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!!!

Just to be clear for you iOS users out there.

If you have turned on "Show Notifications" in the bluetooth profile and the Jeep is still unable to read/display incoming text messages. You need to delete all previous text conversations from your phone, I know that sucks but it will start to work.

As for responding/sending text from your iPhone... It's not going to be an iOS-7 fix, sorry... Sadly I don't think this feature is going to ever be implemented unless the "iOS in the car" fails.
this works, this tutorial should be a sticky

kudos to you, sir.:):)
The 2014 RA4 comes with one year of service (Uconnect Access) RA3 comes with 6 months.

Im not sure if Ucon Access is required for it to read them, or only to send (which wont matter! lol)

as far as iOS and Siri... in the 2011 i had activating Siri was a major pain... would take forever for the car to see the BT connection. Now, its almost instant! Fantastic! Hit Siri and you hear the Beep through the car and the radio pics it up like its a phone call. Very nice
i think you only pay in the states, i live in guatemala and im still waiting for my jeep to arrive, but i tested it at the dealer btw (in guatemala you dont get the uconnect apps) but it worked as a charm for receiving messages, cant wait to get my GC :D:D:D:D:D:D
Any plans to add additional models. Seems kind of weak to promote a feature and then have it only work with one phone.
it works perfectly with iphone ;)
False. The iPhone doesn't support the voice to text feature.
at least it reads the text messages, and you can text with siri just through a long push on the button ;), im fine with that since i dont have the uconnect subscription in my country :)
