[mkgmap-dev] Trouble with merging IMG files (for Garmin)

Thu Jul 13 18:51:48 BST 2023

Hello,

should work as Ticker says:  --input-file=./otm-hungary.img

 > ...but I thought I can merge multiple IMG files into a single one 
with Mkgmap.

AFAIK you can. Just keep an eye on the typ-files, that is: use identical 
ones.
See: https://www.mkgmap.org.uk/pipermail/mkgmap-dev/2022q4/033990.html
