It could be an interesting upgrade for someone if their Jeep came with just the basic radio, but for that much it really isn't worth it. I don't think you're really gaining much other than a flashier looking interface compared to the 430n or 730n, and I'm pretty sure those head units are much cheaper than $3500.
Insane Audio also has their android based JK1001 that costs about $1200 if I remember right. The cool thing about that is you can install any android app you want for nav, music, etc. I think it comes with a bluetooth OBDII reader that works with Torque Pro, but you can buy the same dongle and run that app off any cell for way less (IIRC $30 for the bluetooth dongle and $5-10 for the app if you don't get the free version), so if that's all you want it for it's not worth it either.
If you're looking for something that lets you display OBDII data and works as a programmer for tires, gears, tuning, etc, the best thing out there is a Trail Dash. Of course that doesn't have the radio or nav functions, but you can hook up a back up camera and use it as a switch pod for accessories with the optional wiring kits.
