2014 JGC Texting Success

Hi all,

After delivery of my 2014 Grand Cherokee I was really disappointed when my AT&T Samsung Galaxy S3 i747 failed to work with the Messaging function on my radio. The Messaging button was greyed out and I searched fruitlessly for a workaround. Well, I'm happy to report I now have my Grand Cherokee reading my texts incoming out loud and I am using my voice to author new texts and send them out.

Here is a guide to rooting your phone: READ CAREFULLY

AT&T Galaxy S3 Rooting, ROMs, and Hacks - Android Forums at

This fix will require that your Galaxy S3 is rooted. You will need to flash the operating system to the following ROM:

The ROM is located here:


You will need to download Build 7:

Downloads - d2att-d2tmo -

Flash the ROM per the instructions on your ROOTED S3.

This ROM has updated Bluetooth MAP profiles that enable the texting functions to work on the radio.

DISCLAIMER: I assume no liability if you brick your phone. If you have never rooted and flashed a new ROM on your phone I highly suggest you do your homework prior to doing so as the result could be an inoperable device. Although flashing your ROM is easy and relatively safe it will void the warranty in most cases. Although I have never had any problems I consider myself pretty tech savvy. It is a very easy process as long as you know what your doing.

Oh by the way, I am loving the new functionality and now I dont have to get a blackberry! ENJOY and good luck!!!

Any plans to add additional models. Seems kind of weak to promote a feature and then have it only work with one phone.
There are lots of supported models... outgoing text simply is not working properly on this software revision. There are updates coming to make it work better. Then I can get into more info on models when they update.

Some iphones work some don't depends on carrier. Nothing in texting is working correctly right now though.... :(
Seeing if anyone else has this...when I pair my Galaxy S3, the message box is no longer greyed out, and it shows all of the current messages on my phone. Problem is, new messages aren't received. My carrier is Verizon, and just not sure if it is carrier, or phone related.

In this case if you deleted your message history and limited your conversation history to **I Believe** 20, then it will work. Simply a work around at this time, I expect longer than a 20 message history should be supported at some point in the future.
They are still having challenges getting anything but preformatted texts to send.
My iPhone 4s is paired with my uconnect 5.0, but after getting the radio replaced by Jeep, I can't get it to download text messages. I had it reading texts before radio was replaced. Any suggestions?
Check the Version number in the radio... let us know what the Software Version is.
I have the Samsung note 2 and before I got the 13.19 update it worked. I was able to reply and it read the texts to me as they came in. After the update it only loads the texts that are on my phone. Any idea when an update is coming out? I heard it was supposed to come out today.
Yes, it has been confirmed that outgoing texts have been rectified in the next release. It appears that this release has been put off for 1 to 3 weeks at this time.
where do i find the version #? I looked at all the possible settings an did not see it.
On an RA2 you must be in "Dealer Mode" PDF attached is the update instructions but gives you the easiest way to see the information.


Will outgoing texts be implemented for iPhones?

I am wondering if the problem with outgoing texts is related to the encrypted connection part of the bluetooth Message Access Profile spec?
It is being corrected for all platforms tmk.
