    The first thing I would do is to try and perform a map update on the system to see if it resolves the invalid data issue.

    You can get the latest map updates for the Discovery Pro from the following link (you will need to download 7zip to uncompress the downloaded files)...



    Instructions for how to perform the map updates can be found here...



    The information on the boot-up splash screen usually comes from the firmware so it might need a firmware update to get the correct model logo (GTI) on there if it's something that bothers you. I would have thought that this is something the place that sorted out your Component Protection and seatbelt faults should be able to do for you.

    Right guys, bit of an update !!
    I coded my new unit with the coding from my original japanese unit...and guess what....i lost all my UK FM channel frequency again !
    so went through the bytes 1 by 1 changing them until it changed back and found out that byte 9 on the jap unit was 21, byte 9 on the uk unit was 11, changed it back and hey presto, FM channels are back !! so it looks like it was just a coding change for the frequencys !!
    i still have no nav working though now ! or no compass in my clocks, just says no nav data

    so im thinking, what will happen if i put my old unit back in and change byte 9 to 11 ? i should be able to get FM channels but doubt the nav will work !!

    i have got the coding numbers for both units so will put them up to see the differences and if anyone can give any advise

    0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 bytes
    02 73 00 06 FF 00 00 00 21 33 00 01 00 10 00 00 1F 02 03 26 01 00 01 00 76 japanese infot unit
    02 73 00 01 FF 00 00 00 11 11 12 01 00 08 00 00 1F 02 02 C6 01 00 01 00 57 European info unit

    Did you try downloading and installing map updates from the links in my previous post? If so, what happened?

    No not yet mate, just wanted to check to make sure it wasnt a coding issue first !
    going to get a SD card today and give it a go tonight...fingers crossed

    thanks again

    Glen: Great to hear that your quest to "anglicise" your Japanese car is progressing well. Your discovery regarding the role of Bits 4 & 5 of Byte 9 in address 5F certainly is interesting. But, I'm not sure about your hypothesis that setting these Bits somehow determines the frequency range of the FM radio.

    In Australia, we also adopted the CCIR Band-plan (as did the UK) and our frequency spectrum for FM radio is 87.5 Mhz - 108 Mhz. This spectrum is the same as that used in the UK . On my 103TSI Golf, the setting for Byte 9 is 11, the same as the setting that worked on your car for the UK. This adds to the veracity of your hypothesis!

    However, there's a problem (I think) on the other side of the world!

    Japan's FM radio spectrum appears to be unique because its it's squeezed-out at the top-end by their analogue TV channels which occupy the band 90Mhz-108Mhz. This means that the entire FM radio spectrum in Japan is only 14Mhz wide and it's range is only 76Mhz-90Mhz. Contrast this to how FERC has determined the FM spectrum in the US where the range is 87.8Mhz - 107.9MHz (i.e. more like the spectrum width in Europe, or Australia).

    Why am I telling you this - I can hear you asking? Well, I have in my database the coding values for address 5F for a 2015 Golf S 18TSI /5MT and a Autobahn DSG both of which are NAR models. Byte 09 in both these vehicles has a setting of 21, the same as for your original Japanese Golf. So I suspect there are other factors at play here - alas!

    My suspicion (it's just a guess really) is that the settings for Bits 4 & 5 might be some type of "region-code" which needs to be compatible with the radio frequencies for that region (rather than a software command which determines the frequency spectrum of the radio). But I agree that more data is needed. Perhaps others in different countries could fill-in the gaps?

    I'm also not sure what happens if you try to put-back the Japanese radio into the car. How does Component Protection deal with reverting back to original equipment once it's modified to accept new gear?

    think i have give you the wrong byte numbers don ?? i wasn't allowing for 0 so byte 9 is 33 on jap unit and 11 on UK unit !!
    see pic below, wont let me space the numbers out on here for some reason so made a drawing !

    Glen - I reworked my data with the correct info. Still think that we need to include more countries before we put a tick next to your hypothesis! Anyone out there willing to share their Byte 9 setting?

    Just continued scrolling through your photobucket account...
    ...erm, a bit of a Ford obsession going on there mind.

    Mind you, I did spot some Quantum paper doing a bit masking.

    I checked about 180 [5F] ECU's from VW, Audi, Seat, Skoda (most European) all:
    0x11 Europe
    0x22 USA (Panama and Costa Rica)
    0x51 Australia (2 autoscan)
    0x33 Japan (The one from TD&MCK Car Sales)
