Car stereo can't connect to One X by USB cable since upgrading to Jelly Bean
Originally when I got my One X I was able to plug it into my car stereo through a USB cable and the phone would act as a mass storage device. I would then navigate through my songs using the stereo's remote control - I could navigate through songs using the back and forward arrows, and through folders using the up and down arrows. Similarly when I plugged the phone into my computer I had the option of treating it like a mass storage device as well.
When I first bought the phone I believe that it had Android 4.0 (Ice Cream Sandwich) installed, however I recently installed the Android Revolution HD ROM, and since installing it my car stereo is unable to read from the phone using a USB cable. Furthermore (and I believe this is related) whenever I plug my phone into a computer I am presented with "HTC Sync App", and do not appear to have a mass storage icon under "Computer" (or "My Computer").
Here are the full details of my ROM (and firmware) version:
Is there an app or a tweak of some sort that will allow me to connect my One X as a mass storage device to my car stereo again?
Other than this short coming the new ROM is an excellent innovation.
Any help will be greatly appreciated.
