2007 Business CD Radio

TommyA · 09-09-2015, 12:07 PM

The Car didn't come with any manuals and I am unable to find the correct manual for the CD radio. When the car is started the display shows REG OFF for a few seconds then changes to the station address.
Can anyone tell me what this is?

Found this in an E38 manual:

Quote:

In certain areas no alternative frequencies are found although they can be set with a manual
search.

Cause: In areas that have stations with permanent regionalisation, alternative frequencies cannot be found when regional mode is switched on (REG=ON) if they have another regional identifier.

Radios concerned: All

Note: REG by pressing the RDS button for a longer period (display: REG=OFF) or switch off the REG button.

Not sure if these instructions to toggle the setting apply to the Z4 though.

From what I understand from your post it would seem that it would be best to not worry or change it. What do you suppose they mean by alternative frequencies?

Same station broadcasting on a different frequency? Thanks for the info.
