Can these files be used on a Montana 680t,and is there a thread you can refer me to that lays out, in pretty good detail? With all the files that are available for download, which ones I would need to build an SD card to with my Montana? I would assume a step-by-step thread would be really helpful to rookies like myself.

If you check on what maps you can add, these City Navigator maps are included.
Montana 610/680 | 2299 | 330 | MAP: Yes | GMA: Yes | MSV: Weak | GVS: --- | File: Montana610_680_350.gcd
This MSV Weak means you device does not require patching to use Unlocked maps.
The whole forum is a "How to"
Download the 5 parts of N.America 3.15 GB extract to a new folder on your desk top.
You will end up with gmapprom.img 3.15 GB change its name to gmapsupp.img.
Format your SD card FAT32 and create a folder called Garmin copy gmapsupp.img into there.
File name & location is recorded in your garmindevice.xml

I get that. I just recognize that there is some shorthand in many of threads, and it is a bit much to unravel. Thank you for the concise steps to get it working for me. It does beg the question, what are all the other files about then? If the ROM files are the only group needed, what do the ASR, and SID files help with? When I try to use my Montana to 'Go to' a waypoint in town, it just draws a straight line from where I am. So I assume these files help with the smarts of actually routing streets, highways, etc. From your answer; you are telling me that is not correct.

You've been here a whole day & you haven't read every Garmin post,what have you been doing
Many features are NOT duplicated across all the Garmin device range. Your example ASR is a voice control file,for hands free control of an Auto device,redundant on a Hand held device.
