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

Even if it shows 37xx it acts like a 34xx.
Clear non vol as explained, it's important and look better for MTP : read

Then run Webupdater

First you enable "new" features (mp3, video, etc) with the xml files (copy all of them together) and then you will use webupdater to update the firmware and all the additional features, downloading the proper files for 34xx (like keyboards etc.).
Webupdater recognizes your device as 34xx now, and all the files you can see in the additional updates section of webupdater are for a 34xx device.

With recent firmwares copying .xml files wont enable features, to do it must use sd files or use enable features application.

It wont work with sw 7.60 :read my previous post n 741. Use sd to enable features and logo.

Also, you said that next I should run webupdater ...... was an update to continue, which was v7.60= 34xx firmware

Yes, if you followed my starting post ,you renamed some folders before converting(Text, keyboards etc,) , well you can delete them and run Webupdater to get 34xx ones. Some other needed files Webupdater doesnt download are posted in this thread.

I already told you, it shows 37xx, but it acts as a 34xx. Because Webupdater reads GarminDevice.xml and it's a 34xx GarminDevice.xml
Your 37xx doesnt exist anymore, it's a 34xx now. Forget 37xx!.
Read threads posts, you'd save your time .

1) Webupdater is needed to download files for 34xx, some are different from 37xx ones.
2) files for sd are the easiest way
Read post n1 if you prefer an alternative method with updater.exe in preboot mode to flash logo, but with sd files you'll abilitate 34xx features too like mp3 and video player etc.
Read posts all is explained properly, no need to repeat

Yes Caty, you're right.
That's why, when I manually transform a 37xx->34xx I use the old 3.60 firmware for 34xx.

@SAVVAS
GarminDevice.xml recreates itself everytime you restart nuvi, you can edit it ,but it will return to its original version when you restart. You can even delete it and nuvi will rebuild it like it was.

Converted 37xx to 34xx shows 37xx in Settings/about and in starting screen. There is a quite complicated way to make it show 34xx, but it's completely useless.

GarminDevice.xml is not to share on public forums because it contains personal maps codes and Nuvi ID. If published someone could clone your nuvi.
