I think when you update via "myGarmin", it will update the voices on you device. If you look under the voice folder, you will see some of your voice files will have same timestamp as when you did upgrade via myGarmin.
I am hoping someone will share their *.update file under Garmin/Update directory for 4.80 to see what is the different from 4.70.

There are two files that were dated when I did the update. Both files were pretty small. The supposed update took over a half hour. I was going to cancel it, but got the warning that my device may become inoperable.

maybe something else changed in one of the other folders, the modified time would be only way to know. This is one of the reasons I hate doing updates via myGarmin.

I have updated my Two Garmin Nuvi 855 thru Garmin's WebUpdater, and got updated from Software Version 4.60 to Version 4.70. My unit numbers are 36XXXXXXX, which may explain why I do not get Software Version 4.80 as per above unit with unit number 35XXXXXXX. But I still get the FREEZING problem almost every time I start my trip for the first 3-5 minutes after which I had to pull out the battery to reset, very inconvenient while driving!. If Software Version 4.8 will get rid of this freezing problem I would like to get it too. But how can I?
