Hi all, thanks for all the input. It answered most of the open questions, display tool r577 should be able to analyse all the files. Binary is here: https://files.mkgmap.org.uk/detail/543 See also https://www.mkgmap.org.uk/websvn/listing.php?repname=display&rev=576 and https://www.mkgmap.org.uk/websvn/listing.php?repname=display&rev=577 @Nick: the larger MDR seems to cause trouble when section 1 is displayed. Will look into this later. r577 should work with option --print=!1 This option means that all but the 1st section should be printed, will cause huge output for that file, but string decoding seems to work well Gerd ________________________________________ Von: mkgmap-dev <mkgmap-dev-bounces@lists.mkgmap.org.uk> im Auftrag von nick <osm@pinns.co.uk> Gesendet: Mittwoch, 29.

Hi Nick
Thanks.
Interesting, but not maybe not relevant to the Huffman stuff, in mdr16austria.txt the MDR headers go out of sync after MDR30

Hi Gerd
OK thanks will check that tomorrow.
I think it's amazing how far both of you got.

Hi Nick,
yes, and esp. those MDR 16 which do not have a 0x15 at offset 2 like in this example: 000003fa | 000000 | aa 04 15 1b 15 08 cf 00 | record 0 (len: 300, 0x12c)

Hi Gerd
Great but as you confusing, although typically Garmin ;)
I noticed some are called map_mdr.img.
I'll check some other pc s tomorrow; I suppose you are specifically looking for mdr16

Hi Nick,
thanks, the mdr file looks like a very early version with a very different structure. Should help to understand the remaining bits :)

I have done a few for you, including one which causes a java error so added the mdr
