I am wondering (out of curiosity) is that possible to make backup of Satnav DVD?
I've been playing with it and here's what I've found so far:
1. The DVD is made by Aisin and has maps in KIWI format.
2. The disc is DL but and has three types of FS (ISO, UDF, Juliet). Which still refers to one track (you can access it in different ways).
3. The file structure is as follows (for UK DVD):
<206> - Bootloader v2.06
<214> - Bootloader v2.14 Don't ask me why there are two BLs.
<BMP> - Pictures in BMP format. These show maps coverage.
<IDX> - Index files for KIWI database. Consists of numerous files divided by the following categories: ARCSR (?), FMCD (?), FWYD/SR (Freeways?), ITSSD/SR (?), POIDT/SR (Place of Interest), SADSR (Address?), TELSR (Telephones?).
In the root directory there are the following files:
[ALLDATA.KWI] - Map data in Kiwi format
[DICVCE56.KWI], [DUMY0E.KWI], [DUMY1E.KWI], [DUMY1S.KWI] - Got not a single clue about these.
[INDEXDAT.KWI] - DB index
[LOADING.KWI] - BL or OS?
[VOICEDAT.KWI] - Voicedata
[COVERAGE.TXT] - List of BMP maps
[VERSION.TXT] - Version which you could see when you press Map Info button.
I tried to create DVD with only essential files on it (without POI indexes, etc). The disc size was 4.5Gb, which is OK to fit on a single disc. The result, however was far from satisfactory - this disc was rejected. I am not sure why: it could be because the original was created in ISO 9660 mode, where I couldn't recreate this due to ALLDATA.KWI being almost 3.5Gb. As you know, the ISO 9660 doesn't allow files more than 2Gb, so I decided to use UDF 1.02 (I know, it is bad, etc, but...) So, disc wasn't recognized.
It could be because of UDF or +RW or just a DVD brand... who knows.
Anyway, I am going to try couple more times with different settings.
BTW, if you want to know more about KWI (or Kiwi, that's it), here is
the latest spec of data format:
http://kiwi-w.mapmaster.co.jp/documents_eng.html
This is KIWI consortium headed by Toyota Mapmaster (note the URL),
while Denso and Aisin are both members of it.
Do anyone of you have more information about these kind of DVDs copying? I'll try to copy it once again by using ISOBuster and DL DVD burner over the weekend.
