Mein Auto: 2006 BMW 325i
Radio

Hello guys/gals. I am new to this site and thought I would ask a question here to see if anyone had any ideas. I have a 2006 BMW 325i and the radio was working one day and the next day I went to start my car and the radio would not turn on. No time, no radio, no nothing. The air still works, the CD still kicks out, and the lights around the radio still light up. I have no clue what is wrong. Here is what I have done so far:

1. I had a new battery put in less than a year ago, so not the battery.
2. Replaced fuses 2, 23, and 31. Still nothing.
3. Held the button in for a while, not on mute.

I cannot believe it worked one day and the next nothing.

I never had a radio just die like that before. Any ideas would be greatly appreciated. Hate to take it in to BMW for something I can do myself. Thanks

Welcome to Bimmerfest! I've moved your thread over to the E90 3 series forum. You'll get more help from other E90 owners who might have had the same problem.

Good luck,
Tim

Did you register the battery and what are your driving habits

Did you register the battery and what are your driving habits?
You should still check the battery first . Measure your battery voltage
and the running voltage of the car.
BMW has this thing called the IBS system that has the ability to shut
unnecessary loads off if it detects low battery voltage.
Also was the replacement battery sized right with respect to amp/hours

Read about it here

http://www.bawarec.ru/manuals/3er/e9...3er-e90-12.pdf
Could be something is wrong with the IBS but most likely is battery or alternator.

The resting voltage of the battery should be 12.5 or higher with the motor running a
around 14 to 14.5 volts is what I read on my car or cars.

These cars are noted battery hogs. If you do not do regular highway driving or if the car
sits for weeks it will deplete the battery . Also working on the car depletes the battery
because the car stays awake. Locking the car will cause it to go to sleep faster this has
been recommended for people with battery problems if you fall into the low use category.

Another way to check your battery voltage if you don't have a meter is using item 9
in the hidden menu list.
http://e90.wetpaint.com/page/BC+hidden+menus

If the the battery proves to be low charge it and see if the problem goes away.
If you are loosing the time setting on your dash that is a pretty good indication of low
battery voltage. It could be there is a parasitic draw on the electrical system to.
Not many report the radio actually going bad here . Most of the audio problems come
from the amp in the trunk , usually because it gets wet.

Okay, just went to Auto Zone and they checked the battery - checked good. Um, battery was purchased from BMW and they put it in, so I'm assuming the battery was checked for everything. I am really getting annoyed at how many problems BMW has. Previous problems were passenger air bag lights, water pump, Cylinder replacements. After about 6 years they just fall apart. Wanted to get another one, but considering all the after warranty problems, it is not looking too good for that happening.

Thanks for your post, I will just have to bite the bullet and take it to BMW to have it checked out. It's really a love hate relationship with this car.

What radio do you have? Nav, no nav? CCC (2 CD/DVD drives) or CIC (one CD/DVD drive)?

If it's the pro nav HU coded for L7, there could be a break in the MOST loop or a faulty/hanging module on the loop. Any break in the loop or any module that is malfunctioning will cause all modules on the loop to hang. TCU is a common failure.

If you have heated seats, turn them on. It's one of the first convenience features that are disabled when the IBS senses the battery is not in a good condition. If they turn on, you can most likely rule out a faulty battery.

OMG, you guys have some niiiiiice BMW's. Okay, here is the scoop on mine. It is old, 2006, no fancy smancy anything. It says bmw professional on my radio, one cd holder. Just a basic radio. No heated seats, no navi. I guess it just died. Ima go to the dealer and see how much it will cost to replace. If it's gonna be too much, which I'm sure it will be, I'll just go to a stereo place and get a good one. What do you think?? Or should I continue to take to BMW?? Warranty is out so....

I would suggest aftermarket. Dealership will charge you $150 just to look at it and least $800+ for a replacement plus labor. You can get a nice Pioneer double din Navi unit installed for about $500

If you are looking for stereo info look here.

If you want to modify you stereo
http://www.e90post.com/forums/showthread.php?t=641323

You might get quite frustrated trying to put and aftermarket stereo that involves
a aftermarket head unit in your car . There are side effects to changing out the stereo and you really don't know what the cause of the problem is yet it still may not be the Head Unit.
Also you will find that most car stereo shops have no idea of how to do a BMW right
and may mess it up .

here is some info on the BMW systems.

I would suggest you get a code reader and read for error codes as a first step to finding the true
source of your problem.(or take it to someone that has one) If you run into the first car stereo shop
you see or even an average one you are really rolling the dice with your car. The way the radio is integrated with the rest of the car makes it difficult to do anything to it without major side effects.
There are several communication and control buses attached to the radio.
If you have repairs done to the car that require programming or writing new software values
to the car the BMW diagnostic computer at the dealership requires that the BMW radio be attached and powered up. There are ways around this with a coding setup.

I'm on my third or fourth radio and third or fourth software update. I have the "Platinum" extended warranty, that covers the radio. (The consensus on the interweb is that the "Platinum" isn't worth it on a car with no Navi, like mine.) The car started having problems with the radio early in life during the original warranty period.

My best failure yet was driving back from Thanksgiving dinner and I was telling my daughter -- who drives a Honda Accord -- that BMWs are a lot of fun to drive and "really not all that unreliable" (she was having trouble stopping herself from laughing!) when deus ex machina, the BMW poltergeists intervened, the radio quit, half the radio display went blank, and the other half showed machine gibberish.

TODAY, after I read your post, I was out driving the car and the radio quit, again. I have the display, just no sound/popping from the speakers. I scheduled a service appointment for next week.

Many, many years ago, I drove a car that didn't have a radio. I kept a small transistor radio on the dashboard. I might need to start doing that again. The automobile radio was introduced in 1930. One would think all the smart engineers who work for BMW would have this figured out by now.

Well, good luck!

Hahalol. That was a great post. I apologize for laughing, but you really made my day. I have a 2006 Toyota Corolla and she is getting more brownie points than my BMW, that's for sure. Toyota was right, BMW's may look pretty, but if you want a trustworthy vehicle, Toyota beats it by a long shot.
