i bought my self a 2000 jeep grand cherokee, it has the infinity gold stereo system in it. i bought a single din touch screen radio and all the harness' i need for it. i tried hooking it up and the radio wont turn on. i went to best buy and had them just hook it up for me and the radio worked good until i took it out to tap the remote, and audio imputs in for my aftermarket amp im installing. everything was done right and when i put the radio back in and had everything together the radio didnt turn on. all my fuses are good. the ground is good. good connections all the way around. anyone have any idea what this would be? otherwise best buy is gunna get a rude phone call tomorrow. --..--:brick wall:
