    I would keep it if I could play music from my phone. Would just upgrade the speakers. I could also just source a new harness? Is that also a way?

    You could wire a 3.5mm jack onto the radio pcb so that you could plug your phone in, better still you could hook up a Bluetooth interface. Id need to look at the schematics. Is yours the professional c rds ? Have you got the cd player as well ?

    I'm not sure about the Professional C RDS, but check out this thread regarding installing bluetooth with the CD43: https://www.bimmerforums.com/forum/s...ht=mbarrett635 . I've installed this in my car, and it works great. It adds hands free phone operation, plays music from your phone, plus you can play music from a thumb drive or an SD card. Easy DIY installation, and inexpensive. Since you already have a CD43 radio, this is a win-win.

    But the CD43 works and all except there comes no sound from the speakers. Thats the problem I am dealing with.

    On the bluetooth adapter I recommended? It is surprisingly good. Part of the sound quality is dependent upon the bitrate of the music files being played on your phone. I always choose the maximum size/highest quality setting for whatever music program I am using (i'm partial to Spotify). Of course, as everyone will tell you, the stock speakers in the 8 are most likely the single biggest limiting factor when it comes to sound quality. I haven't changed mine, so it does have its limits. But I'm just happy not to have to listen to crappy radio stations and all their constant commercials.

    When using the stock system, you are absolutely correct.

    Thats what I am talking about. I think the best way would be to change out the harness and put in the CD43 along with some bluetooth adapter and new speakers

    I would change the amp, speakers and wires, and I would go with an aftermarket head unit as well. I know it won't look stock, but if you really want it to sound good, you will have to find a head unit that you like the looks of.

    But I guess the main problem with my car is the harness from the radio to the trunk

    That system uses a separate unit in the back. Other 1-DIN radio’s will not talk to it, hence, no music.

    About 2450/2455 difference, there is another thing (or thé thing): it's the TP function. The 2450 displays T and TP, the 2455 displays the station name. As can be seen in the pictures I posted on previous pages.

    ps. noticed the auto brightness on the 2455 isn't that good, it's often brighter than my obc/climate control. If I put my finger over the sensor, it dimms to a match. Don't feel like taping over the sensor, which on this unit, is behind a nice transparant cover. It seems too sensitive. Never have this problem with my CD43. Also, the CD43 secret menu has a setting for initial display brightness, so you can match it with the obc/mid and climate controls. Unfortunately, the Becker menu lacks this.
    This unit good have been beyond perfect with these little things corrected.
    Hey, I read this topic because i want to find something about becker be2450/be2455 and dension gw lite cd changer emulator. I was testing it with cd43 and it works ok, but when i tried with becker, no effect . I got also multifunction steering wheel and it works fine with becker. Becker also is working fine with factory cd changer but with dension there is no contact (there is no posibillity to change mode to cd changer. Can somebody help mi to connect it ?

    It was my understanding through reading on here that the BE2450/2455 was compatible with the non-ibus CD changers, even though it is a newer-style head unit. The CD43 does use ibus CD changers, which is the protocol used by the Dension. Pin 7 is the "ibus" or multifunction steering wheel link to the head unit, but that is on the main harness, and not on the CD changer connection.

    Here are the pinout details of the cable that runs from the head unit to the RDS tuner.

    What does that give us? Can I modify it somehow for a normal radio to work?

    No this is for anyone wanting to know how to make a cable to connect the professional c head unit to the RDS tuner in the boot. I’ve had quite a few PMs over the years asking for a clear pin out diagram .

    Only just saw your question. The 2450 is Mbus version, 2455 Ibus.

    CD changer, when connected properly, can be chosen by pressing the Mode button 2 times (when in radio mode).
