If you use gmaptool, and click on details, then you would see it... e.g. a sample output (makes me remember to change the sourcecode attribution from ccbysa to odbl..., something that should be done in trunk too...): File: D:/Garmin/openmtbmap/us-northeast/65310014.img, length 3437056 Header: 06.11.2012 17:44:37, DSKIMG, XOR 00, V 0.00, Ms 0 Mapset: US-Troy fat: 400h - 600h - 4600h, block 512 maps: 1, sub-files 5 Sub-file fat length 65310014 RGN 600h 1692620 65310014 TRE 2200h 7820 map 3e48d3e (65310014) date 06.11.2012 17:44:39 priority 31, parameters 1 4 23 0 levels [13,14,16,18,19,20,21,22,24], zoom [88,7,6,5,4,3,2,1,0] N: 43.593750, S: 42.714844, W: -73.696289, E: -72.817383 OpenStreetMap and contributors www.openstreetmap.org Map data licenced under odbl http://creativecommons.org/licenses/by-sa/2.0/ Map created with mkgmap-runknown Program released under the GPL 65310014 LBL 2400h 210838 CP 1252, Western European Sort 65310014 NET 2800h 389486 65310014 NOD 3000h 1117500 Map length s-f CP prio PID FID name 65310014 MPC 3418264 5 1252 31 End.

I think that happened when building from source on a windows machine, don't know it that is fixed now.

n Willink wrote Thanks for your advise.
I'm looking at the raw data using my own software to parse the TRE ,RGN,LBL NOD MDR etc of an img
As far as I can tell there is no reference to mkgmaps's version number , ie 2179,2370 in the img file itself.
By difference I meant looking at the contents/order of maplevels & subfiles in TRE or the POIS found in MDR4 using the same osm but different versions of mkgmap
Currently, I'm encountering some very strange & alarming behaviour when the gpx of a route disappears when zooming in .This only happens when I don't need splitter. I've never encounted the priority of an img override that of an IMG

Hmm, you should find the string Map created with mkgmap-rxxxx in the *.img file. Don't you?

What tool do you use to compare two img files? If you just compare the files, you will see a lot of differences even if you use the same mkgmap and the same input. My identical_output_v2.patch might help, but one has to adapt it to current mkgmap releases. See also http://gis.19327.n5.nabble.com/Small-holes-in-boundary-coverage-tp5569161p56...
Ciao, Gerd
