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

**Neil** · 2nd October 2012, 01:12 AM

Caty, this is almost OT, sorry, but i think important. NV backup is such an vital recovery tool and unfortunately is still not widely known of, used and even less properly understood (and potentially misused although with good intention, as in the case earlier on this page but dangerously misused nonetheless though lack of understanding). Good you've added extra info to post #337 to help stop that and i know it's listed in the Tutorials Index but it's a bit hidden away under 'Modding' near the bottom. Do you think it's important enough to have it's own sticky, or maybe be a bit more prominent in the Tuts, perhaps even both?

PS: It's showing as 'Post #338' in the Tut index too, moved back coz of a deleted earlier post here maybe.

Yes probably you're right.
I can copy it in a new thread and naturally correct the link in index-
I think it can be misused if users share it, and for this it's important to make users understand what it's inside region 41, I agree

But first of all we must make users understand to do it before flashing anything different from the official Nuvi model dedicated software update file ...... may be the official one too sometimes

done, new link

When i dwnld new maps for my modded nüvi, the 34xx uses the SID-Folder and the original 37xx uses the G2S+DB? Am i right?

Generally speaking Yes.
But in my 34xx SQLITE (so .db) is still in use.
String from my GarminDevice.xml:
<Path>.System/SQLite</Path><FileName>D3413030A.DB</FileName>

Thank you,
yes i have a .db file provided by the new maps too, but that one is much smaller than the one that probably goes with the g2s file on the 37xx.

g2s is GarminAdjacencytoSSID in 37xx
Separate *.SID files do this work in 34xx

Rename folders and run webupdater ,it should download all the files for 34xx

Edit:Keyboards are also posted by paramas in this thread and linked in post n1 if webupdater wont download them.
