The touchscreen in my 08 jku is no longer working. The screen is peeling off and the touchscreen is no longer working. Im looking to replace it with a single din head unit, but on crutchfield they say I need a $129 adapter to make it work since I have the Infinity sound system. Is this adapter really needed? What have you guys needed or used to replace your factory head unit? I dont mind shelling out a few hundred bucks for a new stereo, but $129 for an adapter seems a bit steep. Thanks in advance.
