Hi @15jimenjos,

Full disclosure, I've not done an upgrade from my 2014 TH uConnect 8.4 to the 2019+ CP/AA version (I upgraded to the T'EYES CC3 Android unit) however I did recently do a non-2019+ upgrade from 4" uConnect without NAV to an 8.4 non-NAV unit and the Radio Type setting needed to be at Type 3 (I think Type 4 is the NAV unit).

• First thing #1: GREAT you're in the habit of making a backup. Do that before each change. Kudos! Also, since you have a 2019+, you're using the Security Gateway Bypass cable, correct? (else none of your settings should be writing. In fact, I don't think you could even do a proxi align w/o it)
• Next (#2), Is there no sound or when you turn the volume knob, do you see the on-screen volume indicator move but the actual sound from the unit doesn't change? If so, first thing I'd do is let your Cherokee sit over night and then try again tomorrow. Many settings for the radio are stored in the body computer (like your heated/vented seats) and the unit must go to full "sleep mode" before everything works so I'd check everything in the morning.
• Next thing (#3), I'm not sure you can keep the old media hub in there and not get an error. It sounds like right now you have 2 media hubs, the old one above the shifter and the new one you're keeping in the center arm rest daisy chained from the first hub. Is this correct? Did you connect 2 media hubs? If so, of course you could be getting an error just from that. I'd fix that or shut if off (see below in AlfaOBD). For testing purposes, plug the new hub directly into the back of the new uConnect.
• Also, make sure you have the audio type (standard ("Base") 6 speaker or Premium, 9 speaker, correct)

These are just a few places I'd start. Again though, wait until the car sleeps (and you too!) Then tackle in the morning and see if not working still and then just address those items.

Perhaps someone with a 2019+ and AlfaOBD can confirm what the external media ports configuration should be?

Thanks for the response Gary Kline.

1- My vehicle is the 2017 Cherokee.

2- When I turn the volume knob the indicator on the screen moves, but I get no sound. I will let it sleep as you recommend.

3- For the USB Hub, I'm not a big fan of having a bunch of wires laying around so I found out that for a 2019 Cherokee you can connect to the single usb slot that is in the center armrest storage for CarPlay. I figured it wouldn't be much different if I replace this instead of the one above the shifter. The problem I ran into is that my original usb slot in the armrest storage area was hardwired into the hub in the armrest. So what I did is I ordered a double sided USB mini cable that would connect the new usb slot from a 2019 jeep to the other end of the connection. The media hub above the shifter has two USB Mini connections on the back of it. One comes from the Uconnect and the other runs under the shifter to inside the armrest where the other usb is in my vehicle. I took apart the shifter and center console area and ran the new wire from new hub in the armrest to the media hub above the shifter. The wire is actually long enough to reach the connection all the way up to behind the screen with a little bit of feeding it through, but I'll only try this out if I can get some of the other things sorted out. Hopefully I don't have to and the CarPlay works like this. The new armrest hub I got from a 2019 has been working perfectly to charge my phone and even pops up as iPhone when I switch to media.

Also I did change to the Radio Type 3 and will let it simmer overnight along with the other changes I had already made. Fingers crossed!

Thanks a lot for the response!

No problem. Re: #2 above, it still sounds like the stock daisy-chain. Maybe I'm misreading what you wrote. Stock, a mini USB plugs into the back of the radio (gray connector) down to the Media Hub (above the shifter) and then runs from there to the center console port. Are you saying you found a long USB wire and got a 2019+ media hub and wired direct to the gray connector on the uConnect radio? (so the original media hub and its wire are still there but just not plugged into anything.)

 

[Gary Kline]

Sorry. I misunderstood the daisy chain thing, but it sounds like that is what I did. I could plug in direct and let the other one hang as I don’t ever use that hub anyway, but I’ve left it as the daisy chain deal you mentioned.
So you think I do have to replace the one above the shifter still?
I just figured CarPlay wasn’t working yet since the ECU was still failing during the Proxy Alignment.

You can't really address the CP issue until you can do a proxi align and the odometer stops flashing (the 'fail' you're getting on the Telematics Module is the uConnect radio) so until you can get past that you can't really address the CarPlay.

But if even for troubleshooting purposes, you should bypass the old media hub and only hook up the new one, even if just with a wire sticking out of the dash for testing.

“Hi, were you able to solve the audio problem? I’m having the same issue. I bought a TOMYD series radio on eBay, ran the proxy alignment, and it worked but there’s no audio. My Jeep is a 2014 Trailhawk.”

Hey @Geraham,

Not familiar with a TOMYD radio but was it plug & play with the Jeep's wiring harness? Also, after running the proxy, have you let your Jeep "go to sleep" for 10-20 minutes and then try again? On a replacement radio, right after running a proxy, some parts can appear to not work. For example, the volume may not work from the knob... you see it volume control graphic move on the screen but the actual volume doesn't increase/decrease as you move adjust it. Assuming the radio harness was correct, it was a radio that was designed (or spoken about here on the Forum as working in a Cherokee and, the Cherokee has gone through at a least one "sleep cycle", it then works.

 

[Gary Kline]

Thank you for responding!
Yes, the radio is plug & play. After doing the proxy alignment, I left the radio connected for a couple of days. The reverse camera worked, the knob raised and lowered the volume (no audio), and the pink connector was the only one I didn’t connect.
It gives me the following codes:
Error code: B1400
Front Left Audio Speaker Output
Open circuit
Error present
Error code: B1404
Front Right Audio Speaker Output

Hi @Geraham ,

1. Is this radio in the photo your new one or your old one??

2. The pink Fakra connector is for Satellite radio/GPS antenna. That won't affect your volume but I'm curious when you wrote, "pink connector was the only one I didn’t connect". Do you have the pink connector in your Cherokee and you didn't connect it? If the photo above is your OLD radio, where was the pink connector connected to?

3. I'm still not sure what "TOMYD" means? ( "I bought a TOMYD series radio on eBay") Can you upload a photo of the radio you bought? (I'm assuming the one above, a Mopar VP2, was your original that you removed, correct?)

 

[Gary Kline]

Hi Gary,
the photo I sent in the previous post is of the new radio (2019 Cherokee) VP2, with which I did the proxy alignment.

I’m sending you a picture of the current setup of my 2014 Cherokee; it’s a Harman VP4 radio.

No, the previous photo is of the radio I’m trying to install.

Hi @Geraham,

So you traded an 8.4 inch VP4 radio for a 5 inch VP2? And this was to get Carplay/Android Auto?

if so, there's other things that need to be done to upgrade to a Carplay radio. The USB Media hub also needs to be updated and I think the HVAC control module. There are a couple folks on this Forum who recently upgraded to a 2019+ CP/AA radio that may comment.

Just to confirm though, you traded from an 8.4 inch color screen to a 5 inch black and white, right???


VP4

VP2

 

[Gary Kline]

The VP2 is 8.4”, and I believe I have everything necessary to do the upgrade, but I’ve had the parts stored for over 6 months.

Do you think it could be related to not installing the USB module? Could that be the reason I have no audio?

Hi @Geraham,

Question... are you saying you have all three pieces (radio, HVAC module and USB hub) and didn't install all of them? If so, I would complete the job first as the issue could be from just an incomplete setup. If all three pieces are installed and it still doesn't work, then I would suggest looking at other potential causes (for example, there's a setting in the Body Control Module that specifies the type of radio in the car. We use an app called 'AlfaOBD' to change it).

First however, get everything hooked up and see if the issue resolves itself.
