sorry if this has been asked before... my Nuvi 710 has just had latest software update and now when i start it and go to 'address' it shuts down completely... also found that if you select 'intersections' the same thing happens... any clues folks??...many thanks in advance
You could certainly try rolling back the firmware. If you didn't keep a copy of the gupdate.gcd file previous versions are available here http://gawisp.com/perry/nuvi/
Yours is a 700 series model so the 7xx software should work on your 710, it's available on that site for 4.90 and 5.40 software versions.
Download the gcd file, rename it gupdate.gcd and pop it into the Garmin folder on your nuvi, reboot and it should reload the software. You may get a message telling you that's it's an older version but then you know that already :)
I don't have your model and am assuming it doesn't have a .system folder like the current nuvis. If by chance it does the file needs to be put in the .system folder
