Ok I'm new to the forums I hope I'm posting in the right spot so I have a a '05 G35 coupe 106,000 mi on it. It has the factory alarm or whatever. You know it locks unlocks rolls the windows down all that stuff. I took the radio out one day cuz I was headed across to another part of town to buy a aftermarket radio bezel that had the climate control in it right so I get there. It's not the right thing or he didn't have the pigtail for the climate control or whatever dude tried to tell me it was available at O'Reilly's but I knew better than that so I don't put the car radio back in at his house. I'll wait and do it when I get home so I get home. I put the radio back. I plug everything in just like it was. Everything works. However, when I turn the car on that time after putting everything back in. I looked over and noticed that this light on my dash was blinking that I never noticed was blinking before. It may have been but I doubt it. I'm pretty observant and getting in and out of the car when it's off. It's blinking so I'm blind. If I don't see it you know. So it blinks as if it's a car alarm and when I get in the car and I crank it up, there is a loud wine that comes like a. I can't explain it really. It's like a buzzer. It's like it's something that's not supposed to be there. I know that I can't really look far under the dash to see if there is a box under there. However, I do see an aftermarket relay stuffed up under somewhere near about where that LED is. I can't find any videos or any how to's on how to remove the how to remove the air vents and the stuff around the air fence and then I could just trace the wire to wherever it goes. And I have my answer. It doesn't have remote start that I know of and I've never been told that and I've never noticed. But like I said, it's making this noise now and the LED blinks and it it has absolutely no function on the car that I can tell I've got a video. I'll post the link if we're allowed to do that. It'll be a Google photos link to the video and you can hear what noise it is. And if anybody's got any new ideas, I'd appreciate it. No, I don't see anything plugged into the relay box at all. No nowhere not under the hood. Not under the dash nowhere and any of the three. Actually I'm going to do a video right now. I'm going to upload it

Any help would be appreciative and if anybody knows how to remove the little trim over here around the side air vent, I'd appreciate it. I tried to pop the silver trim piece like you do when removing the radio and that piece did not want to come out. I swear I was going to break it if I tried harder. Thanks in advance
