MID/Nav display not working after battery jumpstart

[Kisu_san]

recently i had to jump start the car because of bad alternator. I replaced alternator. But MID /Nav display is not working. CD, Radio etc is working fine though.

Actually I turned off the monitor before the jump start. Does anyone know how to bring this back to life. I thought pressing Menu button will do ...but it did not.

All fuses are fine....

Help pls

you mentioned that the fuses are good... that includes F75 for the monitor... You mentioned that you TURNED off the monitor - can you tell us what procedure you used to turn the monitor off?

also, when you say MID, you still refer to the monitor, right?... it is clear that you have Nav - do you have TV module as well?

I am trying to gather as much info as possible, as there are many possible configurations of the systems...

when you turn the car on, the radio is on, you are able to change the stations using the buttons on the monitor, right? when you change the stations using the steering wheel buttons, do you get the station numbers on the cluster display in the odometer panel?

when you press the MODE, you are able to get the CD to work, and you are able to change disks and change tracks, right? when you do it from the steering wheel, can you see the changes in front of you?

at night, are you able to see any faint glow on the monitor, or the monitort is totally dark?

at bright daylight, when you look at the monitor, are you able to see faint pictures of the nav, or the other info? or the monitor is dark as well?

try to answer as many questions as you can and don't be afraid to put out as much information as you can - remote diagnostics across ocean is rather a difficult task...

Yes I checked F75 in boot. In fact I checked all the fuses in boot. They are good

Press "Menu" button and then select "Turn off " option on screen by turning knob.

Yes, I refer MID as monitor. Yes it has Navigation but not TV

Yes, I can change CD/Radio and tracks using button on Monitor and on steering wheel. But nothing display on monitor or odometer panel. In fact it never used to display station information on odometer panel. Only date/time, etc. But problem is now I am not able to set time/date etc also. because in order set these value I need monitor set option.

Yes I can change but no display

I can see some glow at edges, not much though

No nothing at all.

Car Model:
BMW X5 E53 2002/12 3.0i European model
Got Navigation, CD/Radio/Cassette

since you can see the glow at the edges, i suspect the issue might be with the Nav computer itself and not the monitor... when the car is waking up, can you hear the nav unit spinning? is the nav computer running at all? can you visually confirm that the red light is on and hear that the disk inside is spinning?

I am trying to remember if the nav unit has its own dedicated fuse on board or on the back panel...

if the nav computer is not showing signs of life, chances are, someting is fried inside...

if the nav comp is spinning, huffing and puffing, then for some reason it is not generating the main menu screen - the front monitor seems to be ok, you are able to use the front buttons on the monitor...

the nav computer not generating the main menu can be due to internal issues, such as burnt circuit, or to external issues, such as broken/loose/chaffed wire, such as an iBus wire. if I am not mistaken the iBus wire is yellow with brown tracer... but, your issues started with battery jump, so i would not think it is related to the physical issue with wire, more likely to electrical issue with the unit.

one of the ways to figure out if the nav comp is working, would be to inquire/interrogate the nav module with the software, such as INPA, or PA Soft... if you do not have the software, i may suggest investing about $40 into the cable and software, there is a seller on ebay, from romania, he sold the cable and the software to a few members on this forum...

another way to test the nav, pull it out and cross connect to a known working car to see if this unit will generate the menu, and at the same time, take a known good nav system, and connect to your car, to see if anything will be generated for you... you can also try to connect a TV module - in absence of nav computer, the TV module will generate funky looking main menu

this excersice will establish of the monitor is indeed operational, as i suspect it is,

and, if the nav computer is functioning, as i suspect, it is not...

assuming that there is no break in wiring... was there any physical work done in the trunk/boot? like, did somebody replace the battery? or, installed a Bluetooth unit? or replaced/installed CD changer? or removed spare tire? or did work on the airsuspension?

sorry for mumbling - trying to brainstorm your issue here...

My dump question:
1. Is the DVD Nav drive is that Nav computer? Or just a DVD drive?
2. Is this responsible for generating Nav Screen and other normal screen
Where you have computer options like mileage/petrol consumption etc

I will disconnect and reconnect DVD Nav in boot.

[TerminatorX5]

the nav DVD drive is reading only map DVDs, not movies or music... the Nav comp/DVD drive is responsible for generating menu picture on the monitor. in absense of Nav comp and presense of TV module, the TV module will generate the menu, in presense of both, Nav and TV modules, the Nav takes over the picture generation.

I thought that the High computer option (S555) was generated by the IKM/KOMBI module, the speedometer cluster with alphanumeric display, but it was proven on this forum that sometimes it might not be case... i still think, that the fuel consumption is generated by the cluster but it might not be correct...

[bcredliner]

I would try pulling the fuse to the navigation or unpluging it and leaving it out for 20-30 minutes and reinstall. That should reboot the system. They reset procedure for iDrive is hold down dvd and cd and radio off/on buttons at the same time but I don't know if that works on earlier years.

This is most interesting. I just replaced a NAV unit to regain HU functionality. But if I understand correctly, I could have just grabbed a TV unit? Obviously no NAV, but it sucks anyway.
