Thread: Transform a Nuvi 37xx in a Nuvi 34xx for dummies

Same here but it doesn't bother me since it doesn't affect the functionality as 3490.

hello everyone!
Thanks a lot to all of you who used the time to create/feed this thread. I took my time to read attentively to all replies and decided to give my 3790 a shot... Apparently I've been stuck in a "shooting my foot" scenario. 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.

Thank you very much for your help voyager56!
I read about Garmin Lifetime Updater, but chose not to uninstall it and instead stopped its process and put it into Kaspersky's "jail" of untrusted apps. Maybe I should uninstall it, after all its easy to re-install. My USB cable is ok as the pc recognizes the Nuvi and offers to open windows explorer. As for the drivers, if the pc recognizes it, shouldn't it be installed already? I'll give your advice a try and uninstall GLU and check if I need to install any drivers for the GPS. I'll post my results...
Best regards!
