SUBJECT
BM53 Radio: Time Delay When Changing Preset Radio Stations
MODEL
E39 (5 Series)
E46 (3 Series)
E53 (X5)
Production up to June 2005
[NEW] SITUATION
Only with RDS active, there is a time delay when changing radio stations with the preset buttons on the monitor display or with the MFL button.
[NEW] CAUSE
Radio is coded incorrectly, the "AF (Alternative Frequency) function" is activated.
As a result, the BM53 radio checks for AF signals when RDS is active. This may take up to 10 seconds.
[NEW] CORRECTION
Code the BM53 radio via Progman for proper function.
When no control module was replaced, follow "Programming and Coding" outlined in SI B09 05 01 (Coding, Individualization, Programming (CIP), Procedure B).
If a control module was replaced, follow "Programming and Coding" outlined in SI B09 05 01 (Coding, Individualization, Programming (CIP), Procedure A).
1. Start "New session"
2. Select "Series (3, 5, X5)"
3. Select "Model (E46, E39, E53)"

7. Select "Encoding"
8. Select "Start" after "Measures plan is being determined"
