During my misadventure with upgrading this last time I was trying to figure out more about how this thing works and came across a few tricks. Google tells me some Jeep and Charger and 300 owners have figured out some of this too, but for the benefit of Ram owners I figured I'd make a new thread to collect all this stuff in one place. If you press and hold both the temperature-up (red arrow) and temperature-down (blue arrow) buttons at the same time, for 5 or so seconds, you are presented with the 'Engineering Menu' like so: All kinds of interesting things in the submenus, like you can read out the specific versions for each module: Another trick is to hold the up, down, and front defrost buttons simultaneously for about 5 seconds and then you are presented with the 'Dealer Mode' menu: I know what you 8. Mud Puddle Visuals Showing on this page. 4A owners are thinking and NO, you can't just press the navigation activation button and save $600. It requires you to input an activation code, which is what the dealer gets from Ram when you pay them all that money. Another trick is to hold down the up, down, and Browse/Enter buttons simultaneously for about 5 seconds.
Uconnect Ra3 Hack. The time now is 1. And was told that a uconnect case manager would call me. I've received no calls from them. Cost to Activate the Nav on UConnect 8.4A?

That puts you into touchscreen calibration mode, where you just follow the on screen instructions: The last trick I know about so far is to hold down the up, down, and rear defrost buttons simultaneously for about 5 seconds. That will write a screenshot (1.2MB.bmp file) to the flash drive in the console USB slot. Which is how I got all the pictures for this post! It will literally capture whatever is on your screen, including the backup camera image and radio info: One thing to remember before you insert your flash drive to capture screens: don't use one that still has the 'swdl.iso' file on it from your last upgrade! Samson Sound Deck Protect. The most annoying thing I noticed during all this: the screenshot files have the precisely correct time and date (in GMT) on them.
Despite the fact that this radio can't keep time worth a darn and randomly loses a couple of minutes every day or two. So the radio is getting the correct time and updating itself, but they still use some broken algorithm to run the displayed clock. That's it.any thought from anyone about it? I wonder if its an inline module like a lockpick, or if its being ran from a USB or sd card, or just mimicking a phone/tablet interface.It looks like they're just intercepting the video and touchscreen signals and routing them to some external box (phone?
Tablet?) running Android. It's switching back and forth way too fast to be something that's booting and running on the 8.4 hardware itself.
Heck, they have to route any audio back in through the AUX port! I welcome this thread turning into a place where we figure out how to make the Nav address entry work at speed (by the passenger of course!) and so on. I have figured out a few things about the system at that level but not enough to be generally useful yet. Just enough to bypass flaky aircard hardware during the update process.
Things I'd like to know, if anyone already does, or will keep working on myself: -- How to produce an ISO file that the system likes enough to execute from. (So far I've just had to patch an existing one; not sure how they're spotting the legit ones vs ones I make.) -- What USB-ethernet hardware it recognizes (I'm assuming it must, to allow access to the system via telnet, SSH, and/or a web interface during development) and what its IP address is once hooked up that way. I can tell you that the hardware is running the Qnix O/S and the update procedure runs LUA scripts with some Flash thrown in for the screen output.

I wonder if whatever they're using would work on US trucks.
