How To: Install a 2018 4C (UAQ/UAS) Radio in 2013 - 2017 RAM
Unfortunately, you do need access to both CAN lines. The reverse switch signal comes in over CAN-C but the messages to display the backup camera are spit out over CAN-IHS.- Errol Smith

The 12V socket is down there and that's keyed. Shouldn't be too hard to tap into that.- Errol Smith

How To: Install a 2018 4C (UAQ/UAS) Radio in 2013 - 2017 RAM
So thanks to @Roman217 and @ManualCummins issue #2 is resolved! Powering off of an accessory run circuit rather than a full-time hot circuit fixed this. Since there's no key switched power behind the radio that might be out so the BCM might be the next best thing. I'll fiddle with it some more.- Errol Smith

How To: Install a 2018 4C (UAQ/UAS) Radio in 2013 - 2017 RAM
Right now it's powered off the USB port but could run from either a switched source or hot all the time. The microcontroller draws 100mA at full speed but is sitting basically idle when the truck is off. I'll measure current draw, though, and make sure. I know there are ways to put the thing to...- Errol Smith

How To: Install a 2018 4C (UAQ/UAS) Radio in 2013 - 2017 RAM
That wouldn't be too hard to add, actually. What's weird is my backup lines disappear after the 10 second delay but when I swap in a 2018 camera the lines stay all the time. This function seems to be part of the camera and not the radio.- Errol Smith

How To: Install a 2018 4C (UAQ/UAS) Radio in 2013 - 2017 RAM
Thanks for that, bud. Believe it or not, I'm a mechanical engineer so this isn't exactly my strong suit but I've spent my career in robotics and love a challenge. It's been a good opportunity to learn about CAN-BUS stuff and helps anyone with a G56 who might want to do this conversion in the future.- Errol Smith

How To: Install a 2018 4C (UAQ/UAS) Radio in 2013 - 2017 RAM
The reverse signal on the CAN-C line seems very repeatable. The main benefit of a hard trigger, though, would be only needing one CAN transceiver instead of two. Of course, using CAN-C you can put this little module anywhere you have access to the CAN line like behind the radio. If we use a hard...- Errol Smith

How To: Install a 2018 4C (UAQ/UAS) Radio in 2013 - 2017 RAM
That'd be great! I'll message you! Having it in the OBD port is convenient for developing this, but I won't want it there long term. I've already got a CSP4 switch attached to it and I brush that every now and then when pushing in the clutch. Back of the radio should be much cleaner.- Errol Smith

How To: Install a 2018 4C (UAQ/UAS) Radio in 2013 - 2017 RAM
I've got issue #1 sorted. I had a typo in the code that was causing it. Fixed it and now you can manually turn off the backup camera, shift out of reverse, then go right back into reverse and it works. Issue #2 is still there but less severe. Shifting out of reverse then back in makes the...- Errol Smith

How To: Install a 2018 4C (UAQ/UAS) Radio in 2013 - 2017 RAM
Thanks bud, I've got a premium cluster already but what's this with the song title and TPMS stuff? My TPMS works perfectly with my cluster but certain satellite radio stations don't show up...is that because of the year of the cluster? I got the thing off eBay and am not sure what year it's from.- Errol Smith

How To: Install a 2018 4C (UAQ/UAS) Radio in 2013 - 2017 RAM
If you want to send me the T-harness, I'll build one of these around it for you. Right now I'm tapping into the OBD port but in line to the radio would be pretty sweet. I've found 2 problems with it so far: 1) If you shift to reverse then use the soft key (the X) to turn the display off then...- Errol Smith

How To: Install a 2018 4C (UAQ/UAS) Radio in 2013 - 2017 RAM
It works! It's a very messy setup right now but I'm just going to tape it all up and zip tie it under the knee panel for now so I can get some time with it and make sure it doesn't accidentally screw with anything else. I've got another board on the way that's already got the two CAN...- Errol Smith

How To: Install a 2018 4C (UAQ/UAS) Radio in 2013 - 2017 RAM
Confirmed! I can turn my backup camera on and off via the CAN interface. I've got a dual CAN board showing up this week. I'll program it to read in the state of the reverse switch and automatically turn on/off the backup camera.- Errol Smith

How To: Install a 2018 4C (UAQ/UAS) Radio in 2013 - 2017 RAM
I'll want to run it in my truck for a while to make sure there's no weirdness with the CAN communication. If it all works, though, I'll design up an enclosure, list parts, and share the code so anyone can tackle this if they want.- Errol Smith

How To: Install a 2018 4C (UAQ/UAS) Radio in 2013 - 2017 RAM
I wrote an Arduino script that captured all CAN data for the first minute after it powered up and stored those addresses. It then filtered each incoming message based on the list of commands it stored during that minute. So long as I didn't touch anything, this filtered out all of the traffic...- Errol Smith

How To: Install a 2018 4C (UAQ/UAS) Radio in 2013 - 2017 RAM
Alright so unfortunately, @RockyAEV has an RA4 radio which is probably why his works. I was, however, able to find the CAN command to tell the backup camera to turn on. With the help of @Roman217 I now know the CAN message that's broadcast when the truck is put into reverse as well as the...- Errol Smith

How To: Install a 2018 4C (UAQ/UAS) Radio in 2013 - 2017 RAM
So @Roman217 has been helping me with CAN communication. We're able to get rid of the "Camera System Unavailable" message and replaced it with the "Check Entire Surroundings" message so that's something. Still not turning on without using the soft key but making progress.- Errol Smith

How To: Install a 2018 4C (UAQ/UAS) Radio in 2013 - 2017 RAM
Alfa doesn't show any changes in the Radio status and there's nothing coming in on 0x170 when I shift into reverse. Where'd you get the info for the CAN address anyway? I captured three logs from my CAN sniffer: 1) Neutral the whole time, 2) Shift to reverse shortly after key on and hold it...- Errol Smith
