Computer screen freezing

For no apparent reason, the computer/sat nav screen has started to freeze 5 to 10 mins into a journey. The controls have no effect, turning off/on using left hand knob has no effect. Does not matter what screen is selected (menu screen, sat nav, computer) it just freezes. What is strange is that the small read out in the speedo continues to work, so you can still see outside temp etc. which suggests OBC system is actually OK and proble is with display. Once ignition turned off/on, even for just a moment, results in it working again, for another 5 - 10 mins.

Until last few weeks, it has performed without issue.

Any ideas, could there be a loose connection somewhere ?

Any help appreciated.
 
Mine does the same now and then, but BMW have yet to replicate the issue in the 10 minutes they look at it each time.

It's so infrequent that I've gotten used to it, and I'm normally using a TomTom 1005 for directions/speedcams anyway.
 
It is not just sat nav that freezes, it can happen in mian menu, or the computer screen. It happens with the real BMW sat nav disk loaded, and on on every journey. :(
 
I have this issue every few months too. It is still possible to select between radio / multidisc CD / dash CD, and tune the radio, even thought the screen remains blank. With mine, the car needs to be switched off for at least 30 minutes to allow the system to entirely power down.
 
That sounds like it, blue tooth and radio/ipod continue to work.

Regarding 30 mins, do you mean disconnecting battery for 30 mins solves the problem for a few months ?
 
Hi Guys. I've had this same problem in the past and BMW ended up having to replace something to solve it. I say something as it was not the screen, headunit or DVD player - plus it was under extended warranty so have no paperwork. In my situation it was the same but it only happened when on a certain road. BMW couldn't replicate it the first time round. I had to record it happening and provide BMW with the recordings then it was plain sailing. That's what I would advise to you mmm five.

Hope that helps. Jamie

No, just switching off the ignition is enough. I believe some systems remain powered for sometime after the ignition is switched off, and certainly that would explain the need to leave the car for a while before it will reset. It may be necessary to lock the doors too, as unlocking initiates the sat nav (so it will be available to use immediately when the ignition turned on).

With mine, the problem is extremely infrequent so I'm not prepared to pay for it to be investigated as yet...
 
Mine is now also doing this! As of this morning.

The radio etc controls still work but the display is frozen. It revives immediately if I turn the ignition off and on again.

Haven't had a chance yet to spot any pattern to the occurances, but it was pretty repeatable for me (5 or so minutes after turning the car on, each time).

Maybe tomorrow it will be in a different mood...?
 
Er... he might be?... ?...

(If this is some reference to a previous thread on the topic that I should have found before posting - apologies - I looked and didn't find it! :) )
 
Once in a while you'll come across a reference to "Flimper spec" (usually on a thread that he's contributed to). This means not having sat nav, and vehemently protesting that you wouldn't want it anyway :D
 
Ah OK, I get it!

Anyone heard of the problem, or has it currently? Hopefully next time I drive the car it'll be gone again... ghost in the machine... but... :)
 
I have this problem too on my 2004 Z4. Radio, cd-player and everything else works except the screen. The screen remains blank until I restart the car. Sometimes it doesn't help and I have to wait like 30mins to get the screen back on. Sometimes just switching the radio on/off helps and the screen comes back on. This problem happens like once or twice in a month. I think it has something to do with the dvd-player and the non original navigation dvd.
 
Hi,

Firstly am ashamed to say this is my first post but been lurking and learning for over 18 months as an owner of an Imola M Coupe.. Great forum btw...

Anyway on my way back over the Pennines my sat nav started to behave as described above, eventually it rebooted itself partially then froze entirely. Didn't pay much attention first time thought it a one off, wouldn't reboot on the key but ok on startup when left overnight. Not a glitch though as occurred 2-3 times in quick succession.

I have an OEM nav disk but its an old version now @ 2008 might an upgrade help (I hate the fact is partial postcode input anyway) or for those that have had these problems was there a common root cause.. All help appreciated. Oh and my rear PDC has also packed up in sympathy ....
