Thanks too shahost for that interesting little tool, nice work.

Also these's another way to avoid using a hex editor to trim the unwanted first bytes. An img file can be extracted from any such rgn file by opening it in [Only registered and activated users can see links. ], pressing 'Save' button on first section [unknown.bin] and then changing the name as appropriate when saving, in this case to gmaptz.img.

RGN Tool TZ1602

That trick will work using RGN_Tool for any other similar support file from Garmin such as a Voice presented as an rgn file to convert to a vpm etc.

I'm reasonably happy to work with a hex editor now, but having no prior experience early on looked for and found all sorts of ways to avoid doing anything in hex in my very noobish days playing with garmin devices. Now graduated from 'very noobish' to 'noob'
