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!!!

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.
Thanks, I will give this a try...hopefully updates to the system will allow for more messages.

update: So I deleted all messages from my phone, and had someone text me. nothing...I shut off the jeep, start it back, and there is the text that I already read. Is anyone else using the S3 on Verizon and having this successfully work?
