You may need to get the traffic update but your radio isn’t helping. The car radio then plays the signal through the car speakers. The antenna captures the radio signal and sends it to the car radio. The car radio receives its signal from the radio antenna. The battery supplies power to the car radio, and the car radio powers the car speakers. AM and FM radio carry sound waves-a type of analogue signal to your receiver. And FM radio maintains a constant amplitude while the frequency varies based on the overlaid signal. AM radio broadcasts a carrier wave that maintains a constant frequency, while the overlaying sound wave modulates its amplitude. There are two ways radio stations modulate their carrier waves: amplitude modulation, or AM, and frequency modulation, FM. Radio signals are electromagnetic waves of frequencies ranging from about 30 kilohertz (kHz) to 300 gigahertz (GHz). The term “radio” includes both the transmitter and the receiver and is derived from the Latin word “radius,” meaning “ray” or “beam.” In 1892, Italian inventor Guglielmo Marconi developed the first practical radiotelegraph system.
Radio waves are the longest electromagnetic spectrum waves that carry information from a radio station to a receiver. Frequently Asked Why Does My Radio Turn On But No Sound Questions:.Why does my radio turn on but no sound?.I would attempt to read the rad file from the new radio first. Would be the same as this except you want option 677 for logic 7

Some of the above are for idrive you want the ones for pro radio. I believe you can do something called and sgreset for the 2urad file in Ncsexpertįor the radio and it will reload the factory presets that are stored You can read the 2urad file to see what the radio is set up for. Go to the coding subforum here look up coding for the radio.

You can get from ebay some, but you'll to code it to your options - sirius, tcu and amp If it is not - then MOST GW in radio dead and you need to replace radio Insert quadlock connector back and check, if radio will emit red light Since it is quite easy to remove radio you can do following Is there a reason I don't see the red light in any of the components in the trunk? Something that could point to as the problem?Īnd, I CAN eject the CD from the player, so the radio seems to have power Is there more than the four components in the MOST bus, the three in the trunk-amp, tcu, and satellite and the head unit? But I'm not seeing light out of the connectors which is shown in the video, that why I was thinking the head unit, because I haven't pulled that at this point. Thank you for the response ctuna, I had seen this video, that's when I got the loop connector and tried to bypass different components. Sorry for the late reply, been out of town. I read somewhere about pulling the head unit and looking at inside the unit from the side and if there is no led light, then its dead? I have checked some fuses, but what are the main fuses I should check?įrom what I've read, seems to be either the TCU or head unit, I'm thinking head unit because of the no red light? But not sure, I have not pulled out the head unit yet, but wanted to see if there was a way to tell if the head unit is bad vs. One thing I did notice was when I had the connector disconnected from the TCU, amp and satellite radio and the car was on there was no red light and in videos when people were doing some testing it seemed like there was a red light coming from the connector? I bought one of those MOST loop connectors and tried to bypass the TCU, satellite radio and amp, but nothing changed. while playing with the volume, still nothing Pressed the button to switch between aux/cd/radio etc. I have held the menu button for 20 seconds, pressed the on/off button for 20 seconds and sometimes just a quick click on/off but NOTHING. The lights around the radio are on and I can eject the CD, but the screen is blank and no sound.

I have the BMW professional radio WITHOUT idrive, I think it has Logic 7
My battery was having issues and finally died(thought this might be the issue), but replaced the battery and used INPA to reset it and still no screen, no sound and SOS error One day my radio was working, now it is not and giving an SOS error. So I've had this issue before and it kinda just went away.
