Unhooking your battery is not good on your computer mostly bmw because of all the components in your system are computer control so unhooking your battery is not a good idea..anyways you might check your owners manual it should have code..

I put in the rwong code now my radio will not let me put in the correct one. What can I do


You must have entered in the code wrong 3 times. when you do this it will chnage form code on the radio to code lock. you have to let the car sit for a hour with the key on and it will reset the radio and let you enter the code. unfortanitly this is the only way to get the radio back to say code. make sure you hook up a charger to the car so your battery doesn't die also make sure your key is in the second position the one right before starting the car.

I just had a new battery put in my Bmw 2003 325Ci. How do I reset the radio? I have the original radiopass serial number card.


I am puzzled. I would have thought that your car is too new to have a radio theft protection code, and too old to have a bluetooth code.
Assuming I am wrong and you do need a theft code, you turn on the radio and the display says "CODE". You punch in the numeric code using the numbered buttons on the radio.
If you try three times and don't get the code right, you have to leave the radio turned on for an hour while the car is running before it will give you another chance.

My radio in my 1994 540i bmw is off beacuse i didn't put the code in soon enough, what do i do?


Is the problem that you did not put in the code soon enough, or that you tried three wrong codes and locked it out? I don't think there is a time limit, but all of us have punched in wrong codes and locked out our radios before. If the display says WAIT, you tried three wrong codes.
If it is locked out, you have to drive for an hour with the radio turned on before it will let you try again. If you disconnect the battery during that hour, you just reset the 1-hour timer back to zero so you have to wait longer.

Resetting computer


There is a long drawn out procedure to do this, however, the simplest solution would be to unhook your Negative Battery cable, and if you like, the Positive one as well...Over-night (or for at least two hours). When you reconnect them, then the code should be erased from your "Trip Computer" and your car should start fine. I take it you're not speaking of the "radio code." Should this not work completely, remove the glove box door, while the battery's un-hooked and unplug the connection to your Motronics, or "computer" for ten seconds and that should erase any previously set codes you've entered.

Hope this Helps,

Radio won't reset. i have the code but nothing ha...


If the wrong code is entered a few times it won't take one at all. Unhook your battery for about an hour and try again.

Radio code


If you have tried a few times before NOT entering the right code or making error when entering code. This radio will lock you out, here is what you do disconnect battery cable for 60 seconds (positive cable) or disconnect radio fuse. Then re-enter code make sure that you are pressing firmly on number and make sure that you enter correctly.(POWER ON RADIO SHOULD BE IN ON POSITION WHEN DOING THIS) If this doesn't work then you will need to go to HOnda and fora fee they will be able to get code. Good Luck and thanks for using FIX YA.
