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

Either this is the reason for my misfortune or the GarminUpdater 2.8.0 is corrupted, because it doesn't detect anything (sometimes i was holding my finger over the top-left of the screen for 15mins - well, if you're doing something else while you wait you don't get bored... just frustrated lol).
Can anyone give me links for new downloads for the updater and *.gcd that you successfully used for your conversion?

1. Execute updater.exe. Make sure you checked "USB device" on Updater.
2. Turn off Nuvi and disconnect USB cable from PC.
3. Connect Nuvi to PC using USB cable.
4. When Garmin logo appears put finger on the left upper corner on LCD screen and hold it.
5. When Nuvi goes in preboot mode it will be recognized by updater. Press OK on updater.

Hi voyager56!
yes, that's exactly the procedure that I've been following. Maybe this can sound weird for everyone that succeeded by doing this way, but it doesn't crank with my unit. I really am a very methodical guy and take my time to read everyone's experiences before advancing (also like to share my own experiments). That's why I think that perhaps my updater is corrupted, as all steps go ok and only this piece of sw doesn't recognize or "wink" to my 3790 and a few seconds later, though, both windows offers to open mass storage unit and anti-virus to check on it. I have both updater and generated rgn file in the same folder as well. I believe by all the readings that being an LMT edition has nothing to do with the mishap, so I'm losing my hope of making it.
