Thanks white46. I assume no wiring harness was needed? Pretty much plug and play?

yes. plug and play.
only thing you will need it antenna adapter if you want to listen radio.

if you want to use aux input, you might want to try to make one for yourself.
here is the link to make aux input cable that i did.

Without the antenna adapter or amplifier? If the adapter wasn't installed - you receive any stations.

Great write-up Steve. I just completed this installation and it only took about 15-20 minutes. As you had explained the bottom torx screw is very difficult to get to. My stubby torx screw driver still wasn't able to get to it because of the angle so i thought i would share how i was finally able to get the bottom torx screw out. I took the torx bit off of my screw driver and used it with a socket wrench to get the top screw off. The socket wouldn't work on the bottom screw so I used the torx bit with a wrench as can be seen in the photos below.

Thanks again Steve for the solution to the crappy reception and also for the write-up!

Glad you got it working! Where did you get the antenna amplifier btw? Were you lucky (as I was) to find a used one that had the same frequency?

I had a hard time removing my c-pillar because the damn light won't come off no matter how hard I pry it. Therefore, I was unable to determine the freq. luckily, on the back of my keys, I noticed that the freq was also stamp on there.

any tips on how to remove the light. am I the only one that can;t remove the reading lights on the c-pillar?

I think you just pry it out with a screw driver

Damn, how did I miss this thread? Great job!

I did the radio change but not the antenna amp with the reception loss, but decided it was a fair tradeoff for the added features. Antenna amps are in the $600CDN range up here. Also I found the reception pretty much cuts out completely when the radio is turned on manually (with the car off). I think this is because the amp (in the older cars) is ignition-powered instead of live/remote.

Also the radio I removed (tape) was Alpine built, not Blaupunkt. I think only the CD players were Blaupunkt.

For those with general poor AM reception, it sometimes can be the coax connector at the amp. If you back it off then retighten, it might fix the problem.

Thanks again for posting the DIY.

Mark

I've read that some of them have a screw in the light fixture. You may have to try to remove the lens and remove the screw.

Help! Does anyone know the location of the Antenna Amplifier in an e46 M3 Convertible?

I need to find mine for another project, but of course, I do not have a C-pillar.

I pulled the carpet around the cd changer and removed the back seat, but I cannot find it.

Anyone know?

According to RealOEM, it's in the trunk left side panel:



And just in case you need the audio amp, it is in the interior rear side panel:

Wow, I searched and searched for this information and even misunderstood some of it myself based on what I read in the Bentley manual - great post!

I just ordered the adapter cable for now. I don't listen to AM at all but I still want it to work, but I'll see how I go before spending 150 on a new amplifier!

i realize this is like months later on this thread, but of opposed to replacing the antenna amplifier for $200ish, could you not simple attach the extra wire for the antenna amp to a 12v switched source such as the white wire in the radio harness? I would think that would then turn on the 99-01 antenna adapter. My understanding was that the "extra" wire was to simply send a signal to turn it on when you switched from cd or mode over to the radio function.
