Hey Guys! So I recently purchased a 2011 Jeep patriot from a dealer used. I recently ran into an issue with my radio. The other day I went to start up my car and my radio just stopped working. The unit display still functions properly but I can't switch between cd/radio/aux. The volume control works on the display but only when I turn the volume knob down. The weird thing is that when the system isn't working i'm getting a popping noise from my speakers. The volume of the popping noise varies but it is pretty consistent, about every 5-6 seconds. I called the dealership and they didn't have any useful insight on my problem. Before I have to take it up to the dealership I wanted to check and see if anyone on here has had a similar issue or not. Or if any of you have heard of this before. I feel like it might just be a defective radio. I checked all of my fuses and none of them were blown so I'm a little confused as to what the problem could be. Thanks guys!!!
