works flawlessly.

Also, I forgot, they have a workaround for the clock bug

For the clock there is a fix

It's a cheaper fix but so no solution. Carperformance should offer a software update with root access. Then we would be satisfied. We should expect it for the money.
My frontcam is working now good.

You already tried Android auto? Which USB dongle do you use? Do you need a special app for this?
My China usb dongle does not want to connect properly with my oneplus 6T.

Edit:
Android auto is working with Pumpkin USB dongle and autoplaybox app. The noname China scrap goes back to shop.
The time fix is working until now also. Thanks for this info. The carperformance, they wrote or informed the affected people who ordered it. I did not get any info.

besides powering your camera and connecting the yellow RCA video signal did you have to do anything else?

something with the red signal wire maybe?

I cant consistently get a signal on my front cam and not sure if the camera is bad or my setup

few other notes for others-

FCA "aux audio device detect signal" harness line is actually normally closed (I think shorted to ground)- if you break the connection the oew radio flips right to aux in. make the connection again and it flips back to previous input.

the in dash usb port is infact a powered hub. I originally had a usb + SD card combo and replaced it with 2 usb port and works fine. FCA uses mini b connections to it- just use a usb a to mini b cable to connect it to the android auto box and your indash usb port(s) will work on android auto (And provide more watts to charge your stuff). oddly either dahs hub has a second usb mini b connector that i played around with a little but never could figure out what it does

more can bus fun! - i updated the dongle firmware on the android auto dongle sold direct from carperforance and now it has a beta feature to map buttons. somehow it seems to be sniffing the canbus through the android tv box. it has arrow keys, numbers, enter, etc and you use the app to select the input to assign then you press the same button on the car twice- it sniffs the signal and assignes it. I My durango has the button packs on the steering wheel and i was able to assign up, down, left, right and get it to have the android auto respond. Need to play more but i think it actually goes android wide. For example i think the down button on my steering wheel was sending page down to the chrome browser i had open on the box. Pretty cool stuff if they expand that.
