Re: I'll try :-) but the +/- does nothing on mine

I just recently purchased a BMW CD43 radio.The instructions were as follows:
(1)Turn key to "on" position
(2) Turn Radio on then off then on again
(3) Hold "m" down for 10 seconds until "SN#********is displayed
(4)Press the + key 7 times to scroll to tuner area
(5)Area Europe should show in display
(6) press preset key "1" to select USA
(7)Turn radio off
Give it a try ...hopefully this will work for your radio.

Good Luck

I'll try :-) but the +/- does nothing on mine

I need to push 1-2 to go forward and backwords and 3-4 to select or deselect. I just don't see anything remotely looking like a country selection. bunch of other stuff though. Will give it a try or I can just live with it, no big deal, I listen to pre-set channels anyway and never even knew AM was still around. it must have been 10 years when the last time I turned on the AM radio.

Basically same

They all work basically same. Hold down one button to get into service mode. Maybe other than "m".

Then +/- or < > buttons to move/up down menu, number buttons select choice or "1" button is used to toggle on/off binary options.

I think if you play around with your radio using this general info you'll figure out how to configure it.

Thanks but the Business RDS and CD43 are different

but will try and test these. The Business RDS needs the TP button to be held not the M and setup is different a bit.
maybe thats only european setup ?

Re: Business CD setup - need some help

Found this text. Also check the link at the bottom...




To access the service menu in the BMW Business CD:
- turn the radio off, then on again
- press and hold M for 10 seconds
- display will show SN#nnnnnnnn
- press +/- to access settings
- press 1-6 to change settings

Settings I know of are:
SN - serial number
SV - software version
signal strength level
GAL - speed sensitive loudness
DSP - n/a
TP-V - traffic program volume (non-USA feature)
display check
tuner area selection
AF - alternative frequency (non-USA feature)

Cycle power to exit service mode.

Some aren't modifiable - hope that helps.

Business CD setup - need some help

how do we change the country code in the Business CD ?
I bought one from europe and it is in the european mode (shows every number not only odd numbers) and the scan function does not work.

I was able to access the setup menu by pressing and holding the TP button but I can't figure out which setup menu is for the country code.
