65-12-6-961-215 RMFD radio.
Doesn't sound nearly as good as original unit.
Just wondering if anyone can answer if the business CD head units are the same for the HK and regular audio systems?
I know HK has different amp, subwoofer, and perhaps speakers but can't tell about head unit itself. Was there perhaps a change of Manufacturer of these head units since early 2002 to now? Or perhaps it just doesn't match up as well with the amp and speakers from MY 2002 as it's a (newer?) head unit?
I have about 2 weeks left on parts warranty for this car....
thanks v. much
I know this reply is about 5 years later. But I found this thread from a basic Google search seeking information on resetting my 65-12-6-961-215 unit for the USA region that I bought on eBay . HOW TO RESET and CALIBRATE YOUR BMW BUSINESS CD53 RADIO: With the engine/car off and key in position 1, turn your Radio on and hold down the M button until some funny numbers show up with - + in the RDS/PTY screen area. Use the buttons you would normally press for RDS and PTY to scroll thru the various settings and information.
Some of the information you will scroll thru are S/N serial number, build date of unit, parts number, SW number and the rest are basically settings that you can change. You will see one for REGION (I think USA or EUROPE come up) and you can properly select your REGION. Also one of the settings seem to be for adjusting your Radio's antenna's AM/FM frequency. I think this was labeled V or something and it allows you to increase or decrease the antenna sensitivity.
They are a bunch more settings that I haven't explored. But setting my REGION correctly and calibrating my Antenna sensitivity made everything better for my 65-12-6-961-215 unit and yes it does play MP3 Data CDs.
Also 65-12-6-961-215 is not a designated Re-manufactured parts. On the dealership computer that number comes up as an original manufacture part.
The way the parts number work is that when a said unit gets re-manufactured or refurbished BMW changed the parts number of the said unit to a new number relevant to the original number so
say if my parts number unit 65-12-6-943-429 got sent back to the dealership and got refurbished. BMW would restock the same said unit after refurbishment with a parts number of 65-12-6-943-430.
The parts number ending three digits increases by 1. So 429 becomes 430.
or a 65. 12-6 941 505 would now become 65. 12-6 941 506 after refurbishment. Which is why when you browse REALOEM you see a lot of strange yet familiar looking parts number.
