Navigation & Stereo Issue - Needs Your Help

I own 2007 650i Convertible. I just love this car.
I am recently having a minor issue I would like to resolve. The navi and stereo all works fine, but while I am driving, the navy and stereo system resets by itself once in a while. The screen goes black all of a sudden, about a minute later it displays the BMW logo, and the system comes back working fine again. It happens randomly once in a while.

Did anyone experience the same thing and know the fix?

THANK YOU, in advance.

Sounds like something is loose. I might try to get in the dash and check the connection.

You might also try resetting the thing yourself once. Push both eject buttons (DVD/CD) and the volume / mute button at the same time. iDrive will reset itsef.

But it sounds like that is what is happening to you already. No harm in trying. Good luck.

Thank you. I will try it - anything helps. I am glad I posted the issue. I will update the result. Thanks, again.

It could also be a bad NAV DVD. I would try ejecting the DVD and wait a few days to see if that clears the issue.

It happens on my 7 series on early morning drives. The strange thing is that it only happens on left hand turns. I have read that it is a symptom that is related to the CIC module. When it throws a code, I will find it. Until it fails, I will learn to live with it!

You are not alone!

Thank you, all.
I will update you when I find out also.

Also you may have a battery problem if the battery is not up to par in your car. I read before that the NAV and iDrive usually show indications first of a battry dying first. Try the suggestions given by the other members first because it cost nothing, then if you haven't check your battery, try that.

You might have a valid point here, mine has not acted up since changing the battery 2 months ago. I had not realized this until this post. I hope I don't jinx myself!

It's amazing how the gremlins creep into these cars when your battery power starts to get low. A friend of mine has a convertible and was dredding the "Top Not Lock" issue when the error popped up. At the sametime his battery was getting weak so he did the battery replacement first. Since he did that, the top not lock error never returned. These cars are sometimes hard to figure out man.

Sometimes!

Hello gents I have a few issues on my 2004 645 ci,that I believe are all linked some how; my voice navigation doesn't work, I only get one radio station, and when I try to select my bluetooth it doesn't allow me to select it. Any ideas on what this could be? Don't really want to give the dealer $200 to diagnose this.
