Only ever happened once with my brand-new 750i, and the screen was orange. After turning off the car for a few hours, the issue seemed to be fixed on its own. I attributed it to the requirement for a computer reboot in the car. In almost 18 months of ownership, I never again encountered this. Definitely seems like a computer issue—possibly not initializing with all of the vehicle’s programs. It’s time to return it to the seller.
Anyone else experiencing this problem? The sound system will abruptly stop working and a NO SIGNAL sign will appear. The head unit will either automatically reboot itself or make a POP sound to signal that everything has returned to normal. It has occasionally occurred (4 times so far over a year).
Yes, I’ve experienced that problem too. Approximately twice since January 2015. It appears that the iDrive kernel simply panicked and rebooted on its own. The software was updated when I recently took the car to my dealer for the first scheduled maintenance. Check to see if it occurs again.
This morning, the “No Signal” notice appeared on the iDrive screen. After entering the car using Comfort Access, it happened with the power on. The system did not reboot on its own, and turning the car off and on had no effect. I quickly searched and discovered a lengthy thread about this in the F30 forum.
I tried the workaround that someone advised: depressing the radio button for 30 seconds. Rebooting the device will restore regular operation.
I’ll keep an eye out for it because this is the first time in a year that it has happened. There are a lot more occurrences in the F30, but I only discovered 4 more brief threads about it in 2addicts. I’m not sure if a solution was found. Anybody else experiencing this? Is there a fix?
I can’t remember the last time I received a NO SIGNAL since my last post. At least I haven’t experienced that problem again in 2017. My iDrive, however, is an older model than the iDrive on cars made in 2017.
This occurred to me this morning. The situation was not resolved by turning the automobile on and off. But as soon as I started leaving my house, iDrive started working again. In addition, I observed that while in my driveway, my phone was not connecting to WiFi as usual. Therefore, I think the system hanging was caused by WiFi or Apple CarPlay…
How long did it not work? I experience this around once every two months. According to what I understand, iDrive simply reboots and displays “No Signal” when it’s offline. For me, it always comes back on within 1-3 minutes. I spoke about it with the BMW service staff, and they basically told that something must be producing an iDrive error, and it reboots to fix the problem. They informed me that in order to identify the problem, they would need to look through the entire system, and since my CPO warranty does not cover any iDrive components, I would just have to put up with it. Although I had this problem long before I added the ASD bypass, I know they would attempt to blame it on that because I have it placed on the amplifier.
On my way back to work today afternoon at 12:00, the car displayed this, but other than the screen not showing an image, everything else worked as it should, so I drove it there. Has anyone else ever had this issue?
After arriving at the office, I attempted it, but nothing happened. But after turning off and restarting the vehicle, everything returned to normal.
Although I am aware that this is an old topic, the battery turned out to be the cause of my problem. The iDrive reported the “no signal” issue because the head unit wasn’t communicating on boot, according to what the engineer claimed. It appears that the head unit wasn’t powered up until the alternator engaged.
I took it in for repair since I was experiencing further issues with the battery “discharging.” The “no signal” issue was resolved by changing the battery.
My BMW’s screen is black; why?
The blank screen is a frequent issue, and it usually goes away after restarting the car. Since you are still covered by warranty, bring it to the dealer.
Why is my car’s display malfunctioning?
The display unit in your automobile can have problems as a result of a bad fuse. If you’re unlucky, a blown fuse will prevent your car stereo from turning on when the ignition is on. A somewhat old but still efficient method of preventing short circuits is the use of fuses.
Additionally, your automobile may have had a fuse installed that was intended to prevent a sudden short circuit from damaging your radio. Your automobile radio display may not function due to a faulty or damaged fuse.
The display unit and the power wire are directly across from this specific fuse. If you replaced the standard stereo with a more modern one, there may be a problem where the aftermarket stereo won’t switch on because of a blown fuse.
So it seems sense that if the fuse blows, the power would cut out. You might be experiencing issues as a result of the fuse blowing while you weren’t there.
