BM53 is for us/asia market only it can be set to eu mode
I am not shure that tmc will work, but all the radiostations will


Turn on the radio. -Within 8 seconds, press the "INFO" button. -From the info screen select RDS -Press and hold the BM control knob for at least 8 seconds. -Scroll through functions using the station < > search buttons. -Turn off the radio to end the service mode

If that does not work try this
1. Turn the radio on.
2. Immediately press and hold the 'Select' button for at least 8 seconds. The screen will switch to Service Mode.
3. The screen will now show the serial number of the radio.
4. Use the "< >" buttons to select the desired service function.
5. Selections for the desired service function can be made by using the radio station preset buttons #1-6.
6. Turn the radio off to leave the service mode.

Service Mode Functions
1.Serial Number: Display of the radio serial number.
2.Software version: Display of the radio software version. Displayed as (calender week, year, version)
3.GAL: Speed-sensitive volume control. Can be adjusted from level 1-6 using the 6 pre-set audio buttons. Vehicles equipped with DSP do not use this feature.
4.Field strength and Quality (F/Q): The station currently displayed can be assessed for field strength and quality. An "F" (i.e. F15) number is used to indicate the strength of the signal being received by the radio. This is a good test of the antenna system, station signal, and the radio itself. A "Q" (i.e. Q-00)number is used to determine the quality of the radio station including both the audio and RDS signal if applicable.
5.DSP: This function provides information about whether the vehicle is fitted with DSP. The value is displayed as a one (fitted)or zero (not fitted) and is communicated by the DSP amplifier via the I/K bus.
6.TP Volume: Provides adjustment for traffic report minimum volume. Not used in the US.
7.AF: Alternative Frequency tracking setting. Not used in the US.
8.Area: Used to select the appropriate market setting (USA, Canada, Europe, Japan and Oceania). Adjust using the pre-set buttons.
9.Index: Display of the revision index.

Try setting it to Europe (8) and se if that will do you any good.
