When you disconnect your battery and then reconnect it again, it disables the radio. This is an anti-theft protection for your car radio.
The enable your radio the activation code is in your vehicle owner's manual. If you do not have this code you need to go to your BMW service centre and get them to enter this code for you.

SOURCE: My Radio and clock screen has went blank volume and controls

it sounds like the Multi information display has failed (MID). It is the long display with all the radio controls on it. If you want to find a known good part they are really easy to swap out. Just remove the radio knob and if you look down in there, there is a place to put a T10 (i think maybe bigger or smaller) torx T10 screwdriver.if you turn it while pulling back slightly on the screwdriver it should come right out. It usually is the component that fails but as always you may want to check your fuses.

try taking the radio out and looking on the top for the parts number. call Honda and tell them what is going on and they will give you a 4 digit code that will reset the radio. i had the same problem with my 05 civic, did that and it worked for me.

SOURCE: I just replaced a battery, and now the radio/cd

The anti theft feature in the radio was probably tripped when you replaced the battery. One solution would be to take the car to a Honda dealership to have the radio anti theft feature reset. A good car stereo shop should be able to reset it as well.

DISCONNECTING YOUR BATTERY without losing the RADIO CODE


I constantly read frequent requests for RADIO CODES referring to the disconnection of battery power ( whether its for changing the battery, etc.) and the radio is now INOP. Here is a simple way to save radio codes, radio stations, clock time and computer settings. Purchase from an auto parts dealer, a 9 volt battery powered lighter socket connector. Plug into lighter, do your battery work, After work is completed, disconnect, and radio will work as before. Unit will cost less than 20.00 and well worth it.

How do I set my clock?


If you have the Owner's Manual there will be specific instructions incorporated in it. Most North American Market vehicles are set in similar manners. Usually the Radio MUST BE TURNED OFF to set the Clock. There are usually two buttons one for the Hour and one for the minutes. With the Radio OFF push the Hour button and hold it until the correct hour is displayed. Then Press and hold the Minute button until the correct minute is displayed. Release the buttons immediately when the correct value is displayed. If this information is not sufficient, please contact you local BMW Dealers service department.

Cd in car stereo won't eject. I have a 2005 Chrysler T&C van and there is a CD in my stero that won't eject. Any suggestions?


Try turning the radio off and disconnecting the battery for 2 min then reconnect the battery and turn on the radio. This may reset the radio to default so you can eject the CD and reset your station preset and clock. make sure the radio is off before disconnecting the battery or your going to be prompt to program a radio code. Good luck and this should work.

My CD is stuck and reading no disc how do I get it out without damanaging my system?


Turn the radio off and then disconnect the battery, wait 2 min then reconnect the battery. Turn on the radio and hit eject, that should reset the radio and you have to set the stations and clock. Note: radio must be off before disconnecting the battery, os your going to have to re-enter the radio code to have the radio active again.
Good luck and keep me posted.

Turn off the radio and disconnect the battery for 30 seconds. Make sure the radio is off before you disconnect the battery. once the battery is reconnected, turn on the radio and eject the CD and reprogram the stations and clock. Good luck and hope this helps.

Unless you Have AoolCodes DEALER IS A GOOD IDEA




Disconnecting/Connecting The Battery

Always stop the engine before disconnecting the battery negative lead and make sure the battery positive lead is isolated i.e. wrapped in a suitable cloth.

WARNING: Radio code saving devices must not be used when conducting work on air bag or fuel systems. It must be noted that, when using these devices, the vehicle electrical system is still live albeit with a reduced current flow.

NOTE: Before disconnecting the battery make sure that the radio receiver/cassette player/mini disc player and compact disc player keycodes are known and, that no data is required from the powertrain control module as battery disconnection will erase any fault codes and idle/drive values held in the Keep Alive Memory (KAM). It is not necessary to disconnect or remove electronic control modules.

Always disconnect the battery before commencing repair operations which require:
  • The vehicle to be jacked up
  • Work on the engine
  • Work underneath the vehicle
  • Arc welding
Alternatively a Radio Code Saver may be used. With the battery disconnected, a Radio Code Saver will allow sufficient current to pass to maintain the radio receiver/cassette player/mini disc player and compact disc player memory, operate the clock and supply the door operated interior lights while isolating the battery in the event of a short circuit.

Reconnecting the Battery

WARNING: If the battery has been on bench charge the cells may be giving off explosive hydrogen gas. Avoid creating sparks, and if in doubt cover the vent plugs or covers with a damp cloth.

Always make sure that all electrical systems are switched OFF before reconnecting the battery to avoid causing sparks or damage to sensitive electrical equipment.

Always reconnect the battery positive lead first and the negative last, ensuring that there is a good electrical contact and the battery terminals are secure.

Restart the clock (where fitted) and set it to the correct time.

Re-enter the radio receiver/cassette player/mini disc player and compact disc player keycodes and preset' frequencies, if known.

Following reconnection of the battery, the engine should be allowed to idle until it has reached normal operating temperature as the stored idle and drive values contained within the powertrain control module have been lost. Allow the vehicle to idle for a further three minutes . Drive the vehicle at constant speeds of approximately 48 km/h (30 mph), 64 km/h (40 mph), 80 km/h (50 mph), 96 km/h (60 mph) and 112 km/h (70 mph) for three minutes each. This may cause a driveability concern if the procedure is not carried out. This will allow the powertrain control module to relearn idle values.

Brake warning light is on for 2002 bmw 745i.


The brake pads have sensors in them, when the pads get worn down to the sensor the light comes on letting you know its time to replace. this happens well before the pads are completely gone to reduce wear on the rotors. You should have the brakes replaced and the sensor also.

89 BMW 735 il wont start


The cause of the display reading E sometimes and S sometimes is a defective transmission module, or getriebesteuerung in German. This module is located in the passenger side kick panel. To replace the module you will have to remove that panel then loosen the 4 10mm bolt which hold the module in place. There is a large set or wires going to this module and it is not simple to remove at first, it takes some twisting and shouting. Make sure your battery is disconnected when you do this and make sure to replace it with a module that has the same part number on it, If you have any more questions I'd be glad to help.
