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

You can't change this number in easy way if this be so easy than all who convert from 37xx to 34xx will change this number.
Garmindevice.xml is created automaticly on boot so if you change anything inside xml after new boot will be overwriten.

PLEASE read first post and tutorial Index and you learn a lot of thing and you will also figure out that you can't change number on first screen if you change something in xml.

Only way to change this number is in reg 41 but you can brick your device and this is reason why nobody change this number and you also must know how to convert reg41 that you can then see what is inside this region.

Quite the same words and in the same time

Ok guyz , after reading your almost identical responses now I can rest in peace, everything is working as it should be according to what has been said! I made a mistake and move on straight with this tutorial without reading the other corresponding tutorials , hopefully evererything went well in the expense of time and the help from you guyz!!! Carry on your excellent work-contribution.

hello cat,
successfully transformed my 3790T to 34xx thru your post but is there any way to get the keyboard changed to "qwerty" type? i am not used to "abc" kind of thing. thanks

keyboard is set to qwerty now. thnks once more. another thing i need to rectify is the sound. i can't get the sound on no matter how i adjust the volume mixer. i even have updated the firmware already thru the web updater. i even downloaded the 3 rar files of voice in page 1 and have it placed on the nuvi directory but still i can't here sound on the media player and on the traffic simulation. am i missing something? i like this fw if only i can get the sound working on this one.

And now you create another mistake

This must be my biggest mistake after trying this procedure however I am positively-strongly surprised finding out my mistake, so let me FIX - rephrase of what I should have said from the beginning : Thanks again guyz, girlz and Caty (you see I am giving her special-individual thanks to compensate for it )
