When you say refreshes is that a complete restart, back to the BMW splash screen each time, or does it startup and flicker?

Hi Cobra thanks for your reply.

The screen goes black and rolls up the screen quickly like a wipe and then is back again all in about 0.25 seconds. It is as if I degaused my PC screen.

It does not alter any function and the audio remains constant without interuption or noise.

Just this 9 second - timed it ealier today - refresh or blink of the screen.

I have also today upgraded the sofware to Version 28 and perspective view with all Europe maps, traffic alert and speed camera locations but the fault remains exactly the same - no worse - no better.

Any ideas?

John,

What is the NAV unit doing in the boot when the screen refreshes?

Does the eject light flash?

What happens when you revert to the Blue basic screen, ie remove the fuse to the SAT Nav, hence no power. If the screen refreshes on the basic blue screen it is not the SAT Nav.

must be a hardware related problem with the screen

Hi - have just bought a direct and perfect tested replacement for the Navi Monitor on eBay for $749 delivered.

Now I shall see whether it really is a faulty unit I have.

Hope it is to be honest because if it is not, I am back to square 1.

But at least I could sell the replacement unit again!!!

Hi DevonJohn

My e39 started to do this a couple of weeks ago......and i spent a long time trying to diagnose the fault. For me, it worked out to be the Traffic Master module....it would not even turn on.....and was causing the Nav screen to flicker every 9 seconds....

I found the harness in the boot which connects to the harness to the monitor at the front and just unplugged it....and that got rid of the flickering screen.

So if you also have Traffic Master module (you will have a TM button where the cup holders are supposed to be in the front) just disconnect the module from the harness in the boot!

Hope this helps you.................

Many thanks for your reply.

Was it really that simple??????

Did you blink happen exactly every 9 seconds?

I do indeed have the TM button to the right of the screen and like you - it doesn't work because I havn't subscribed to it.

Where abouts will I find the TM module and what does it look like? Do you have a picture or know where I might find one?

If this really is the only fault, I shall be putting that replacemnt Navi Monitor I have just bought back on eBay as soon as I get it!

I cannot beleive that a simple fault like that wouldn't be know by BMW!!!
