I re-read countless times and followed all the instructions, but 2 things came up: 1- I don't have a gupdate.gcd file in my Nuvi's system folder (could it be for having the most recent updates on?), so I have nothing to erase; 2- when I try to install the 34xx fw in my GPS, I hold my finger on the upper left side of the screen and see the small "system loading" info above the garmin logo, but garmin updater v2.8.0 doesn't recognize by USB device... i held my finger for several minutes and tryed countless times to repeat the procedure... If I'm not cleared on what's not going right I'll give up.. Thanks for any help!
1. Don't worry if you didn't find a gupdate.gcd file. It's normal.
2. Make sure Garmin Lifetime updater it's not running in background. Check your USB cable. USB drivers must be installed.
