Add me to the list!

U.S. base model with comfort access.

The system worked fine when I first started the car, but after driving for a few minutes, my satellite radio shut off completely and the No Signal message appeared on the screen. Then the system kept rebooting, even when I muted the volume and shut off the screen. Each time, the radio would play for a few minutes, then the no signal message would appear for a couple seconds, followed by a black screen for a couple seconds, the BMW logo screen, and then the Accept screen.

I remembered the method discussed on here to reboot the iDrive system, but holding down the volume button had no effect.

I haven't driven the car since, so we will see if it was just a fluke.

The only thing I did differently was I unlocked the car with the remote button rather than just touching the door handle. Not sure if that triggered this problem.

Unfortunately I am in this same club. I have a base model, with only the assist and enhanced Bluetooth. Some days the screen doesn't bank out at all, other times it will reboot with the no signal displayed up to 10 times.
I've already had it at the dealership twice for this, so far they haven't been able to figure it out.

Psycdude, sorry to hear that. Appearently, not only euro-spec 328i have this problem then

I would be slightly more relaxing to know if BMW is officially aware of this problem and is already working on a fix..

I have read this thread with fear and frustration. This has not happened to me, however now I am afraid to see this message every time I act to start my engine. I hope that the reason and solution to this issue is resolved in the near future.

After over 3 weeks of having this problem, I think I see a pattern in it. Should I drive from somewhere to somewhere, park there car and leave it for many hours, there is no problem at all upon the next start. If I park the car for a shorter time though (typically shopping around, stopping at the gas station, having a coffee and then driving away, etc), there's about 30% chance of hitting this error.

The question is, how this piece of information gets back to BMW and whether it helps or not (my guess is it'd be helpful though).

Same problem with blanc idrive screen

Hi, I encountered the same problem with the idrive system not always working and a blank screen. None of the idrive functions work.
It seems to occur after a second drive on the same day (within a couple of hours).
I went to the service center and they diagnosed that it is caused by the radio unit. I'm now waiting on the replacement of that for 2 weeks.

It's a F30 from April 2012 320D sedan.

Has anyone else who took their car in for service gotten anything resolved?

You mean a blank screen with the no signal message as shown in this thread or a complete blank one?

Sounds promising then.. appearently you're the first whose dealer seem to have any idea what could go wrong. I hope it's not a blind shoot

Quick update

When my car went into service they looked at my key and this told them I had lots of errors like DSC. They reset these and could not duplicate the No Signal message.

I picked the car up and within 2 hours I had the message again.

Took car back the next day luckily with the No Signal showing so they were able to diagnose. Again lots of errors showing

Hopefully they will fix or they might be getting the car back

LeaseDriverNL, any news on your case? I had a 20 mins drive today with the no signal message again - it quickly reminded me to get some piece of info from you.

Add me to the list... I only saw the message once so far, but once my iDrive spontaneously reset as well.

My fix is to wait for it to completely break or for BMW to put out a service bulletin before I bring it in and have the dealership do nothing....

I haven't seen the No Signal message, but my iDrive has reset suddenly. It did that after about 8-9 minutes I have started the car. Everything seemed normal before and after the reset.

Was wondering if U.S. owners with this (and any other) problem have been filing a complaint with the NHTSA?

I have seen the idrive reset once when it clearly got confused on bluetooth connections (my phone freezed during a connection attempt.

About the no signal problem, what I'd like to get is a confirmation that BMW is indeed aware of the problem and is already working on the fix. Oh, an ETA could be helpful as well.

Reboot-No signal

It happens to me when USB stick on. It keeps rebooting until taking off the USB memory stick.

Ozan, I guess the mp3 playing functionality of the software have bugs. Mine starts responding slowly for some mp3 songs. It may be relevant to how many songs there are in the folder songs being played. It may also be relevant to the encoding of mp3 files.

Does your problem occur while playing songs, or only when USB stick is plugged (even if you play the radio at that time)? If that is the case, the system may be selecting between different types of USB sticks. Can you try with another USB stick brand?

aarslan,

When I plug the usb stick, sometimes it starts rebooting after 1-2 minutes. Sometimes it reads it without problem. Even though, after stopping the car and restarting it, it plays 10 or 20 seconds and starts rebooting again. Switching to the radio doesn't change the result.
I've updated the system from 06 to 07 but it doesn't solve the problem. I'm taking the car to the dealer next wednesday. The lady on the phone has told me that another customer's complained about the same problem. So they will inform the BMW Germany

PS: I've tried 8gb and 32 gb sandisk...
