radio disabled after battery disconnect

I have a 2000 528i. Recently replaced the battery, which of course meant disconnecting the battery cables. With new battery in place, the radio and cassette player (plus an aftermarket CD player) have all stopped working entirely. All I can do is set the clock, which still does display. Hitting the power on button for the radio produces no result. Called a local BMW dealer and the service dept. told me there is no code that needs to be entered for this car to enable radio. Owner's manual and BMW radio owner's manual have nothing to say on this. Anyone got an idea for me?

Welcome to Bimmerfest! I've moved your thread over to the E39 5 series forum. Try searching in here for other members that might have had the same issue. I am thinking it is a fuse that is blown, have you checked those?

Thanks, Tim, for locating my query in a better place. I have not checked yet for a blown fuse. My thought is that since the clock is working, the fuses are probably OK, but it's worth a try.

The clock comes from the bus system as you set it from the instrument cluster. If I remember correctly the radio gets power from the amp in the trunk. Fuses are always a good place to start.

D/C the battery ground cable in the trunk for a good 5 minutes.
Then re-connect it.
Make sure during re-connection you don't produce any sparks. Just connect it in one shot.
Don't ask me why but the "BUS" can be frozen under certain conditions, known issues in E39.

The radio has no code.

I doubt the battery replacement had anything to do with the radio problem, but, checking all the fuses seems prudent.

For more information, type /fuse f3 in the VERY best of E39 Links where you'll find these threads which should help:
- One user's attempt at locating and snapping a picture of every single fuse & relay in the BMW E39 (1)

See also this training PDF which covers the radio:

Some say to wait 16 minutes before disconnecting the battery; others say it's nonsense. Take your pick. I always wait, but that's just me.

Is everything aftermarket or do you have original bmw radio unit? If original my 99 528it needed a code to be entered after loss of power so I'm a bit dubious on the dealer response. .not certain how to find the code if dealer is unwilling to help but I'd be willing to bet the coding guys would know how to source that information.

Try this site to verify if dealer is speaking truths: http://www.radio-code.com/BMWPayPageRadioCode.htm

So another thread verified what your dealer said....no codes for E38,E39 and up. I guess it was on my E34, sorry for the bad information, good luck with your dilemma I have nothing of value to add.

This is true.

Since I have the Dice Silverline, I've disconnected my battery so very many umpteen times, that I'd be old and gray if I waited 16 minutes every time I had to reset the MID.

I thought we had a thread on this topic, but the only thing I see in the bestlinks when I type /sleep or /16 minutes is this thread (which is only partially related):
- Shifter light stays on all night because the GM doesn't send the 'go to sleep' signal after 16 minutes (1)

It's probably in the regular battery threads (because I do remember us discussing this).

The entertainment system is proprietary - the components will only work with each other, so the radio, et al, is useless, and worthless, if stolen. I suspect most professional thieves know that.

Not being a thief, I don't really know that.
I guess I should look in the bestlinks for how to steal a radio out of the BMW, but, just out of curiosity ...

What happens if I steal, say, your MID, and put it in my bimmer.

Would it not work?

Yes, it would work...and if you had an e53 X5...it would also work in that model (one of the few exceptions to the rule).

The MID and other audio components don't have an "anti-theft" code in the e38/e39/e46/e53 like the BMW models in the preceding generation.

BMW went away from the anti-theft radios to the multiple component/model specific set-up as found in the models previously mentioned. The exception is the e39 & e53 share the same MID since the X5 was sort of a SUV version of the 5 series.

The one component that does require "coding" is the amp. They all use the same amp (not sure about the e46) but they are "coded" for the "dynamic" dimensions and speaker set-up for each model. If you swap an amp from another model...you will get sound...but it's usually muddled until you get it coded for the model its in and based on the vehicles ZKE coding.

But again, there is no "anti-theft" code required if you swap in a MID from another e39 or e53. The MID from an e38 or e46 won't work because it won't fit into the dash...and neither will the in-dash cassette or CD unit...again, these components are "model specific"...unlike the old anti-theft radios which were used in all BMW models of their day.

The MID performs no calculations of it's own...it's just a simple input DISPLAY device that receives data from the various components: AUDIO/PHONE/OBC/CLOCK/DSP

disconnecting the battery for 20 minutes and then reconnecting had no effect on the lack of radio. Next step is to look into fuses. The chart on the housing above the battery well lists three fuse numbers. I assume this means, "One of the above." No way there can be THREE fuses on the radio circuit, right?

Mmmmmm me thinks there's also a fuse on the back of the HU that isn't listed anywhere on the schematics...

Usually there is a 10A fuse in the back of the unit...

radio fuse update

The fuse chart on the back of the door to tbe battery well in the trunk lists three fuses, 56, 58, and 43 for the radio. The bank of fuse receptacles inside the battery well above the battery runs, from #46 to #66. Place #56 has no fuse. #58 has a 10 amp fuse. #43 is somewhere else in the car. Two photos attached.

Thanks QSilver7, that's a really useful diagram. I'll look into it as soon as I have a chance.
