Hi I have BMW 750 Li (2006) before a week ago I was in my car,badly some water fall on the machine (i dont know what it the name of it) which control the menu and the screen now I cant use the navigation system and Entertainment and everything on the screen menu,I dont know what to do now

In some cases the player communicates via the radio by which all activity generally is computer controlled. The BMW computer brain may need a reset or adjustment. This generally requires a technical tracing by computer at the BMW shop. They have equipment to make adjustment. Sounds easy, but today the manufactures make it hard fro the average individual to make adjustment these days.

The Navigation unit needs to be recoded. Did you replace the unit recently?

If it is like earlier models, open trunk, move rug away from back edge, turn socket to unplug and access bulb.

Hi Anon

please see link below it gives you instructions and also shows you photos on where and how to replace it, hope that helps

autozone and others will check and report for free. they wont clear but you should know the code anyway. you can get your own OBD2 reader on Ebay for about $20

Radio failures occur regularly after all they are prone to shorts , over voltage, surges, incorrect polarity hook up etc. The problem I think is that the radio installer hesitates to work on your unit because he may want approval from bmw to work on it possibly under warranty. Some vehicles state that any unauthorised work voids warranty. Clear the air with the radio teck and find out his problem exactly and if still in doubt take it somewhere else.

You should have the control module checked by a tech as either their is too much slippage or it is interfering with the anti-lock system.

hi well no not really the transmission and the brakes have absolutely nothing in common. brake booster? ummm..dont think so, master cylinder is a good possibility 2 ways to find that out, check inside under dash where brake pedal is, if its damp there is a good chance its the master cylinder, if not, where the you put the brake fluid, check the under it see if its wet, see if the brake servo has fluid around it as well the other thing it could be is air i the brake line and that could mean something is letting in air the way to check this is, run motor, press brake semi hard, then without taking foot off brake pedal slightly raise your foot ( but keeping pedal down ) then do it again if it starts to "sink" this means there is air in the system hope i have understood your question...

you will require to take the car to a dealer to resett this

press the satrt button with foor off the brake until lights turn on,close the doors and press and hold the trip button on the inst cluster,abs will come up and then go,than you will see all the diff cbs requirements on left side press button until the brakes come up and press and hold again, it should reset to ???tkm
