Language strings are managed through the locale system. The locale string for microphone gain is defined as LOCALE_STRING_MIC_GAIN (29) at locale.h:42.

​
Temperature display

Choose which temperature sensor to display in the OBC (On-Board Computer) view. EEPROM address: 0x20 (lower nibble) (CONFIG_SETTING_BMBT_TEMP_DISPLAY_ADDRESS)
​
Coolant
0x01
Display engine coolant temperatureValue: CONFIG_SETTING_TEMP_COOLANT
​
Ambient
0x02
Display outside ambient temperatureValue: CONFIG_SETTING_TEMP_AMBIENT
​
Oil
0x03
Display engine oil temperatureValue: CONFIG_SETTING_TEMP_OIL
The temperature display setting is stored in the lower nibble (4 bits) of the EEPROM byte: 
// Reading (config.c:456)
uint8_t ConfigGetTempDisplay()
{
    return ConfigGetByteLowerNibble(CONFIG_SETTING_BMBT_TEMP_DISPLAY);
}

// Writing (config.c:884)
void ConfigSetTempDisplay(uint8_t tempDisplay)
{
    ConfigSetByteLowerNibble(CONFIG_SETTING_BMBT_TEMP_DISPLAY, tempDisplay);
}

​
Temperature units

Set the temperature unit for all temperature displays. EEPROM address: 0x20 (upper nibble) (CONFIG_SETTING_BMBT_TEMP_DISPLAY_ADDRESS)
​
Celsius
0x00
Display temperatures in degrees Celsius (°C)Value: CONFIG_SETTING_TEMP_CELSIUS
​
Fahrenheit
0x01
Display temperatures in degrees Fahrenheit (°F)Value: CONFIG_SETTING_TEMP_FAHRENHEIT
The temperature unit setting is stored in the upper nibble (4 bits) of the same byte as temperature display: 
// Reading (config.c:470)
uint8_t ConfigGetTempUnit()
{
    return ConfigGetByteUpperNibble(CONFIG_SETTING_BMBT_TEMP_DISPLAY);
}

// Writing (config.c:898)
void ConfigSetTempUnit(uint8_t tempUnit)
{
    ConfigSetByteUpperNibble(CONFIG_SETTING_BMBT_TEMP_DISPLAY, tempUnit);
}
Temperature conversion is performed automatically when displaying OBC data: 
// From menu_singleline.c:234
if (ConfigGetTempUnit() == CONFIG_SETTING_TEMP_FAHRENHEIT) {
    coolant = (coolant * 9 / 5) + 32;
    if (oil != 0) {
        oil = (oil * 9 / 5) + 32;
    }
}

​
Distance units

Configure the distance unit for speed and distance displays. EEPROM address: 0x23 (upper nibble) (CONFIG_SETTING_BMBT_DIST_UNIT_ADDRESS) This setting is stored in the upper nibble of the byte and controls whether distances are shown in kilometers or miles.

​
Metadata mode

Control how music track information is displayed on the screen. EEPROM address: 0x1D (CONFIG_SETTING_METADATA_MODE_ADDRESS)
​
Off
0x00
No metadata is displayedValue: MENU_SINGLELINE_SETTING_METADATA_MODE_OFF
​
Party
0x01
Display metadata in party mode with continuous scrollingValue: MENU_SINGLELINE_SETTING_METADATA_MODE_PARTY
​
Chunk
0x02
Display metadata in chunks that update periodicallyValue: MENU_SINGLELINE_SETTING_METADATA_MODE_CHUNK
​
Party Single
0x03
Display metadata in party mode for single-line displaysValue: MENU_SINGLELINE_SETTING_METADATA_MODE_PARTY_SINGLE
​
Static
0x04
Display static metadata without scrollingValue: MENU_SINGLELINE_SETTING_METADATA_MODE_STATIC
The metadata mode affects how track titles, artists, and album names are shown during playback.

​
BMBT default menu

Set which menu appears by default when accessing BlueBus on BoardMonitor displays. EEPROM address: 0x1E (CONFIG_SETTING_BMBT_DEFAULT_MENU_ADDRESS) Options may include:
  • Main menu (Dashboard, Devices, Settings)
  • Direct to Dashboard view
  • Direct to Device Selection
  • Direct to Settings

​
BMBT dashboard OBC

Configure what information is shown on the BMBT dashboard view. EEPROM address: 0x1F (CONFIG_SETTING_BMBT_DASHBOARD_OBC_ADDRESS) This setting determines which OBC (On-Board Computer) data is displayed on the BoardMonitor dashboard screen.

​
Monitor off timeout

Set the timeout period before the display turns off when idle. EEPROM address: 0x22 (CONFIG_SETTING_MONITOR_OFF_ADDRESS) Configure how long the display stays on when there is no user interaction.

​
UI mode detection

The UI mode is automatically detected based on which display modules are present on the I-Bus. EEPROM address: 0x0F (CONFIG_UI_MODE_ADDRESS)

​
Available UI modes

​
CD53
1
Radio display with 11-character textValue: CONFIG_UI_CD53
​
BMBT
2
BoardMonitor graphical displayValue: CONFIG_UI_BMBT
​
MID
3
Multi-Information Display with 24-character textValue: CONFIG_UI_MID
​
MID + BMBT
4
Combined MID and BoardMonitor setupValue: CONFIG_UI_MID_BMBT
​
MIR
5
Multi-Information Radio displayValue: CONFIG_UI_MIR
​
IRIS
6
Navigation display interfaceValue: CONFIG_UI_IRIS
The detected UI mode is read with: 
// Reading (config.c:561)
uint8_t ConfigGetUIMode()
{
    return ConfigGetByte(CONFIG_UI_MODE_ADDRESS);
}

// Writing (config.c:1029)
void ConfigSetUIMode(uint8_t uiMode)
{
    ConfigSetByte(CONFIG_UI_MODE_ADDRESS, uiMode);
}
The UI mode affects text length limits, menu layout, and available features. For example, MID displays support 24 characters while CD53 displays only support 11 characters. The menu system automatically adapts to the detected UI mode.
Changing the temperature unit setting affects all temperature displays immediately. The OBC view automatically converts coolant and oil temperatures using the formula (Celsius × 9/5) + 32 for Fahrenheit.
