I used to be really into upgraded car stereo systems until I wasn't. While their displays may be appealing, every single one I've seen or used in any of our other vehicles has been laggy, had a delay after touching it, worsened the sound quality, and most recently a name brand Pioneer Stereo in my Dad's Hummer H2 stayed on after the vehicle was turned off and of course fried the battery. They didn't warranty it either as they insisted it was due to "water damage/exposure." Therefore from now on in any vehicle, I'm sticking with factory. In a JK I'd look at some Mopar touchscreen stereos which were an option for the JK. More pricey but less problems.
