All buttons not working screen is frozen plz help it fixView My Video

Pull the fuses for the Nav. They're in the boot, right hand side panel as you look in. Leave them off for 30 minutes and replace.

If it's still frozen then the cheapest fix didn't work.

From all block or only from nav. ? Becaus i see 3blocks nav, cd changer, and more one black on bottom

The fuses are the other side of the boot.

The video shown is not of the nav screen but the tv module it has taken over running the show as your nav computer has thrown a wobbler i would disconnect the battery and try again.

I pull out nav. Systemem fuses ( 7; 72; 73) but in boot i found only 72 and 73 fuses so i pull out them for all night in morring i put them back and screen still frozen but then turn ignition on music not playing and no sound but if i start engine on then music start playing but i can still control the screen buttons not working only on steering-wheel i can switch radio station but after 1-2min of playing then engine on music whit sound gone and i have shut down engine and ignition off and agen start engine fot play music and agen its gone after 1-2min... More info on video so more suggestion how fix it ?View My Video

If the nav module fails, then monitor screen will usually be white/snow/blank with possible with a hint of backlighting. If you unplug the nav, then the TV module, if fitted, will take over the display and show an old style display in blue with white font. However the 2 min cut off is a known symptom of a failed nav in other series beside the E53. Nav replacement I'm afraid

So i need new nav.modul in boot ? or all new screen ?  :'(

Nav computer in the boot only as the video feed seems to be OK and the head screen is also OK.

Richard

So what i need do now to fix it  ?

You need to look for a replacement on line (Mark 4 Navigation Computer), or buy one from BMW for a ridiculous price.  Alternatively take your existing unit out and send it for repair.  There are companies on line who can do it for a lot less than a new one.

Ok i will try get new or used for bmw original used parts or find who give only test it engine not important for nav compiuter ? only year and module of bmw ?

Yes.  Either a CD type Mark 3 up to 2003 facelift date and then it's a DVD type Mark 4 version.  They look the same.

This is what you need.

I can remember, these were over £400 not so long ago, so looks like a good time to buy.

So i changes nav system for e53 to e38 (e38 nav system working fine) so e53 block is working fine in e38 all controlls working on screen and buttons but e38 nav system block is not working in e53... so its not nav system block so who can be more ? : :blink:
