BMW X5 E53 Sat Nav Screen Fault?

Hey Guys,

Just joined the forum and looking forward to catching up with all things BMW. I've got a very tidy 2005 Carbon Black X5 (E53) 3.0 D sport which I rather like but its developed a curious fault with the built in 16:9 Sat Nav Screen (Mk3 or 4 - not sure how to confirm which) which intermittently flickers/flashes off for less that a second and then is fine again. No systems are interrupted so music or radio continues to work and respond and the Sat Nav continues to guide. Often you just catch it flicker/blink out of the corner of your eye - blink and you'll miss it kind of speed. I've removed the unit and checked the ribbon cables and attempted to clean both those as well as any other electrical connections, and also gone in the boot and attempted to 'waggle' any cables from the DVD drive etc to try and force it to flicker but I've not had any luck narrowing down the issue. The only other thing I've noticed that although the Digital TV feature attempts to find channels nothing is found. Just wondered of anyone had any suggestions? Could it simply need a new screen/unit or could it be something like the TV tuner which I believe everything goes through before it reaches the screen? Really appreciate any advice!

Cheers,
Alex

Hi Alex,
Did you ever find out what the issue was?
I’ve just replaced my sat nav screen as it had the lines across the unit.
It always flickered so I thought the new screen would solve the flickering issue but I was wrong.
Look forward to your reply.
Cheers Danny

Interesting, sounds like the same problem ive got. Screen dissapears & rarely comes back. I have another X so changed head units over & DVD navigation computer & tuner. Still have this problem. Iíve also scanned the car with ISTA & the only fault it finds is communication with video module. I will troubleshoot it further & keep you updated.

Update, definitely a tv tuner issue as well as something else.

Plugging the Nav directly in to tuner location as suggested in another post does nothing even with a known working NAV. Putting in a known working tuner also did not resolve the issue for me so there has to be another component in the loop causing this problem, I have checked all wiring and plugs and all is good there.

I can also confirm in my case, the Navigation does not run the display, the tv tuner does once the white plug is connected. This is the case in both my facelift X5s.

Very puzzling 🤔

Hey X5F,
I’ve sorted mine out after even swapping heads that didn’t work.
The issue was in the boot there’s a blue connector from the T.V module to the sat nav head unit, if you disconnect this connector you might find black sticky stuff which has come off the electrical tape over hot summer years and ran into the connector!
I sprayed some WD Electrical cleaner in mine, put it all back and no flickering.
I hope it’s the same fix for you ����
