Far from all of the signs (crossroads) are present now! Probably Garmin buy this info and provider of the info have limited quantitiy of ready for use picture today.

Anyway you may split JCV files into a big quantity of picture by digital signature of usual picture like JPEG and PNG in text or HEX editor easily. But you recieve a lot of separated images - crossboard photos separately, sign images separately and rose direction arrows separately. Other solution did not find?!

tom1807, I can't find the.asr folder on my 3790 and even by ticking the show hidden files as well as the webupdater. I need english_american.srd file for my voice command

Garmin will automatically determine your current time zone. From your location, it will calculate which time zone you are in, thanks to a small map file in the unit's memory. This is a nice feature if you frequently change time zones, because your GPS's time will update automatically.

Is there a list of units which support this feature? My 855 doesn't seem to....

TIA,

Ah bummer - I tried adding the map to the 855 but nothing changed. I assumed its firmware simply didn't support this, but hoped there might be some trick I'd missed or overlooked

Oh well, it's a pain, but I can live with changing timezones manually (still).

Thanks!

Excellent! Thanks for sharing!

Catymag,

Can you please upload all the ASR files.

ASR files, if they exist are normally posted with the maps. Which ASR files do you need? And do you have a device which can use them?

Untick the "Hide protected operating system files" in the folder options. Then you will see the .system folder. Please note the dot in front of system folder.
You haven't told us, which map u are referring too, but the SRD files haven't been updated for example in the latest European map
