Audi B8 3G high japanese to ECE radio not working
Hi Team,
I have converted an Hnav from japanese to HNav_EU_K0257_6_D1 succsefully. However, that doesn't change the Japanese frequencies, but the radio works fine. We have attempted to do the following Green Menu -> radio change frequencies to European, the MMI reboots and we get the full frequency range, however, there's only a hissing noise and no radio. If we change the frequency back to Japanese, we get our radio back, but with limited frequencies. From what I have been reading, something needs to be changed on the EEPROM through VCDS, but cannot find any info. There's only a VCM script for USA, not Japanese import. Edit: With further testing I have discovered that when changing the region for fm to Europe, the signal strength is between 0-5db, while in Japanese region mode it is around 30db, with the same antena. Anyone have any luck with the above? |

RE: Audi B8 3G high japanese to ECE radio not working
So with lots of gooling I found the following
http://wiki.ross-tech.com/wiki/index.php...(MMI_High) Coding 000000?: Radio Configuration 1 = Europe 2 = North America 3 = Japan 4 = Australia 5 = South America 6 = South Africa 7 = Asia However, when I go to the module I have options to either enter a 5SN or a 7SN code to do coding. I hav ebeen advised that OBD11 could do this anyone have any experience? Also I am getting a VVDI2, does anyone know if that can read the code? |

Try obd11 us to eu...result should be same...byte 00 must be 01 after coding...link you provided should be for mmi 2g i guess, not for 3g etc...
Congo11 may correct me, if im wrong |

Without proper login don't work. Even obd11 don't help.
You don't need special interface, you need knowledge how to do it. |

RE: Audi B8 3G high japanese to ECE radio not working
So my VVDI2 Xhorse tool came.
I can get the follwoing VAG Number: 4G0035083 HW/SW Version: H50 0055 Long Coding: 030005020100000001 Systen description/Type: Radio U JP Based on googling the first byte 03 - Japan (i guess as I can't find info) 02 - USA 01 - EU Got this info from Long coding, 56 radio: 01 = AM/FM EUR (02 USA) 01 = DAB (fixed value) (00 sirius USA) 03 = Operating Mode 01 = External Amp (02 if the amp is inside, e.g.: not B&O) 00 = Sound Profile 00 = No info 00 = No info 00 = No info 01 = Chassis So The issue is when I try to change the first byte to 01, I get coding error. Anyone have any advice how to change the first byte, or do i need to change ECU firmware before this is possible? |

As I wrote before no need special interface.
Without combination of security login, you never change region. Always will be coding error. |
