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:

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!!!

I have an HTC Rezound and the messaging feature on the Uconnect does not work (greyed out). I went into the phone settings to Bluetooth/Menu button/Advanced/Check box labeled message access. I did get it to work once but no luck thereafter. Back to greyed out. Has anyone been able to get the HTC Rezound working correctly with the Uconnect messaging feature?
Are there phone models that work 100% with the messaging feature the way it is intended? Please post your model if it works with all the uconnect messaging features.
Any plans to add additional models. Seems kind of weak to promote a feature and then have it only work with one phone.
Has anyone had any luck with the HTC Rezound on VZW?
